    2016-01-01

    Full Text Available Cataract remains the leading cause of blindness in Africa. We performed a systematic literature search of articles reporting barriers to cataract surgery in Africa. PubMed and Google Scholar databases were searched with the terms "barriers, cataract, Africa, cataract surgery, cataract surgical coverage (CSC, and rapid assessment of avoidable blindness (RAAB." The review covered from 1999 to 2014. In RAAB studies, barriers related to awareness and access were more commonly reported than acceptance. Other type of studies reported cost as the most common barrier. Some qualitative studies tended to report community and family dynamics as barriers to cataract surgery. CSC was lower in females in 88.2% of the studies. The variability in outcomes of studies of barriers to cataract surgery could be due to context and the type of data collection. It is likely that qualitative data will provide a deeper understanding of the complex social, family, community, financial and gender issues relating to barriers to uptake of cataract surgery in Africa.

  2. Small incision cataract surgery: Complications and mini-review

    Full Text Available This article reviews the literature on manual small incision cataract surgery (MSICS and its complications. Various articles on MSICS published in indexed journals were reviewed, as well as the sections on complications of MSICS. The Pubmed search engine on the Internet was used to find out articles published since 1985 on MSICS in any language in indexed journals. Books published by Indian authors and the website of Indian Journal of Ophthalmology were also referred to. MSICS has become very popular technique of cataract surgery in India, and it is often used as an alternative to phacoemulsification. Studies on its efficacy and safety for cataract surgery show that, being a variant of extracapsular cataract surgery, MSICS also has similar intraoperative and postoperative complications. The considerable handling inside the anterior chamber during nucleus delivery increase the chances of iris injury, striate keratitis, and posterior capsular rupture. The surgeon has to be extra careful in the construction of the scleral tunnel and to achieve a good capsulorrhexis. Postoperative inflammation and corneal edema are rare if surgeons have the expertise and patience. The final astigmatism is less than that in the extracapsular cataract surgery and almost comparable to that in phacoemulsification. There is, however, a concern of posterior capsular opacification in the long term, which needs to be addressed. Although MSICS demands skill and patience from the cataract surgeon, it is a safe, effective, and economical alternative to competing techniques and can be the answer to tackle the large backlog of blindness due to cataract.

  3. Femtosecond laser-assisted cataract surgery: A current review

    Majid Moshirfar

    2011-01-01

    Full Text Available To evaluate the safety, efficacy, advantages, and limitations of femtosecond laser-assisted cataract surgery through a review of the literature. A PubMed search was conducted using topic-appropriate keywords to screen and select articles. Initial research has shown appropriate safety and efficacy of femtosecond laser-assisted cataract surgery, with improvements in anterior capsulotomy, phacofragmentation, and corneal incision. Limitations of these studies include small sample size and short-term follow-up. Cost-benefit analysis has not yet been addressed. Preliminary data for femtosecond laser-assisted cataract surgery shows appropriate safety and efficacy, and possible advantage over conventional cataract surgery. Questions to eventually be answered include comparisons of long-term postoperative complication rates-including infection and visual outcomes-and analysis of contraindications and financial feasibility.

  9. Cataract surgery to lower intraocular pressure

    Berdahl John

    2009-01-01

    Full Text Available Cataract and glaucoma are common co morbidities. Cataract surgery is frequently performed in patients with glaucoma. In this study, a review of literature with search terms of cataract, glaucoma and intraocular pressure is followed by evaluation and synthesis of data to determine the effect of cataract surgery on intraocular pressure. Cataract surgery seems to lower intraocular pressure on a sustained basis, especially in patients with higher preoperative intraocular pressure. The mechanism of action of these finds remains speculative.

  11. Surgery for Congenital Cataract

    David Yorston FRCS FRCOphth

    2004-01-01

    The management of congenital cataract is very different to the treatment of a routine age-related cataract. In adults, surgery may be delayed for years without affecting the visual outcome. In infants, if the cataract is not removed during the first year of life, the vision will never be fully regained after surgery. In adults, if the aphakia is not corrected immediately, it can be corrected later. In young children, if the aphakia is not corrected, the vision will never develop normally.

  14. Recovery after cataract surgery.

    Porela-Tiihonen, Susanna; Kokki, Hannu; Kaarniranta, Kai; Kokki, Merja

    2016-04-01

    Cataract surgery is the most common ophthalmological surgical procedure, and it is predicted that the number of surgeries will increase significantly in the future. However, little is known about the recovery after surgery. The first aim of this study was to evaluate the prevalence, severity and duration of pain and other ocular discomfort symptoms experienced after cataract surgery. The other objectives were to identify the factors associated with lower postoperative patient satisfaction and to measure the effect of cataract surgery on patients' health-related quality of life (HRQoL) and visual function in everyday life. The study design was a prospective follow-up study. The course of the recovery and the presence of ocular symptoms were evaluated by interviewing the patients via a questionnaire at 1 day, 1 week, 6 weeks and one year after surgery The visual functioning in everyday life was measured with Visual Functioning Index VF-7 and Catquest-9SF-questionnaires and furthermore the HRQoL was measured with the 15D-instrument before surgery and at 12 months after surgery. The patients returned the questionnaires by mail and were interviewed in the hospital on the day of the surgery. The same patients filled-in all the questionnaires. The patient reports were used to collect the data on medical history. A total of 303 patients were approached at Kuopio University Hospital in 2010-2011 and of these 196 patients were eligible and willing to participate, with postoperative data being available from 186 (95%) patients. A systematic review article was included in the study procedure and it revealed the wide range in the reported incidence of postoperative ocular pain. Some of the identified randomized controlled studies reported no or only minor pain whereas in some studies significant pain or pain lasting for several weeks has been described in more than 50% of the study patients. In the present study setting, pain was reported by 34% during the first

Of these 415 were phacoemulsification and 60 extracapsular and none received Intra...

  16. Femtosecond laser cataract surgery.

    Nagy, Zoltan Z; McAlinden, Colm

    2015-01-01

    Femtosecond laser (FSL) cataract surgery is in its infancy but is rapidly gaining popularity due to the improved consistency and predictability for corneal incisions and anterior capsulorhexis. It enables subsequently less phacoemulsification energy and time to be employed, which has gains in terms of reduced corneal oedema. In addition, the FSL allows better circularity of the anterior capsulotomy, capsule overlap, intraocular lens (IOL) placement and centration of the IOL. These advantages have resulted in improved visual and refractive outcomes in the short term. Complication rates are low which reduce with surgeon experience. This review article focuses on the Alcon LenSx system. PMID:26605364

  18. Cataract surgery and intraocular pressure.

    Melancia, Diana; Abegão Pinto, Luis; Marques-Neves, Carlos

    2015-01-01

    Cataract surgery is one of the most performed surgeries in the developed world. In addition to its significant impact on visual acuity, phacoemulsification has been hailed as a potential intraocular pressure (IOP)-lowering procedure. While current evidence suggests an overall significant and sustained decrease in IOP to exist after cataract surgery, the specific ocular characteristics that could help predict which patients are likely to benefit from this IOP-lowering effect remain unclear. This definition is important in glaucoma patients if this surgery is to be used in the treatment for this disease. Our review aims to summarize the literature on the subject, depicting possible mechanisms behind this IOP decrease, which type of patients are more likely to benefit from this surgery for IOP-lowering purposes and ultimately help optimizing disease management for the increasing number of patients with concomitant glaucoma and cataract.

  19. Viscoless microincision cataract surgery

    Guy Sallet

    2008-06-01

    Full Text Available Guy SalletDepartment of Opthamology, Aalsters Stedelijk Ziekenhuis, BelgiumAbstract: A cataract surgery technique is described in which incisions, continuous circular capsulorhexis and hydrodissection are made without the use of any viscoelastics. Two small incisions are created through which the different parts of the procedure can take place, maintaining a stable anterior chamber under continuous irrigation. Subsequent bimanual phacoemulsification can be done through these microincisions. At the end of the procedure, an intraocular lens can be inserted through the self-sealing incision under continuous irrigation. 50 consecutive cataract patients were operated on without the use of viscoelastics and then compared with a group of 50 patients who had been helped with viscoelastics. No difference in outcome, endothelial cell count or pachymetry was noted between the two groups. No intraoperative complication was encountered. Viscoless cataract surgery was a safe procedure with potential advantages.Keywords: ophthalmic visco-surgical device, viscoless cataract surgery, microincision

  1. Cataract Surgery Tool

    1977-01-01

    The NASA-McGannon cataract surgery tool is a tiny cutter-pump which liquefies and pumps the cataract lens material from the eye. Inserted through a small incision in the cornea, the tool can be used on the hardest cataract lens. The cutter is driven by a turbine which operates at about 200,000 revolutions per minute. Incorporated in the mechanism are two passages for saline solutions, one to maintain constant pressure within the eye, the other for removal of the fragmented lens material and fluids. Three years of effort have produced a design, now being clinically evaluated, with excellent potential for improved cataract surgery. The use of this tool is expected to reduce the patient's hospital stay and recovery period significantly.

Results: 106 eyes of 89 patients with uveitis were operated for cataract. In 62.3% eyes (66/106, post -operative follow-up was at least 6 months. There was significant improvement (P<0.001 in visual acuity after cataract surgery. Provided the uveitis was well controlled for three months pre-operatively, additional pre-operative anti-inflammatory medications did not significantly affect (P=0.842 post -operative inflammation. Patients who received extracapsular cataract extraction (ECCE or phacoemulsification with posterior chamber IOL (PCIOL obtained better visual acuity at 6 weeks (P=0.009 and P=0.032 respectively than those with only ECCE without IOL. In 37 eyes vision did not improve due to persistent uveitis (23.9%, 16/67, cystoid macular oedeme (20.9%, 14/67, and posterior capsule opacification (14.9%, 10/67. Conclusion: Cataract extraction and PCIOL implantation is safe in eyes with uveitis. Additional preoperative medications may not alleviate post-operative inflammation if uveitis is well controlled for at least three months before surgery.

    Bimanual microincisional cataract surgery has been introduced recently as a technique for cataract surgery and it is gaining interest of many cataract surgeons in the world. Over the last few years many changes were made in the phacoemulsification machines and the intraocular lenses design which allowed bimanual microincisional cataract surgery to be safer and more efficient. The purpose of this review is to introduce the technique of bimanual microincisional cataract surgery and to review al...

  4. Immediate Sequential Bilateral Cataract Surgery: A Systematic Review and Meta-Analysis

    Line Kessel

    2015-01-01

    Full Text Available The aim of the present systematic review was to examine the benefits and harms associated with immediate sequential bilateral cataract surgery (ISBCS with specific emphasis on the rate of complications, postoperative anisometropia, and subjective visual function in order to formulate evidence-based national Danish guidelines for cataract surgery. A systematic literature review in PubMed, Embase, and Cochrane central databases identified three randomized controlled trials that compared outcome in patients randomized to ISBCS or bilateral cataract surgery on two different dates. Meta-analyses were performed using the Cochrane Review Manager software. The quality of the evidence was assessed using the GRADE method (Grading of Recommendation, Assessment, Development, and Evaluation. We did not find any difference in the risk of complications or visual outcome in patients randomized to ISBCS or surgery on two different dates. The quality of evidence was rated as low to very low. None of the studies reported the prevalence of postoperative anisometropia. In conclusion, we cannot provide evidence-based recommendations on the use of ISBCS due to the lack of high quality evidence. Therefore, the decision to perform ISBCS should be taken after careful discussion between the surgeon and the patient.

    1984-01-01

    Despite the fact that two community-based surgeons switched from routine intracapsular cataract extraction to planned extracapsular cataract surgery and routine implantation of posterior chamber lenses, they did not materially increase the size of their surgical load or change their indications for cataract surgery. In contrast a similar change in surgical technique by two high-referral hospital-based surgeons was associated with a marked increase in operative rates and increased preoperative...

  14. Quality of vision in refractive and cataract surgery, indirect measurers: review article

    Taís Renata Ribeira Parede

    2013-12-01

    Full Text Available Visual acuity is the measurement of an individual's ability to recognize details of an object in a space. Visual function measurements in clinical ophthalmology are limited by factors such as maximum contrast and so it might not adequately reflect the real vision conditions at that moment as well as the subjective aspects of the world perception by the patient. The objective of a successful vision-restoring surgery lies not only in gaining visual acuity lines, but also in vision quality. Therefore, refractive and cataract surgeries have the responsibility of achieving quality results. It is difficult to define quality of vision by a single parameter, and the main functional-vision tests are: contrast sensitivity, disability glare, intraocular stray light and aberrometry. In the current review the different components of the visual function are explained and the several available methods to assess the vision quality are described.

  16. Complications of cataract surgery.

    Chan, Elsie; Mahroo, Omar A R; Spalton, David J

    2010-11-01

    Modern cataract surgery is safe in more than 95 per cent of patients. In the small number of cases where a serious complication occurs, the most common is an intra-operative posterior capsular rupture. This can lead to vitreous loss or a dropped nucleus and can increase the risk of post-operative cystoid macular oedema or retinal detachment. Post-operatively, posterior capsular opacification is the most common complication and can be readily treated with a YAG capsulotomy. The most devastating complication is endophthalmitis, the rate of which is now significantly decreased through the use of intracameral antibiotics. As a clinician, the most important step is to assess the patient pre-operatively to predict higher risk individuals and to counsel them appropriately. In these patients, various pre- or intra-operative management steps can be taken in addition to routine phacoemulsification to optimise their visual outcome. PMID:20735786

  18. Immediate versus Delayed Sequential Bilateral Cataract Surgery: A Systematic Review and Meta-Analysis.

    Monali S Malvankar-Mehta

    Full Text Available Immediately sequential bilateral cataract surgery (ISBCS, the cataract surgery that is performed in both eyes simultaneously, is gaining popularity worldwide compared to the traditional treatment paradigm: delayed sequential bilateral cataract surgery (DSBCS, the surgery that is performed in each eye on a different day as a completely separate operation. ISBCS provides advantages to patients and patients' families in the form of fewer hospital visits. Additionally, patients enjoy rapid rehabilitation, lack of anisometropia - potentially reducing accidents and falls, and avoid suboptimal visual function in daily life. The hospital may benefit due to lower cost.To perform a systematic review and meta-analysis to evaluate ISBCS and DSBCS.Databases including MEDLINE, EMBASE, BIOSIS, CINAHL, Health Economic Evaluations Database (HEED, ISI Web of Science (Thomson-Reuters and the Cochrane Library were searched.Not applicable.Literature was systematically reviewed using EPPI-Reviewer 4 gateway. Meta-analysis was conducted using STATA v. 13.0. Standardized mean difference (SMD and 95% confidence intervals (CI were calculated and heterogeneity was assessed using I2 statistics. Fixed-effect and random-effect models were computed based on heterogeneity. Meta-analysis was done by instrument used to calculate utility score.In total, 9,133 records were retrieved from multiple databases and an additional 128 records were identified through grey literature search. Eleven articles with 3,657 subjects were included for analysis. Our meta-analysis results indicated significant improvement in post-operative utility score using TTO, EQ5D, HUI3, VF-7, and VF-14 and a non-significant improvement using Catquest questionnaire for both surgeries. For ISBCS versus DSBCS, utility-specific fixed-effect model provided an overall SMD of the utility score using the TTO method as 0.12 (95% CI: -0.15, 0.40, EQ5D as 0.14 (95% CI: -0.14, 0.41, HUI3 as 0.12 (95% CI: -0.15, 0.40, VF

  19. Heavier molecular weight ocular viscoelastic devices and timing of post-operative review following cataract surgery

    Brooker Lucenne

    2007-02-01

    Full Text Available Abstract Background To assess the safety of abandoning the next day post-operative review in preference for assessment only 2 hours post-surgery for both phacoemulsification and extracapsular surgery with heavier molecular weight ocular viscoelastic devices (OVD. Methods 475 patients who underwent uncomplicated cataract surgery using heavier molecular weight ocular viscoelastic device (Healon GV were studied. Of these 415 were phacoemulsification and 60 extracapsular and none received Intraocular pressure (IOP lowering prophylaxis at the end of surgery. All were examined at 2 hours post-surgery and on the following day. Results were tabulated and analysed assessing wound stability, corneal clarity, anterior chamber reaction and IOP. Results In the time between the two assessments 44 (10.6% patients developed a total of 53 new problems, with a majority being increases in IOP. Based on the lower threshold of IOP of 30 mmHg, the incidence of new problems at the next-day assessment was 9.8% (95% CI: 7.0 to 13.6 in the phacoemulsification group and 16.3% (7.3 to 29.7in the extracapsular surgery group. At the higher threshold of IOP of 35 mmHg the corresponding figures were 6.6% and 16.3%. Conclusion There is a higher incidence of new problems at the next-day assessment than previous studies with conventional OVD. Therefore results from previous studies using standard OVDs cannot be simply extrapolated to heavier molecular weight OVDs. When these agents are used, routine use of an ocular hypotensive agent may be necessary to increase the safety of abandoning the review on the first post-operative day for phacoemulsification patients. This is to be studied.

  20. EARLY COMPLICATIONS OF CATARACT SURGERY

    C. Constantin

    2013-06-01

    Full Text Available BACKGROUND: There are different complications of the cataract surgery described in the literature. The impact of these complications on the visual function is in correlation with many factors, some of them being imprecise and unable to be used as prognostic factors before and after the surgery. The modern technique and the surgeon’s experience lowers the complications incidence to a minimum, but even so, some problems cannot be avoided. AIM: The aim of this study is to analyse the early cataract surgery complications for patients operated in 2012 at the Ophthalmology Unit, Railway Hospital, Iaşi. MATERIAL AND METHOD: We conducted a retrospective analysis of the medical records of the patients who underwent cataract surgery in 2012. There were a total of 480 cataract surgeries, the majority of them (92,7% being age related cataracts in different stages of evolution, of which 31.45% being mature cataracts. In 476 eyes, artificial lens was inserted per-primam (474 eyes with posterior chamber intraocular lens and 2 eyes with anterior chamber intraocular lens, in one case the posterior chamber intraocular lens was sutured to the sclera, in 3 cases the eyes remained without lens. RESULTS: The incidence of severe complications or with potential of severe development was: severe corneal oedema 0.83% (4 cases, remaining lens fragments in the vitreous cavity 0.62% (3 cases, toxic anterior segment syndrome (TASS 0.41% (2 cases. There were no endophthalmitis, expulsive haemorhage or retinal detachment after cataract surgery. CONCLUSIONS: The number of early complications of our patients is the same with numbers shown in other studies. With a better surgical technique, a good examination of the patient, a thorough explanation of the procedure to the patient, the use of high quality substances during surgery and proper technology we can lower even more the incidence of the complications.

  1. Cataract surgery in pseudoexfoliation syndrome.

    Sangal, Neha; Chen, Teresa C

    2014-01-01

    Pseudoexfoliation (PXF) syndrome is characterized by the deposition of distinctive fibrillar material in the anterior segment of the eye. It is an age-related process that is associated with open and narrow angle glaucomas and the formation of cataracts. Not only is PXF associated with the formation of dense nuclear cataracts, it is also well known that those presenting with PXF are at a higher risk of developing complications during, and even after, cataract surgery. Complications associated with cataract surgery in PXF can occur from poor pupillary dilation, zonular weakness leading to intraoperative or postoperative lens dislocation and vitreous loss, postoperative intraocular pressure (IOP) spikes potentiating glaucomatous damage, capsular phimosis, prolonged inflammation, and postoperative corneal decompensation. The surgeon should be prepared to encounter the various potential intraoperative and postoperative complications in eyes with pseudoexfoliation syndrome during cataract surgery. In this way, the surgeon can plan his/her surgical technique to help avoid surprises during cataract surgery and be prepared to manage the potential postoperative complications that can occur in pseudoexfoliation eyes.

    2016-06-01

    This study aimed to investigate the prevalence and clinical determinants of cataract and cataract surgery in Korean population. The 2008-2012 Korean National Health and Nutrition Examination Survey was analyzed, which included 20,419 participants aged ≥ 40 years. The survey is a multistage, probability-cluster survey, which can produce nationally representative estimates. Prevalence of cataract and cataract surgery was estimated. Clinical determinants for those were investigated using logistic regression analyses (LRAs). The prevalence of cataract was 42.28% (95% confidence interval [CI], 40.67-43.89); 40.82% (95% CI, 38.97-42.66) for men and 43.62% (95% CI, 41.91-45.33) for women (P = 0.606). The prevalence of cataract surgery was 7.75% (95% CI, 7.30-8.20); 6.38% (95% CI, 5.80-6.96) for men and 9.01% (95% CI, 8.41-9.61) for women (P Cataract was associated with older age (P Cataract surgery was consistently associated with older age, occupation, DM, asthma, and anemia in two LRAs, which compared participants with cataract surgery to those without cataract surgery and those having a cataract but without any cataract surgery, respectively. Hypertension, arthritis, and dyslipidemia were associated with cataract surgery at least in one of these LRAs. These results suggest that there are 9.4 million individuals with cataract and 1.7 million individuals with cataract surgery in Korea. Further studies are warranted to reveal the causality and its possible mechanism of developing/exacerbating cataract in novel determinants (i.e., anemia, asthma, and arthritic conditions) as well as well-known determinants.

  3. [Keratoplasty combined with cataract surgery].

    Muraine, M; Gueudry, J; Retout, A; Genevois, O

    2012-09-01

    Corneal pathologies leading to keratoplasty are often associated with cataract and combined surgery is therefore mandatory. Triple procedure with penetrating keratoplasty and concurrent cataract extraction followed by intra ocular lens (IOL) implantation is usually the preferential choice because visual rehabilitation is theoretically more rapid. Surgeons have to be aware of surgical conditions during open-sky surgery because vitreous pressure is not counterbalanced by anterior chamber pressure. Today, many surgeons prefer non-simultaneous procedures with cataract surgery performed months after grafting because of the improvement in spherical refractive error. More recently, new triple procedures, Descemet's stripping automated keratoplasty and concurrent cataract surgery have gained popularity, especially in patients with Fuchs dystrophy associated with cataract. Surgery starts with phacoemulsification, followed by endothelium exchange through a 3 to 5 mm incision. Advantages against classic triple procedure are quick visual rehabilitation, fewer induced refractive errors, minimal postoperative discomfort and corneal integrity. Surgeons have to consider an eventual postoperative hyperopic shift secondary to corneal lenticule shape when choosing adequate intraocular lens. PMID:22921023

    PURPOSE: To determine the long-term risk of retinal detachment following pediatric cataract surgery and to identify risk factors for retinal detachment. METHODS: We included all children (aged 0 to 17 years) who during the time period of 1977 to 2005 underwent pediatric cataract surgery in Denmark...... was based on medical chart review. RESULTS: Among 1043 eyes of 656 children undergoing surgery for pediatric cataract, 25 eyes (23 children) developed retinal detachment at a median time of 9.1 years after surgery. The overall 20-year risk of retinal detachment was 7% (95% confidence interval [CI]: 3...... (16% [95% CI: 6%-24%]). CONCLUSIONS: The estimated overall risk of retinal detachment 20 years after pediatric cataract surgery was 7%, but only 3% for isolated cataract. Particularly high risks of retinal detachment after cataract surgery were associated with mental retardation and having other...

  7. CATARACT SURGERY IN PSEUDOEXFOLIATION SYNDROME

    Abbin George

    2014-10-01

    Full Text Available Pseudoexfoliation (PEX syndrome is an age-related systemic disorder with major ocular manifestations. It is characterized by the production and deposition of fibrillogranular amyloid-like extracellular material within many ocular tissues. Pseudoexfoliation is also a risk factor for glaucoma and also correlated to an increased incidence of cataract formation. Cataract surgery in eyes with pseudoexfoliation is connected with many complications and presents challenges that require careful preoperative planning and intraoperative care to ensure safe surgery and successful postoperative outcome. Zonular weakness and poor pupillary dilation are the two major risk factors for surgical complications and poor visual acuity after surgery. With proper preparation and the use of specialized adjunctive devices, phacoemulsification is the preferred procedure of cataract extraction in this group of patients. Postoperatively, patients require frequent and detailed follow-up to monitor for complications such as intraocular pressure rise, inflammation and intraocular lens dislocation. In conclusion, with appropriate preoperative, intraoperative and postoperative care, the risk of complications can be minimized and favorable outcomes may be achieved in cataract surgery in eyes with pseudoexfoliation syndrome.

  8. Clear corneal incision in cataract surgery

    Ammar M Al Mahmood

    2014-01-01

    Full Text Available Since the introduction of sutureless clear corneal cataract incisions, the procedure has gained increasing popularity worldwide because it offers several advantages over the traditional sutured scleral tunnels and limbal incisions. Some of these benefits include lack of conjunctival trauma, less discomfort and bleeding, absence of suture-induced astigmatism, and faster visual rehabilitation. However, an increasing incidence of postoperative endophthalmitis after clear corneal cataract surgery has been reported. Different authors have shown a significant increase up to 15-fold in the incidence of endophthalmitis following clear corneal incision compared to scleral tunnels. The aim of this report is to review the advantages and disadvantages of clear corneal incisions in cataract surgery, emphasizing on wound construction recommendations based on published literature.

    Kessel, Line; Andresen, Jens; Erngaard, Ditte; Flesner, Per; Tendal, Britta; Hjortdal, Jesper

    2016-02-01

    The need for cataract surgery is expected to rise dramatically in the future due to the increasing proportion of elderly citizens and increasing demands for optimum visual function. The aim of this study was to provide an evidence-based recommendation for the indication of cataract surgery based on which group of patients are most likely to benefit from surgery. A systematic literature search was performed in the MEDLINE, CINAHL, EMBASE and COCHRANE LIBRARY databases. Studies evaluating the outcome after cataract surgery according to preoperative visual acuity and visual complaints were included in a meta-analysis. We identified eight observational studies comparing outcome after cataract surgery in patients with poor (20/40) preoperative visual acuity. We could not find any studies that compared outcome after cataract surgery in patients with few or many preoperative visual complaints. A meta-analysis showed that the outcome of cataract surgery, evaluated as objective and subjective visual improvement, was independent on preoperative visual acuity. There is a lack of scientific evidence to guide the clinician in deciding which patients are most likely to benefit from surgery. To overcome this shortage of evidence, many systems have been developed internationally to prioritize patients on waiting lists for cataract surgery, but the Swedish NIKE (Nationell Indikationsmodell för Katarakt Ekstraktion) is the only system where an association to the preoperative scoring of a patient has been related to outcome of cataract surgery. We advise that clinicians are inspired by the NIKE system when they decide which patients to operate to ensure that surgery is only offered to patients who are expected to benefit from cataract surgery.

  16. Femtosecond laser cataract surgery: technology and clinical practice.

    Roberts, Timothy V; Lawless, Michael; Chan, Colin Ck; Jacobs, Mark; Ng, David; Bali, Shveta J; Hodge, Chris; Sutton, Gerard

    2013-03-01

    The recent introduction of femtosecond lasers to cataract surgery has generated much interest among ophthalmologists around the world. Laser cataract surgery integrates high-resolution anterior segment imaging systems with a femtosecond laser, allowing key steps of the procedure, including the primary and side-port corneal incisions, the anterior capsulotomy and fragmentation of the lens nucleus, to be performed with computer-guided laser precision. There is emerging evidence of reduced phacoemulsification time, better wound architecture and a more stable refractive result with femtosecond cataract surgery, as well as reports documenting an initial learning curve. This article will review the current state of technology and discuss our clinical experience. PMID:22788831

Its incidence can be reduced by means of antibiotic prophylaxis. Although the prophylactic use of intracameral cefuroxime has been extended, other drugs, such as moxifloxacin, have arisen as alternatives. We performed a systematic literature review on the effectiveness and efficiency of intracameral cefuroxime and moxifloxacin for the prophylaxis of postoperative endophthalmitis after cataract surgery. Several bibliographic databases were searched up to October 2010 and were updated up to January 2013. Outcomes were the onset of endophthalmitis after surgery and the cost-effectiveness ratio of using both antibiotic prophylaxis alternatives. The following were included: a clinical trial reported in two papers, six observational studies, and an economic evaluation. All studies assessed cefuroxime compared with another antibiotic prophylaxis or no prophylaxis. The only randomized controlled trial performed by the European Society of Cataract and Refractive Surgery found that intracameral cefuroxime is significantly more effective than not using prophylaxis or the use of a topical antibiotic. The observational studies support these results. The economic evaluation compared different prophylaxis regimens and concluded that intracameral

    Full Text Available Purpose: To determine the incidence and risk factors associated with glaucoma following congenital cataract surgery (CCS in children under age of 15 Methods: This prospective cohort (since 2006 consisted of children less than 15 years of age who underwent cataract surgery with or without intraocular lens (IOL implantation. The role of the following factors on the development of glaucoma after CCS including age at surgery, gender, laterality of the cataract, IOL implantation, congenital ocular anomalies, intra- and postoperative complications, length of follow-up, central corneal thickness (CCT as well as the effect of the age of onset, time to development of glaucoma, and response to treatment were evaluated. Results: Overall, 161 eyes of 96 patients were included in this study of which 28 eyes developed glaucoma. Incidence of glaucoma was 17.4%. Mean±SD age at surgery was 9.3±6.9 (range, 1-24 months in glaucomatous and 40.4±41.1 (range, 1 m-13.6 year months in non-glaucomatous group (p<0.001. All glaucoma patients had the operation under two years of age. In group 1, 9 (60% and in group 2, 24 (30% patients were female (p=0.001. In group 1, 17 eyes (60.7% and in the group 2, 41 eyes (30.8% were aphakic (p=0.001. Mean time to diagnosis of glaucoma was 111.2 days (range 30-1200 days. Mean follow-up time was 3.1 years (range, 1-6 years. In 22 (78.6% eyes glaucoma was diagnosed within six months after surgery. Glaucoma was controlled with medications in 23 eyes (82% and with surgery in five eyes. Conclusion: In this study the incidence of glaucoma after CCS was 17.4% over a follow-up period of six years. Younger age at the time of lensectomy increases the risk of secondary glaucoma. IOL implantation may protect against glaucoma. Female gender was affected more than male.

  7. Cataract surgery after Descemet stripping endothelial keratoplasty

    Sunita Chaurasia

    2012-01-01

    Full Text Available Management of endothelial dysfunction in phakic patients is sometimes a dilemma for corneal surgeons. Phakic patients with visually significant cataract and endothelial dysfunction are preferably managed by performing combined cataract surgery with endothelial keratoplasty. However, combined surgery may be deferred in eyes with early incipient cataract, younger age and where anterior chamber is poorly visualized. As cataract formation may be accelerated after endothelial keratoplasty, these eyes may need cataract surgery subsequently. Surgical intervention in eyes with endothelial keratoplasty is of concern as this may affect the graft adversely and threaten graft survival. In this report, we describe the intraoperative surgical details and postoperative clinical course of a patient who underwent phacoemulsification with intraocular lens implantation after Descemet stripping automated endothelial keratoplasty (DSAEK.

    Full Text Available PURPOSE: To assess the safety and efficacy of Manual Small Incision Cataract Surgery (MSICS in cases of white cataract with the use of trypan blue as an adjunct for performing continuous curvilinear capsulorthexis (CCC. MATERIALS AND METHODS: Prospective observational study on 100 consecutive eyes of 100 patients with white cataract who had undergone MSICS with trypan blue assisted CCC. The nucleus was prolapsed into anterior chamber by using a sinskey hook and extracted out of the eye using irrigating vectis. Intraoperative and postoperative findings (according to OCTET classification as well as postoperative visual outcomes were used as main measures to report the safety and efficacy of the surgery. RESULTS: Of the 100 eyes, 16 had intumescent, 67 had mature and 17 had hypermature cataract. Intraoperatively CCC was incomplete in 4 eyes (4% and had to be converted to canopener capsulotomy. None of the eyes had posterior capsular rupture or zonular dialysis and no eyes were converted to conventional Extra Capsular Cataract Extraction (ECCE. Postoperatively, 6 eyes (6% developed corneal oedema with >10 Descemets folds and 7 eyes (7% had corneal oedema with < 10 Descemets folds. Mild iritis was seen in 6 eyes (6% and moderate iritis with fibrin membrane was seen in 3 eyes (3%. Iridodialysis was observed in 1 eye (1%. Of the 99 patients (99% categorised under good visual outcomes category, 94 patients (94% had a best-corrected visual acuity of 6/9 or better on the 40th post-operative day. CONCLUSION: In developing countries like India where phacoemulsification may not be affordable to a majority of those requiring cataract surgery, MSICS proves to be a safe and efficacious alternative for white cataracts especially with the adjunctive use of trypan blue dye.

  15. Intraocular lens employed for cataract surgery

    Roszkowska, A. M.; Torrisi, L.

    2014-04-01

    The aim of this paper is to illustrate the techniques of cataract surgery with implantation of intraocular lenses and some physical properties of the used materials. The new technology, coupled with extensive experience and the studied cases, permits to increase the standardization and accuracy of the engravings, by reducing the use and handling of surgical instruments inside the eye. At present it is possible to replace the cataract with crystalline lenses based on biopolymers such as PMMA, silicone, acrylic hydrophilic and hydrophobic acrylic. These materials are increasingly able to replace the natural lens and to ensure the fully functional of the eye. The role of femtosecond lasers in cataract surgery, to assist or replace several aspects of the manual cataract surgery, are discussed.

    Drexler, Wolfgang; Findl, Oliver; Menapace, Rupert; Hitzenberger, Christoph K.; Fercher, Adolf F.

    1999-02-01

    In an earlier study we showed that precise axial eye length measurement on cataract eyes is possible with the dual beam partial coherence interferometry technique (PCI). A high correlation with the standard ultrasound technique has been obtained. Recently, in a prospective study, partially coherent interferometry and ultrasound biometry were compared in cataract surgery using the SRK II formula based on US applanation biometry. Three months after surgery PCI was repeated and refractive outcome was determined. The use of PCI would have improved refractive outcome by about 30%.

    Nagy ZZ

    2014-06-01

    Full Text Available Zoltan Z NagyDepartment of Ophthalmology, Semmelweis University, Budapest, HungaryAbstract: Femtosecond lasers represent a new frontier in cataract surgery. Since their ­introduction and first human treatment in 2008, a lot of new developments have been achieved. In this review article, the physical principle of femtolasers is discussed, together with the indications and side effects of the method in cataract surgery. The most important clinical results are also presented regarding capsulotomy, fragmentation of the crystalline lens, corneal wound creation, and refractive results. Safety issues such as endothelial and macular changes are also discussed. The most important advantage of femtolaser cataract technology at present is that all the important surgical steps of cataract surgery can be planned and customized, delivering unparalleled accuracy, repeatability, and consistency in surgical results. The advantages of premium lenses can be maximally used in visual and presbyopia restoration as well. The advantages of ­premium lenses can be maximally used, not only in visual, but in presbyopia restoration as well. Quality of vision can be improved with less posterior chamber lens (PCL tilt, more centralized position of the PCL, possibly less endothelial damage, less macular edema, and less posterior capsule opacification (PCO formation. This technological achievement should be followed by other technical developments in the lens industry. Hopefully this review article will help us to understand the technology and the results to ­demonstrate the differences between the use of femtolasers and phacoemulsification-based cataract surgery. The most important data of the literature are summarized to show ophthalmologists the benefits of the technology in order to provide the best refractive results to the patient.Keywords: femtosecond laser-assisted cataract surgery, capsulotomy, lens fragmentation, corneal wound, arcuate keratotomy, safety

  8. Dropped nucleus following phacoemulsification cataract surgery.

    Tajunisah, I; Reddy, S C

    2007-12-01

    Twenty two cases of dropped nucleus following 1,196 phacoemulsification procedures in cataract surgery were examined retrospectively to determine the incidence, predisposing factors and visual outcomes of this dreaded complication. All the cases underwent pars plana vitrectomy and the lens fragments were removed with phacofragmotome, vitrectomy cutter or delivered through limbus. The incidence of dropped nucleus was 1.84%. The predisposing factors were hard cataracts (13.6%), polar cataracts (9.1%), previously vitrectomized eyes (4.5%) and high myopia (4.5%). The final visual outcome was > or = 6/12 in 10 eyes (45.5%); complications were seen in 5 eyes (22.7%). The interval between initial surgery and vitrectomy, the method of fragment removal and the type of lens implanted, did not influence the final visual outcome. PMID:18705466

  9. [The development of cataract surgery after 1745].

    Pouw, C A M Karin; Zegers, Richard H C

    2013-01-01

    Nowadays, cataract surgery is the most commonly performed surgical procedure in the Netherlands. This is due to the increasing incidence of cataracts, the changing indication for surgery in our society where good vision is becoming increasingly important, and the quality of the operation. How was this modern procedure developed? Cataracts were treated by couching until the middle of the 18th century. Since then, many discoveries by a number of doctors changed the procedure gradually from couching to lens extraction and through extracapsular to intracapsular extraction with the simultaneous implantation of an intraocular lens. This article outlines the development and also discusses some of the many inventions in the field of instrumentation and materials that have brought this intervention to its current high level; these include the cryo-probe, implantation of artificial lenses, the use of hyaluronic acid, phaco-emulsification, smaller incisions without sutures and the development of foldable intraocular lenses.

The KAMRA™ small aperture inlay was the first such inlay to receive Conformité Européenne (CE marking in 2005. It has been shown to improve uncorrected near and intermediate visual acuity without adversely affecting uncorrected distance visual acuity. Due to the age of presbyopic patients, they may eventually develop cataracts. In two such cases, we found that cataract surgery with the KAMRA implant left in place was not technically more difficult, and that the surgical procedure could be improved by additional ocular rotations to improve visualization. Biometry readings were reliable, and it appeared that the SRK/T formula was accurate for calculation of intraocular lens power. Cataract surgery with the KAMRA implant left in situ is a viable option for patients. Keywords: cataract surgery, KAMRA, corneal inlay, AcuTarget, presbyopia

  14. Tools to fight the cataract epidemic: A review of experimental animal models that mimic age related nuclear cataract.

    Lim, Julie C; Umapathy, Ankita; Donaldson, Paul J

    2016-04-01

    Cataract is the leading cause of blindness worldwide and accounts for approximately half of all forms of vision loss. Currently, the only way to treat cataracts is by surgery. However, with an ageing population, the demand for surgery and the need for cost effective alternative solutions grows exponentially. To reduce the need for cataract surgery, alternative medical therapies to delay cataracts are urgently required. However, given the difficulty in accessing human cataract lenses, investigating the process of cataract formation and testing the efficacy of potential therapies in humans is problematic. Therefore, researchers have looked to create suitable animal models of cataractogenesis to identify therapeutic options. This review will provide an overview of the cataract specific changes previously reported in human cataract lenses, before focussing on the specific changes that occur in age related nuclear (ARN) cataract, the most common form of cataract in humans. This will be followed by a discussion of a range of existing animal cataract models and their respective suitability for mimicking the processes associated with the development of ARN cataract, and therefore their utility as models to test anti-cataract therapies for future use in humans.

  15. Axial length variability in cataract surgery

    To determine the mean axial length and biometric measures in patients undergoing cataract surgery and further compare the variability of axial length between the gender and with age. Study Design: Cross-sectional observational study. Place and Duration of Study: Eye Unit I, Department of Ophthalmology, Liaquat University of Medical and Health Sciences, Hyderabad, Pakistan from January 2010 to December 2012. Methodology: All patients referred for cataract surgery were assessed. The study included 886 eyes which were straightforward cataract cases with no other ocular problem. The data was collected for axial length, keratometric values and Intra-Ocular Lens (IOL) power prior to cataract surgery. The collected data was then analyzed using SPSS version 19 for windows software. Results: Gender based comparison showed significant difference in age, axial length, keratometric values and IOL power between the two groups (p=0.000). 86% of the eyes had an axial length between 21.00 mm and 23.99 mm. In univariate analysis there was significant (p=0.000) relation between overall age and axial length. The keratometric values ranged between 36.75 D and 52.50 D. Majority of the IOL powers ranged between 20.00 D and 23.00 D. Conclusion: The mean axial length of patients undergoing cataract surgery was 22.96 +- 1.04 mm, was comparable to Indian and Chinese population but shorter than the Western population. Females had shorter axial lengths, similar to other studies. Axial length was positively associated with age among the females, the cause of which is yet to be determined. (author)

  1. The clinical utility of new combination phenylephrine/ketorolac injection in cataract surgery

    Lawuyi LE

    2015-07-01

    Full Text Available Lola Elizabeth Lawuyi, Avinash Gurbaxani Moorfields Eye Hospital Dubai, Dubai, UAE Abstract: The maintenance of mydriasis throughout cataract extraction surgery and the control of ocular inflammation are crucial for successful surgical outcomes. The development of miosis during cataract surgery compromises the visualization of the surgical field and working space for surgeons. This may lead to complications that include posterior capsular tear and associated vitreous loss, longer surgical time, and postoperative inflammation. Postoperative inflammation is often uncomfortable and frustrating for patients. It causes pain, redness, and photophobia. This compromises the best-uncorrected vision following surgery and often leads to multiple clinic visits. This article examines the literature published on the current treatments used to manage mydriasis, pain, and inflammation in cataract extraction surgery. Combination phenylephrine/ketorolac injection offers an exciting new class of medication for use in cataract surgery. With the recent approval of Omidria™ (combination of phenylephrine 1% and ketorolac 0.3% by the US Food and Drug Administration (FDA for intraocular use, we review the clinical utility of this new combination injection in cataract surgery. PubMed, MEDLINE, and conference proceedings were searched for the relevant literature using a combination of the following search terms: cataract extraction surgery, pupil dilation (mydriasis, miosis, phenylephrine, ketorolac, Omidria™, intracameral mydriatic. Relevant articles were reviewed and their references checked for further relevant literature. All abstracts were reviewed and full texts retrieved where available.

    Lam, Dennis; Rao, Srinivas K; Ratra, Vineet; Liu, Yizhi; Mitchell, Paul; King, Jonathan; Tassignon, Marie-José; Jonas, Jost; Pang, Chi P; Chang, David F

    2015-01-01

    Cataract is the leading cause of reversible blindness and visual impairment globally. Blindness from cataract is more common in populations with low socioeconomic status and in developing countries than in developed countries. The only treatment for cataract is surgery. Phacoemulsification is the gold standard for cataract surgery in the developed world, whereas manual small incision cataract surgery is used frequently in developing countries. In general, the outcomes of surgery are good and complications, such as endophthalmitis, often can be prevented or have good ouctomes if properly managed. Femtosecond laser-assisted cataract surgery, an advanced technology, can automate several steps; initial data show no superiority of this approach over current techniques, but the results of many large clinical trials are pending. The greatest challenge remains the growing 'backlog' of patients with cataract blindness in the developing world because of lack of access to affordable surgery. Efforts aimed at training additional cataract surgeons in these countries do not keep pace with the increasing demand associated with ageing population demographics. In the absence of strategie that can prevent or delay cataract formation, it is important to focus efforts and resources on developing models for efficient delivery of cataract surgical services in underserved regions.

    Full Text Available Pur po se: To determine the tear osmolarity changes in patients who had undergone phacoemulsification surgery. Ma te ri al and Met hod: Tear osmolarity measurements were performed in 30 eyes of 30 patients who had undergone cataract surgery without any complication. Measurements were performed before surgery and consecutively at 1st month, 3rd month, and 6th month after the surgery. TearLab osmometer (TearLab Corporation, San Diego, CA, USA device was used for the measurements and paired ttest was used for statistical analysis. Re sults: The mean age of the patients was 72.3±3.7 (67-78 years. Thirteen patients were men and 17 patients were women. The mean osmolarity values were 305.8±6.5 mOsm/L before the surgery and 312.3±6.4 mOsm/L at 1st month, 307.5±5.1 mOsm/L at 3rd month and 305.1±5.7 at 6th month after the surgery. The difference between the values before surgery and at 1st month was found statistically significant (p=0.001. Dis cus si on: The tear osmolarity increases at the first month after surgery but decreases to the levels measured before surgery at the 3rd month. The increase at the first month may be due to the corneal incisions and medication used after the surgery. We think that we have to take into account this similarity increase in all cataract patients, especially in those who also have dry eye disease. (Turk J Ophthalmol 2012; 42: 35-7

    2016-01-01

    Purpose. This study retrospectively analyzed cataract surgeries to examine the usefulness of Surgical Media Center (SMC) (Abbott Medical Optics Inc.), a new cataract surgery recording device, for training of cataract surgery. Methods. We studied five hundred cataract surgeries conducted with a phacoemulsification system connected to the SMC. After surgery, the surgical procedures were reviewed, with changes in aspiration rate, vacuum level, and phaco power displayed as graphs superimposed on the surgical video. We examined whether use of SMC is able to demonstrate the differences in technique between experienced and trainee operators, to identify inappropriate phacoemulsification techniques from analyzing the graphs, and to elucidate the cause of intraoperative complications. Results. Significant differences in the time taken to reach maximum vacuum and the speed of increase in vacuum during irrigation and aspiration were observed between experienced and trainee operators. Analysis of the graphs displayed by SMC detected inappropriate phacoemulsification techniques mostly in cases operated by trainee operators. Conclusions. Using SMC, it was possible to capture details of cataract surgery objectively. This recording device allows surgeons to review cataract surgery techniques and identify the cause of intraoperative complication and is a useful education tool for cataract surgery. PMID:26881060

  12. How to prevent endophthalmitis in cataract surgeries?

    Kelkar Aditya

    2008-01-01

    Full Text Available Postoperative endophthalmitis is a very devastating complication and every step should be taken to reduce its occurrence. Unattended air conditioning filter systems are often the culprits and regular maintenance of the filters is of paramount importance. Shedders of pathogenic organisms amongst the theater personnel should be identified by regular screening and should be promptly treated. In addition to the use of Povidone iodine 5% solution in the conjunctival sac few minutes prior to surgery, proper construction of wound, injectable intraocular lenses, use of prophylactic intracameral antibiotics or prophylactic subconjunctival antibiotic injection at the conclusion of cataract surgery, placing a patch after the surgery for at least 4 h and initiating topical antibiotics from the same day of surgery helps to lower the frequency of postoperative endophthalmitis. Intraoperative posterior capsule rupture and anterior vitrectomy are risk factors for acute endophthalmitis, and utmost care to prevent posterior capsular rent should be taken while performing cataract surgery. Also, in case of such complication, these patients should be closely monitored for early signs of endophthalmitis in the postoperative period. In the unfortunate event of endophthalmitis the diagnosis should be prompt and treatment must be initiated as early as possible.

    2004-01-01

    Full Text Available Cataract surgery is most common in human surgery and comprises 80% of eye surgery programs. Owing to sophisticated technologies, it has become a routine surgery with lowered complications rate; hence, the functional outcome is more conditioned by operative trauma. The aim of this study was to demonstrate the significance of specular microscopy in the evaluation of operative trauma during extra-capsular cataract extraction (ECCE and phacoemulsification (P, in a controlled environment. The study included 100 consecutive patients who met the established criteria, and groups were formed according to the type of surgery by the assignment of successive numbers from a random number table. Examination and photographs of the corneal endothelium, as well as pachymetry were performed on Keeler-Konan Poclington Specular Microscope (KSP. The obtained results revealed significant dissimilarity in endothelial cell reduction (9.17% in group E, and 4.72% in group P, which generated statistically significant correlation of pre-operative and post-operative pachymetry in the group E (p=0.0004. On the basis of the results obtained by specular microscopy, it was concluded that under the same conditions phacoemulsification caused reduced operative trauma of the corneal endothelium.

  18. [Objective evaluation the application of femtosecond laser in cataract surgery].

    Liu, Y Z

    2016-02-11

    Femtosecond laser-assisted cataract surgery (FLACS) is a novel technology and the biggest revolution in the field of cataract in the latest several years. However, increasing large-scale population randomized controlled trials (RCT) have demonstrated that FLACS does not provide significant advantages over conventional phacoemulsification cataract surgery (CPCS) for common cataract patients. Furthermore, the cost and space requirement of the femtosecond equipment are another two limitations for the universal application of FSL in cataract surgery. However, FLACS may be beneficial for complex cataract situations, such as lens dislocation, zonular laxity, traumatic cataract, low preoperative endothelial cell values, and significant corneal astigmatism. With the progress of science and technology, FLACS can be expected to achieve integration with phacoemulsification systems, and equipment costs can be reduced, making it more widely used in clinical practice in the future.

    Full Text Available Jonathan S Chang, Harry W Flynn Jr, Darlene Miller, William E Smiddy Department of Ophthalmology, Bascom Palmer Eye Institute, Miller School of Medicine, University of Miami, Miami, FL, USA Background: Stenotrophomonas maltophilia is a Gram-negative organism known to cause opportunistic infections. It is a rare source of endophthalmitis, often in the setting of trauma, but has been reported following cataract extraction. The purpose of this study was to evaluate antimicrobial sensitivities, clinical characteristics, and treatment outcomes in patients with endophthalmitis caused by S. maltophilia following cataract extraction. Methods: A retrospective case review of records from January 1, 1990 to June 30, 2010 was performed at the Bascom Palmer Eye Institute. Results: Eight cases of S. maltophilia endophthalmitis were identified following cataract surgery. Initial visual acuity ranged from 20/200 to light perception. Time to diagnosis with cultures was 2–118 days. Patients received either intravitreal tap and inject (n = 5 or pars plana vitrectomy with intravitreal antibiotic injections (n = 3. All patients had vitreous or anterior chamber cultures positive for S. maltophilia. Seven of seven isolates tested were found to be sensitive to ceftazidime. Seven of eight isolates were sensitive to polymyxin B, six of eight isolates were sensitive to amikacin, and five of the seven isolates tested were sensitive to ciprofloxacin. Two of four tested isolates were sensitive to trimethoprim-sulbactam. All eight isolates were resistant to gentamicin and seven of the seven tested isolates were resistant to imipenem. All patients received intravitreal ceftazidime as part of the initial treatment regimen. Final visual acuity ranged from 20/25 to 4/200. Conclusion: S. maltophilia endophthalmitis is a rare source of endophthalmitis following cataract surgery. A case series of eight independent patients is reported, along with antibiotic resistance profiles and

  6. [Developments in modern cataract surgery – a critical overview].

    Menapace, Rupert

    2016-01-01

    Cataract surgery has tremendously evolved in recent years. Innovations include micro-incision cataract surgery through incisions smaller than 2mm, high-fluidics phacoaspiration and laser phacoemulsification to minimize or replace the use of ultrasound, the advent of femtolasers for high-precision incisions in the cornea, the lens capsule and the cataractous lens, aspheric intraocular lenses (IOLs) to enhance the quality and contrast of the image, multifocal and enhanced-depth-of-focus IOLs to correct presbyopia, advancements in biometry and IOL power calculation, prevention of secondary capsule opacification by improvements in the design and material of the IOLs and surgical techniques like capsule polishing and posterior capsulorhexis, and pharmacological prophylaxis and possible future treatment of the cataract itself. Finally, cost-effectiveness and future potential of same-session bilateral cataract surgery are discussed. PMID:26982642

    Wang, Jenny; Sramek, Christopher; Paulus, Yannis M.; Lavinsky, Daniel; Schuele, Georg; Anderson, Dan; Dewey, David; Palanker, Daniel V.

    2013-03-01

    Application of femtosecond lasers to cataract surgery has added unprecedented precision and reproducibility but ocular safety limits for the procedure are not well-quantified. We present an analysis of safety during laser cataract surgery considering scanned patterns, reduced blood perfusion, and light scattering on residual bubbles formed during laser cutting. Experimental results for continuous-wave 1030 nm irradiation of the retina in rabbits are used to calibrate damage threshold temperatures and perfusion rate for our computational model of ocular heating. Using conservative estimates for each safety factor, we compute the limits of the laser settings for cataract surgery that optimize procedure speed within the limits of retinal safety.

  8. SMALL INCISION CATARACT SURGERY VERSUS PHACOEMULSIFICATION FOR IMMATURE CATARACT: A SINGLE BLIND RANDOMIZED CONTROLLED TRIAL

    Md. Jawed

    2014-08-01

    Full Text Available BACKGROUND: Manual small incision cataract surgery (SICS has given visual results almost equivalent to Phacoemulsification but limited studies are available regarding the efficacy of small incision cataract surgery in phaco suitable immature cataracts. OBJECTIVE: To compare manual small incision cataract surgery and Phacoemulsification in immature cataracts. MATERIALS AND METHODS: A single blind randomized controlled trial was conducted with 105 eyes each for small incision cataract surgery and Phacoemulsification. RESULT: Mean IOL power was similar in both Phacoemulsifications as well as SICS. Four cases of posterior capsular rupture occurred in Phacoemulsification while one case of zonular dialysis occurred in SICS. Uncorrected visual acuity was good (6/6-6/18 in 80.0 % of the phaco and 93.33 % of the SICS group. CONCLUSION: SICS surgical technique resulted in significantly better visual acuity on the 1st postoperative day in comparison with phaco. Hence, SICS with rigid PMMA IOL implantation being a cheaper, faster and easier technique, may be recommended for immature cataract surgery in the developing countries

  14. Cataract surgery in a case of carotid cavernous fistula

    Akshay Gopinathan Nair

    2014-01-01

    Full Text Available A carotid-cavernous fistula (CCF is an abnormal communication between the cavernous sinus and the carotid arterial system. The ocular manifestations include conjunctival chemosis, proptosis, globe displacement, raised intraocular pressure and optic neuropathy. Although management of CCF in these patients is necessary, the ophthalmologist may also have to treat other ocular morbidities such as cataract. Cataract surgery in patients with CCF may be associated with many possible complications, including suprachoroidal hemorrhage. We describe cataract extraction surgery in 60-year-old female with bilateral spontaneous low-flow CCF. She underwent phacoemulsification via a clear corneal route under topical anesthesia and had an uneventful postoperative phase and recovered successfully. Given the various possible ocular changes in CCF, one must proceed with an intraocular surgery with caution. In this communication, we wish to describe the surgical precautions and the possible pitfalls in cataract surgery in patients with CCF.

  2. Role of cataract surgery in lowering intraocular pressure

    To study the effects of cataract surgery in lowering of intraocular pressure (IOP). Study Design: Retrospective study. Place and Duration of Study: The Department of Ophthalmology, Combined Military Hospital, Rawalpindi from January 2011 to December 2013. Patients and Methods: The study included a total of 250 patients; of which 100 cases had simple cataract with no coexisting disease, 100 cases had cataract with primary open angle glaucoma and 50 cases of cataract had accompanying pseudoexfoliation glaucoma. All patients were assessed and recorded preoperatively for their IOP, vision, depth of anterior chamber (ACD), angle of anterior chamber by gonioscopy and glaucoma medications being used. Cataract surgery was performed by phacoemulsification and IOL implantations in all cases. These patients were followed up for a period of six months. Results: The intraocular ressure of all these patients was recorded at monthly interval for six months. The IOP showed a significant decrease in all cases and remained constant till the end of the study. A marked improvement of vision was noted in all cases. The depth of the anterior chamber increased and the angle also widened in all cases. Discussion: Cataract surgery has been found to reduce IOP along with improvement in vision.

    2016-03-01

    Full Text Available INTRODUCTION Phacoemulsification is the method of choice in most of the western nations and tertiary care ophthalmology centres in India, while manual small incision cataract surgery (MSICS is the surgical technique preferred by most of the ophthalmic surgeons working in smaller centres. Many studies have indicated that the MSICS technique is preferable for smaller centres, especially in developing countries, as the duration of surgery and requirement of equipment tends to be much smaller. This study was aimed at comparing the outcomes of MSICS and phacoemulsification surgeries carried out over a period of three months at a tertiary care hospital in South India. MATERIALS AND METHODS Patients diagnosed to have age related cataract and undergoing surgery in this institution were included in the study. The choice of surgical intervention was based on the preference of the operating surgeon and choice of the patient. The patients were followed up at the end of one week on their review visit to the outpatient department of the hospital. The incidence of postoperative complications was enquired, apart from measurement of visual acuity and corneal diameters. RESULTS A total of 106 participants were included in the study. Eighty percent of the patients who underwent phacoemulsification had some improvement in vision, while 81.9% of the participants in the MSICS group showed improvement, (p-0.825, only one participant had a complication related to the surgery, and he belonged to the MSICS group. The changes in K1 (p-0.547 and K2 (p-0.698 corneal diameters during surgery was also not significantly different between the groups. CONCLUSIONS It was observed that MSICS and phacoemulsification procedures have similar outcomes when used at a tertiary care teaching hospital in South India. A large multicentric Randomised Control Trial (RCT is warranted to compare the outcomes of the two surgical procedures and the cost-effectiveness of each, before concrete

    Introduction. Cataracts cause about 50% of world blindness. There is little likelihood of effective prevention becoming available in the next few years and so the only treatment will remain surgical. For many of the other major causes of world blindness, like trachoma, xerophthalmia and onchocerciasis, the remedy is community-based, not hospital-based, and requires prevention rather than treatment. The prevalence of blinding cataract will only increase as people live longer, so cataract will ...

    Full Text Available Background: The aim of this study was to evaluate the indications, safety, benefits, disadvantagesand advantages, and the visual outcomes for simultaneous bilateralcataract surgery (SBCS under general anesthesia.Methods: This retrospective case review pertained to a period spanning from June1998 through June 2005 inclusively, and comprised of 27 consecutivepatients (54 eyes that underwent simultaneous bilateral cataract surgeryunder general anesthesia at the Kaohsiung Chang Gung Memorial Hospital,Taiwan. Surgery modalities included phacoemulsification, extracapsularcataract extraction, lens aspiration and intraocular lens implantation.Outcome measures included postoperative best correct visual acuity (BCVAas well as intraoperative and postoperative complication rates. Due to thebipolas distribution of the age, we arbitrarily divided our cases into youngergroup (Group Y, younger than 20 years old and older group (Group O, equalto or older than 20 years old.Results: Thirty-eight of the 54 eyes (60% in the younger group and 76.5% in theolder group, featuring measured preoperative and postoperative BSCVA,achieved improved visual acuity following SBCS. Two eyes (5.9% in theolder group demonstrated poorer visual acuity postoperatively than preoperatively.Seven patients (40% in the younger group and 17.6% in the oldergroup were not able to express VA due to their particular medical conditionssuch as mental disease and young age. Intraoperative and postoperative complicationrates were similar to those cited in previous reports of analogousbut unilateral extracapsular surgery and simultaneous bilateral cataractsurgery. Endophthalmitis did not arise in any of the eyes operated upon andreported on herein, and no examples of bilateral complications that resultedin visual loss occurred in our patients.Conclusion: SBCS could be a good choice when cataract surgery needs to be performedunder general anesthesia.

    2014-11-01

    Full Text Available INTRODUCTION: Cataract is the leading cause of preventable blindness in India. Manual Small Incision Cataract Surgery is still the preferred method of cataract surgery because of its low cost and non-dependence on costly equipments. Postoperatively astigmatism is an important cause of poor uncorrected visual acuity after cataract surgery. Purpose: The purpose of this study was to assess corneal astigmatism in manual small incision cataract surgery in superior versus temporal incision. MATERIALS AND METHODS: A total of 100 patients were included in our study. 50 patients received superior incision and 50 patients received temporal incision. Surgically induced astigmatism was calculated in these patients postoperatively. RESULTS: We observed mean 1.16 D of surgically induced astigmatism in patients with superior incision and mean 0.62 D of astigmatism in patients with temporal incision at the end of 12th postoperative week. CONCLUSION: The results of the present study showed a favourable influence of temporal incision over superior incision in manual incision cataract surgery in terms of surgically induced astigmatism.

    Full Text Available A randomized single blinded clinical trial to compare the cost-effectiveness of cataract surgery between extracapsular cataract extraction (ECCE and phacoemulsification (PEA was conducted at Hospital Universiti Kebangsaan Malaysia (HUKM from March 2000 until August 2001. The cost of a cataract surgery incurred by hospital, patients and households were calculated preoperatively, one week, two months (for both techniques and six months (for ECCE only. Effectiveness of cataract surgery was assessed using Visual Function 14 (VF-14, quality of life measurement specifically for vision. The cost analysis results from each 50 subjects of ECCE and PEA group showed that average cost for one ECCE after six months post-operation is USD 458 (± USD 72 and for PEA is USD 528 (± USD 125. VF-14 score showed a significant increased after a week, two months and six months post-operation compared to the score before operation for both techniques (p<0.001. However, there was no significant difference between them (p = 0.225. This study indicated that ECCE is more cost effective compared to PEA with cost per one unit increment of VF-14 score of USD 14 compared to USD 20 for PEA.

    2013-04-01

    Full Text Available INTRODUCTION: Patient dissatisfaction is very common even with go od cataract surgery. Cataract surgery done by phacoemulsification with f oldable IOL implantation results in minimal astigmatism. This results in early rehabilitation t hereby rendering the patient nearly emmetropic for both distant and near work. But the drawbacks of this surgical technique are high cost, steep learning curve and is entirely mach ine dependent. This study has been conducted to know if it is possi ble to achieve minimal astigmatism with MSICS with rigid PMMA IOL in selected cases th us achieving cost effectiveness and reducing the duration of surgery.

    2006-01-01

    During the past decade, advances in techniques and technology led to major changes in cataract surgical practice patterns. In this progression towards ever faster eye rehabilitation after surgery, simultaneous bilateral cataract surgery (SBCS) may be the next and ultimate step. It is not routinely performed: however, there are certain situations in which SBCS might be beneficial to the patients. It has been considered a good option in patients who have significant cataract in both eyes and are not good candidates for having anesthesia and surgery twice. The question is, if the benefits by bilateral surgery justify the risk of simultaneous complications, in particular endophthalmitis. In this perspective we present the clinical, social and economic advantages and disadvantages of such surgical procedures. PMID:17290841

    2012-01-01

    Full Text Available Background/Aim. Cataract surgery has become one of the safest procedures in medicine thanks to advances in technology and surgical techniques. Although minimal, we still witness different complications. The aim of this study was to compare visual outcome and complication rate in different techniques of cataract surgery, ie in cataract surgeries with various corneal incision width. Methods. The study included 3,457 consecutive patients, ie 4,670 eyes that had undergone cataract surgery. The used surgical techniques were: extracapsular cataract extraction, phacoemulsification/ forceps IOL implantation, phacoemulsification/ injector IOL implantation, microincision cataract surgery (MICS. Patient follow up was 6 months. Patients were evaluated for: visual aquity, corneal astigmatism, cellular reaction in the anterior chamber, IOL position. Results. Uncorrected visual aquity 30 days postoperatively was ≥ 0.5 in 30% of the eyes - ECCE; 54.7% of the eyes - phacoemulsification/forceps IOL implantation; 63.0% of the eyes - phacoemulsification/injector IOL implantation; 5/8 of the eyes - MICS. Endophthalmitis was detected in 0.15% of the eyes - ECCE and 0.1% of the eyes - phacoemulsification/forceps IOL implantation. In eyes with phacoemulsification/injector IOL implantation or microincision cataract surgery (MICS there were no cases of endophthalmitis. After a 6-month period intraocular lens were dislocated in 7.2% of the eyes - ECCE, and 0.6% of the eyes - phacoemulsification/PMMA IOL. There was no IOL dislocation in other surgical techniques. Conclusion. Shorter corneal incision implies less complications, less operative trauma, faster visual rehabilitation and better visual outcome.

    Crystalline lens dislocation and zonular dialysis during intraocular surgery are recognised features of the pseudoexfoliation syndrome (PES). A case is reported in which zonular dialysis occurred in both eyes during extracapsular cataract extraction. In particular surgery was complicated by difficulty in performing anterior capsulotomy. Careful preoperative assessment and peroperative technique may help to reduce the risk of surgical complication in PES.

There is little likelihood of effective prevention becoming available in the next few years and so the only treatment will remain surgical. For many of the other major causes of world blindness, like trachoma, xerophthalmia and onchocerciasis, the remedy is community-based, not hospital-based, and requires prevention rather than treatment. The prevalence of blinding cataract will only increase as people live longer, so cataract will continue to be, by far, the most important treatable cause of blindness.

  5. Laser-assisted cataract surgery and other emerging technologies for cataract removal

    1999-01-01

    Full Text Available As we near the end of this century, refractive cataract surgery has become a reality through concerted contributions from ultrasonic phacoemulsification, foldable intraocular lens (IOL implantation technology and keratorefractive surgery. As we enter the new millennium, our sights are set on realizing another dream: accommodative IOL surgery. Towards achieving this goal, many advances have been made in both techniques and technology of cataract removal. Lasers in particular have been under investigation for cataract removal for nearly two decades. The technology has now reached a stage where cataract can indeed be removed entirely with laser alone. Neodymium:YAG and erbium:YAG are the laser sources currently utilized by manufacturers of laser phaco systems. Initial clinical experience reported in the literature has served to highlight the capabilities of lasers and the need for further refinement. Despite the excitement associated with the availability of this alluring new technology for cataract removal, it is necessary to develop more effective laser systems and innovative surgical techniques that optimize its capabilities if laser phaco surgery is to be a genuine improvement over current techniques.

    1995-01-01

    Full Text Available Surgery for cataract blindness, a major health problem, is undergoing a rapid transition. This study characterizes cataract surgery in India in terms of practice setting and surgical procedure. A survey questionnaire was mailed in December 1992 to 4356 members of the All India Ophthalmological Society, resident in India, requesting data on cataract surgery cases within the past 12 months. Two thousand one hundred thirty-four (49% ophthalmologists responded to the survey. Of the 1,023,070 cataract cases reported, two-thirds were private patients. Among private patients, 26.0% received extracapsular cataract extraction (ECCE with intraocular lens (IOL implantation and 20.7% received ECCE without an IOL. Among patients operated under government auspices, 9.1% received ECCE with IOL and 22.4% received ECCE without IOL. Overall, 82.8% of active surgeons reported experience with the ECCE procedure. The cataract case load in the private sector and the frequency of ECCE, with or without IOL implantation, among both private and government-operated cases is greater than previously recognized.

  8. [Incisions for biaxial and coaxial microincision cataract surgery].

    Müller, M; Kohnen, T

    2010-02-01

    Microincision cataract surgery (MICS) represents a new level in the development of cataract surgery. Phacoemulsification with intraocular lens (IOL) implantation via incisions of biaxial approach, with separation of the phaco tip and irrigation (B-MICS). Compared with standard small-incision cataract surgery, the advantages of MICS are less corneal astigmatism and fewer corneal surface irregularities, with favorable implications for visual quality and early rehabilitation. In the effort toward smaller incisions, special interest should be given to wound integrity, especially regarding the risk of endophthalmitis. With limited corneal elastic capacity, irreversible expansion of the incision with tissue laceration may occur. Smaller incisions are superior only if they cause less trauma. This requires an optimized relationship between incision size and manipulation during IOL implantation as well as attention to safety issues. MICS offers a platform for new benchmarks in phacoemulsification. PMID:20107810

  10. Sutureless Non-phaco Cataract Surgery: A Solution to Reduce Worldwide Cataract Blindness?

    Albrecht Hennig

    2003-01-01

    Full Text Available The Search for Appropriate Sutureless Cataract Surgery. During the last decade, in industrialised countries phacoemulsification has largely replaced ab-externo extracapsular cataract extraction with posterior chamber intraocular lenses (ECCE/PC IOL with sutures. The small self-sealing phaco incision provides rapid visual rehabilitation, and the surgery is increasingly done on an outpatient basis. However, in developing countries phacoemulsification is performed only on selected patients, usually those able to pay high treatment charges. The reasons for this include the cost of a phaco machine and consumables such as foldable IOLs. Until now, phacoemulsification has played a very limited role in the reduction of cataract blindness in low income countries. Therefore, eye surgeons in developing countries are searching for alternatives to phacoemulsification. We need a surgical technique which is easy to learn, provides an immediate good uncorrected visual outcome, and is affordable to most cataract patients. Such a technique would advance cataract surgery in low income countries and contribute to reaching the goal of VISION 2020: The Right to Sight.

  16. Vitrectorhexis versus forceps posterior capsulorhexis in pediatric cataract surgery

    Lav Kochgaway

    2013-01-01

    Full Text Available This study was done to compare the results of posterior continuous curvilinear capsulorhexis created using forceps with those created using vitrector in eyes suffering from congenital cataract. Vitrectorhexis term was first used by Wilson et al in 1999. [1] Fifty eyes with congenital and developmental cataract were included in this study. The posterior capsulorhexis was created using utrata forceps in 17 eyes or through a vitrector in 33 eyes. Forceps capsulorhexis was performed before IOL implantation, while vitrectorhexis was performed after IOL implantation in the bag. The results of both the surgery were compared using the following criteria: incidence of extension of rhexis, ability to achieve posterior rhexis of appropriate size, ability to implant the IOL in the bag, the surgical time, and learning curve. Vitrectorhexis after IOL implantation was an easy to learn alternative to manual posterior continuous curvilinear capsulorhexis in pediatric cataract surgery. It was more predictable and reproducible, with a short learning curve and lesser surgical time.

Mean postoperative spherical equivalent refractive error was -2.13±3.02 D, which significantly differed from the target refraction (-0.73±0.29 D, P=0.004. At final follow-up, 89.5% of the corneal grafts remained clear. Conclusion: The triple procedure is a safe and effective approach to restore vision in patients with coexisting corneal pathologies and cataracts. However, unacceptable postoperative refractive error can be anticipated.

    Full Text Available Background: Cataract is the leading cause of blindness in the world. Its only effective treatment is surgery, with a high rate of efficiency, but it is not always practiced due to several reasons that limit access to health services.Objective: To identify clinical and epidemiological behaviour of patients after cataract surgery. Methods: An observational, descriptive and cross-sectional study conducted in the "José Joaquín Palma" Ophthalmology Center in the town of San Cristóbal, Guatemala. We included all patients over 18 years old meeting the inclusion criteria who had had a cataract surgery between July and December 2007. The following variables were analyzed: age, sex, skin color, place of origin, ocular and systemic personal medical history, etiologic type of cataract and intra and immediate postoperative complications. Results: 63.3% of the patients are in the 60 years on age group, with a slight predominance of females (51.89% and most of them come from the rural areas (66.66%. Among personal medical histories myopia was detected (14.17% and among systemic medical histories there were arterial hypertension (25.98% and diabetes mellitus (22.04%. Senile cataract was more frequent (52.75%. The most frequent intraoperative complications were posterior capsule ruptures with or without vitreous loss (29.548% and 3.37% respectively and corneal edema in the immediate postoperative (5.48%. Conclusions: The results of clinical and epidemiological characterization of patients after cataract surgery included in this series do not differ from those of similar studies, except for the personal glaucoma history.

    1996-01-01

    Presented is an assessment of the cost-effectiveness of cataract surgery using cost and services data from the Lumbini Zonal Eye Care Programme in Nepal. The analysis suggests that cataract surgery may be even more cost-effective than previously reported. Under a "best estimate" scenario, cataract surgery had a cost of US$5.06 per disability-adjusted life year (DALY). This places it among the most cost-effective of public health interventions. Sensitivity analysis indicates that cataract surg...

    Conclusion: The recent trend of intentional overcorrection in one eye following modern cataract surgery in order to provide some functional near vision indicates that benchmark for success in getting “good visual outcomes” postoperatively (vision of ≥6/18 may need to be revised.

  5. A Comparison of Different Operating Systems for Femtosecond Lasers in Cataract Surgery.

    Wu, B M; Williams, G P; Tan, A; Mehta, J S

    2015-01-01

    The introduction of femtosecond lasers is potentially a major shift in the way we approach cataract surgery. The development of increasingly sophisticated intraocular lenses (IOLs), coupled with heightened patient expectation of high quality postsurgical visual outcomes, has generated the need for a more precise, highly reproducible and standardized method to carry out cataract operations. As femtosecond laser-assisted cataract surgery (FLACS) becomes more commonplace in surgical centers, further evaluation of the potential risks and benefits needs to be established, particularly in the medium/long term effects. Healthcare administrators will also have to weigh and balance out the financial costs of these lasers relative to the advantages they put forth. In this review, we provide an operational overview of three of five femtosecond laser platforms that are currently commercially available: the Catalys (USA), the Victus (USA), and the LDV Z8 (Switzerland).

  8. Instruments for cataract surgery: results from our survey

    Daksha Patel; Phil Hoare

    2011-01-01

    For any operation, including cataract surgery, the appropriate instruments must be available and in good working order. If instruments are not available, or are blunt, or do not function properly, it may be necessary to delay or postpone surgery. Using such instruments in an operation can result in a poor outcome, or even pose a risk to surgeons and their assistants.The impact is therefore considerable, and can damage the reputation of the hospital in the community.

  9. Conjunctival inclusion cysts following small incision cataract surgery

    Narayanappa Shylaja

    2010-01-01

    Full Text Available The occurrence of acquired conjunctival inclusion cysts following various ophthalmic surgeries such as strabismus surgery, scleral buckling, pars plana vitrectomy, ptosis surgery and phacoemulsification has been reported. We report two cases of conjunctival inclusion cysts following manual Small Incision Cataract Surgery (SICS in two male patients aged 65 and 67 years. The cysts originated from the scleral tunnel used for manual SICS. Both were treated by excision and confirmed histopathologically. No recurrence was noted at three months follow-up. To our knowledge, conjunctival inclusion cysts following SICS have not been reported previously. Careful reflection of conjunctiva during tunnel construction and posterior chamber intraocular lens implantation may prevent their occurrence.

  12. Maximal mydriasis evaluation in cataract surgery

    Ho Tony

    1992-01-01

    Full Text Available We propose the Maximal Mydriasis Test (MMT as a simple and safe means to provide the cataract surgeon with objective and dependable pre-operative information on the idiosyncratic mydriatic response of the pupil. The MMT results of a consecutive series of 165 eyes from 100 adults referred for cataract evaluation are presented to illustrate its practical applications and value. The results of the MMT allows the surgeon to anticipate problem eyes pre-operatively so that he can plan his surgical strategy more appropriately and effectively. Conversely, the surgeon can also appropriately and confidently plan surgical procedures where wide pupillary dilation is important. The MMT has also helped improve our cost-effectiveness by cutting down unnecessary delays in the operating room and enabling better utilisation of restricted costly resources.

  13. Focussing both eyes on health outcomes: revisiting cataract surgery

    Davis Jennifer C

    2012-09-01

    Full Text Available Abstract Background The appropriateness of cataract surgery procedures has been questioned, the suggestion being that the surgery is sometimes undertaken too early in the disease progression. Our three study questions were: What is the level of visual impairment in patients scheduled for cataract surgery? What is the improvement following surgery? Given the thresholds for a minimal detectable change (MDC and a minimal clinically important difference (MCID, do gains in visual function reach the MDC and MCID thresholds? Methods The sample included a prospective cohort of cataract surgery patients from four Fraser Health Authority ophthalmologists. Visual function (VF-14 was assessed pre-operatively and at seven weeks post-operatively. Two groups from this cohort were included in this analysis: ‘all first eyes’ (cataract extraction on first eye and ‘both eyes’ (cataract removed from both eyes. Descriptive statistics, change scores for VF-14 for each eye group and proportion of patients who reach the MDC and MCID are reported. Results One hundred and forty-two patients are included in the ‘all first eyes’ analyses and 55 in the ‘both eyes’ analyses. The mean pre-operative VF-14 score for the ‘all first eyes’ group was 86.7 (on a 0–100 scale where 100 is full visual function. The mean change in VF-14 for the 'both eyes' group was 7.5. Twenty-three percent of patients achieved improvements in visual function beyond the MCID threshold and 35% saw improvement beyond the MDC. Conclusions Neither threshold level for MDC or MCID for the VF-14 scale was achieved for a majority of patients. A plausible explanation for this is the very high levels of pre-operative visual functioning.

    1992-01-01

    Eighteen eyes in 17 patients with Fuchs' heterochromic iridocyclitis underwent cataract extraction with or without intraocular lens implantation (17 extracapsular and one intracapsular). Intraoperative complications included hyphaema, poor pupillary dilatations, and localised zonule dehiscence with vitreous loss. Only four eyes developed a marked anterior uveitus (two pseudophakic and two aphakic) which resolved within 2 weeks with topical steroids. Three eyes developed a rise in intraocular ...

    <正>INTRODUCTION Femtosecond laser technology,introduced clinically for ophthalmic surgery as a technique for creating lamellar flaps in laser in situ keratomileusis(LASIK),has recently been developed into a tool for cataract surgery.Preliminary experience for femtosecond laser-assisted cataract surgery show appropriate safety and efficacy,and possible advantage over conventional cataract surgery[1-4].The ability of the femtosecond laser to fragment the lens results in the need for less ultrasound energy to be expended inside the eye.Several studies indicate that less effective phacoemulsification time is needed to emulsify the lens

  16. Prevalence of myopic shifts among patients seeking cataract surgery

    Rafael Iribarren

    2013-06-01

    Full Text Available Modern cataract surgery by phacoemulsification is a widely accepted procedure with a rapid recovery time. The prescription of specific intraocular lens, implanted during surgery, makes it possible to anticipate whether the patient will need reading glasses after the procedure. The present study analyses a sample of cataract surgery patients to show the frequency of myopic shifts related to nuclear opacity, which can result in clear near vision before surgery. A non-selected sample of consecutive patients who underwent elective cataract surgery in a private clinic was studied retrospectively. The myopic shift in refraction was assessed by comparing the old prescription with the spectacle correction at the time of interviewing.The mean age of the 229 subjects studied was 71.5 ± 10.4 years (109, 47.6%, males. A myopic shift in refraction, defined as at least - 0.5 diopters, was present in 37.1% of subjects (95% CI: 30.8%-43.4%. The mean change in refraction in these subjects was -2.52 ± 1.52 diopters. The percentage of subjects who had developed a myopic shift was significantly greater in those who presented greater nuclear opalescence. There were also differences in the mean myopic shift by refractive group, with the emmetropes having the greatest myopic shift. In this study of patients seeking cataract surgery in a clinical setting, more than one third had myopic shifts in refraction. This must be taken into account in order that patients maintain the benefit of clear near vision after surgery.

    2014-04-01

    Full Text Available The purpose of this study is to show how a public eye care center in Turkey initiated Six Sigma principles to reduce the number of complications encountered during and after phacoemulsification cataract surgeries. To analyze the 3-year data, main tools of Six Sigma’s Define-Measure-Analyze-Improve-Control (DMAIC improvement cycle such as SIPOC table, Fishbone Diagram and, Failure, Mode and Effect Analysis were implemented. Experience of the ophthalmic surgeon, patient’s anatomy, cooperation of patient during the surgery, sterilization and hygiene, attention of assistant surgeon, calibration of equipment and quality/chemical composition of intraocular material were identified to be Critical-to-Quality (CTQ factors for a successful phacoemulsification cataract surgery. The most frequently occurring complication was found to be iris atrophy. The process sigma level for the process was found to be 3.958.

The mean age of patients was 91.2 ± 2.3 years (range 90–100 years old. Phacoemulsification (phaco was done on 113 of 122 eyes, and 9 of 122 eyes had extracapsular cataract extraction (ECCE. Postoperative visual acuity and intraocular pressure (IOP were analyzed on the first postoperative day, 3 months after surgery, and 6 months after surgery.Results: Best corrected visual acuity (BCVA improved in 100 of 122 eyes (82.0%. BCVA remained the same in 20 of 122 eyes (16.4% and decreased in 2 of 122 eyes (1.6%, mainly because of coexisting age-related macular degeneration (AMD. The BCVA 3 months after surgery was ≥0.8 in 23 of 122 eyes (18.9%, between 0.5 and 0.7 in 28 of 122 eyes (22.3%, and between 0.2 and 0.4 in 33 of 122 eyes (27.1%. We found significant implications of cataract surgery on decreasing IOP in the studied group of patients suffering from glaucoma compared to the patients without glaucoma.Conclusion: Advanced age is not a contraindication for cataract surgery. The results of the study showed that when systemic conditions are stable, both phaco and ECCE with

    Full Text Available The aim of study was to achieve complete cortical cleanup and avoid problems related with sideport during Small Incision Cataract Surgery (SICS so as to have a good visual out come with minimal recovery period, and a better quality of life. After nucleus delivery, cortical cleanup is an important step in any cataract surgical procedure. Cortex especially subincisional area (11 to 1 o’clock is difficult to manage intraoperatively. Bimanual irrigation aspiration through two side ports, aspiration by J cannula, iris massage manoeuver, ice cream scoop manoeuver are various techniques of cortical matter aspiration. We acquired the technique of aspiration of subincisional cortex without using side port in all cases by paying attention on type of cataract, status of pupil, use of Adrenalin mixed BSS intraoperatively, Tunnel construction, Capsulorhexis size and capsular rim size at 12 o’clock. MATERIAL AND METHODS In this retrospective study of 1 year from 2013 to 2014, 60 patients (60 eyes aged 40 years or older attending the General Ophthalmic Department were included in the study group with another group of 60 patients (60 eyes as controls.

    2012-09-01

    Femtosecond lasers have added unprecedented precision and reproducibility to cataract surgery. However, retinal safety limits for the near-infrared lasers employed in surgery are not well quantified. We determined retinal injury thresholds for scanning patterns while considering the effects of reduced blood perfusion from rising intraocular pressure and retinal protection from light scattering on bubbles and tissue fragments produced by laser cutting. We measured retinal damage thresholds of a stationary, 1030-nm, continuous-wave laser with 2.6-mm retinal spot size for 10- and 100-s exposures in rabbits to be 1.35 W (1.26 to 1.42) and 0.78 W (0.73 to 0.83), respectively, and 1.08 W (0.96 to 1.11) and 0.36 W (0.33 to 0.41) when retinal perfusion is blocked. These thresholds were input into a computational model of ocular heating to calculate damage threshold temperatures. By requiring the tissue temperature to remain below the damage threshold temperatures determined in stationary beam experiments, one can calculate conservative damage thresholds for cataract surgery patterns. Light scattering on microbubbles and tissue fragments decreased the transmitted power by 88% within a 12 deg angle, adding a significant margin for retinal safety. These results can be used for assessment of the maximum permissible exposure during laser cataract surgery under various assumptions of blood perfusion, treatment duration, and scanning patterns.

    2014-08-01

    The purpose of this study is to measure the impact of tamsulosin intake on five postoperative cataract surgery complications (toxic anterior segment syndrome, rebound uveitis, retinal detachment, macular edema, and postoperative endophthalmitis). This retrospective cohort study was conducted at University Hospital of Henares. The study included 660-eyes of 660 patients submitted to cataract surgery at the ophthalmology unit of Hospital del Henares (Madrid) between 2 March 2009 and 28 February 2010. Extracapsular cataract extraction, combined glaucoma and cataract surgery phacovitrectomy, posterior capsule rupture and zonular damage were considered exclusion criteria. Clinical charts were reviewed during July 2012. Patients were divided in two groups (exposed and non-exposed to tamsulosin). Cumulative incidence of toxic anterior segment syndrome, rebound uveitis, retinal detachment, macular edema and postoperative endophthalmitis were compared in both groups. Rebound uveitis (relative risk [RR] 3.39; confidence interval [CI] 1.63-7.08) and macular edema (RR 4.15; CI 1.06-16.22) were more common in the tamsulosin-exposed group. Retinal detachment had a similar incidence in both groups. We observed no cases of endophthalmitis or toxic anterior segment syndrome in either of the two groups. Tamsulosin exposure in this cohort was associated with a higher risk of rebound uveitis and macular edema but the other three studied postoperative complications had a similar incidence in both groups.

    Ravindra M

    2009-01-01

    Nucleus management is critical in manual small incision cataract surgery (MSICS), as the integrity of the tunnel, endothelium and posterior capsule needs to be respected. Several techniques of nucleus management are in vogue, depending upon the specific technique of MSICS. Nucleus can be removed in toto or bisected or trisected into smaller segments. The pressure in the eye can be maintained at the desired level with the use of an anterior chamber maintainer or kept at atmospheric levels. In ...

    2013-01-01

    Full Text Available Purpose: To evaluate the effect of cataract surgery on intraocular pressure (IOP in filtered eyes with primary angle closure glaucoma (PACG. Methods: In this prospective interventional case series, 37 previously filtered eyes from 37 PACG patients with mean age of 62.1±10.4 years were consecutively enrolled. All patients had visually significant cataracts and phacoemulsification was performed at least 12 months after trabeculectomy. Visual acuity, IOP and the number of glaucoma medications were recorded preoperatively, and 1, 3, 6 and 12 months after surgery. Anterior chamber (AC depth was measured preoperatively and 3 months after cataract surgery with A-scan ultrasonography. The main outcome measure was IOP at 12 months. Results: IOP was decreased significantly from 18.16±5.91 mmHg at baseline to 15.37±2.90 mmHg at final follow-up (P<0.01. The mean number of glaucoma medications was significantly decreased from 1.81±0.24 to 0.86±1.00 (P=0.001 at 1 year postoperatively. At final follow up, 36 (97.2% eyes and 32 (86.4% eyes had IOP≤21 and IOP≤18 mmHg, respectively; 14 (37.8% eyes and 9 (24.3% eyes had IOP≤21 and IOP≤18 mmHg without medications, respectively. The magnitude of IOP reduction was correlated with higher preoperative IOP (r=0.85, P<0.001, shallower preoperative AC depth (r=-0.38, P=0.01 and greater changes in AC depth (r=-0.39, P=0.01. Conclusion: Cataract surgery reduces IOP and the number of glaucoma medications in previously filtered PACG eyes. This reduction seems to be greater in patients with higher preoperative IOP and shallower anterior chambers.

    Full Text Available Background: The twenty-first century is characterized by a progressive aging in the population, with the subsequent demand of medical care it implies due to the polimorbility rates typical of this stage of life. Objective: to prove the positive influence of cataract surgery in biopsychosocial adaptation of elderlies. Methods: a descriptive study conducted from January to June 2008 in the General University Hospital "Dr. Aldereguía Gustavo Lima’’ in Cienfuegos. The 60 elder patients who underwent surgery cataract in that period were included. Geriatric evaluation was used as assessment instrument. It was applied before and 3 months after cataract surgery and included the Yesavage Geriatric Depression Rating Scale to measure emotional function and the Katz index for functional evaluation. The variables used are part of the preoperative geriatric assessment. Among them we can find biomedical, social, functional and psychological aspects as well as-risk benefit and anesthetic risks analysis. Results: the largest amount of patients was between 70 and 74 years old, predominantly males and white skinned. Most frequent personal pathological records were arthropathies, diabetes mellitus and hypertension. A significant relationship between initial visual acuity levels and depression rates was found; as well as limitations in performing basic daily life activities. Conclusions: with surgical intervention an improved visual acuity was achieved and a number of functional capacities were reestablished to allow a better biopsychosocial adaptation in elderlies.

  14. Bilateral photic maculopathy after extracapsular cataract surgery: a case report

    Chalfin, Steven

    1997-05-01

    A 42 year old Caucasian female underwent uncomplicated extracapsular cataract extraction with posterior chamber lens implantation in the left eye, using a Zeiss model OpMi-6 operating microscope. Her postoperative course was unremarkable and she achieved a corrected visual acuity of 20/15+3. A lesion consistent with a photoretinal injury was noted inferior to the fovea. Seven months later the patient underwent cataract extraction in the right eye. Special care was taken to minimize light exposure during the procedure, including reducing the microscope illumination, minimizing operating time, intraoperative pharmacologic miosis, and using a corneal light shield. Despite these precautions, the patient developed a photoretinal injury almost identical to that in the contralateral eye. Postoperative corrected visual acuity was 20/15+3. Recent studies have reported incidences of retinal photic injuries from operating microscopes between 0 and 28 percent of patients. Several risk factors have been identified, including light intensity, intensity of the blue light component, and exposure time. The occurrence of a retinal photic injury in this patient despite precautions, development of bilateral cataracts at a young age, and a strong family history of early cataracts may indicate an inherited susceptibility to light induced damage. The American National Standards Institute is developing a product performance standard which will be applicable to operating microscopes used in ophthalmic surgery. The as yet undetermined role of individual susceptibility to retinal photic injury should be considered in the formulation of this standard.

  2. Iris recognition as a biometric method after cataract surgery

    Roizenblatt Jaime

    2004-01-01

    Full Text Available Abstract Background Biometric methods are security technologies, which use human characteristics for personal identification. Iris recognition systems use iris textures as unique identifiers. This paper presents an analysis of the verification of iris identities after intra-ocular procedures, when individuals were enrolled before the surgery. Methods Fifty-five eyes from fifty-five patients had their irises enrolled before a cataract surgery was performed. They had their irises verified three times before and three times after the procedure, and the Hamming (mathematical distance of each identification trial was determined, in a controlled ideal biometric environment. The mathematical difference between the iris code before and after the surgery was also compared to a subjective evaluation of the iris anatomy alteration by an experienced surgeon. Results A correlation between visible subjective iris texture alteration and mathematical difference was verified. We found only six cases in which the eye was no more recognizable, but these eyes were later reenrolled. The main anatomical changes that were found in the new impostor eyes are described. Conclusions Cataract surgeries change iris textures in such a way that iris recognition systems, which perform mathematical comparisons of textural biometric features, are able to detect these changes and sometimes even discard a pre-enrolled iris considering it an impostor. In our study, re-enrollment proved to be a feasible procedure.

  3. Femtosecond laser-assisted cataract surgery-current status and future directions.

    Grewal, Dilraj S; Schultz, Tim; Basti, Surendra; Dick, H Burkhard

    2016-01-01

    Femtosecond laser-assisted cataract surgery (FLACS) putatively offers several advantages over conventional phacoemulsification. We review the current status of FLACS and discuss the evolution of femtosecond lasers in cataract surgery and the currently available femtosecond laser platforms. We summarize the outcomes of FLACS for corneal wound creation, limbal relaxing incisions, capsulotomy, and lens fragmentation. We discuss surgical planning, preoperative considerations, clinical experiences including the learning curve and postoperative outcomes with FLACS, and also the cost effectiveness of FLACS. We present the intraoperative complications and management of challenging cases where FLACS offers an advantage and also speculate on the future directions with FLACS. Further advancements in laser technology to refine its efficacy, advancement in intraocular lens design to harness the potential benefits of FLACS, and a reduction in cost are needed to establish a clear superiority over conventional phacoemulsification.

  4. The combination of intravitreal triamcinolone and phacoemulsification surgery in patients with diabeticfoveal oedema and cataract

    Cannon Paul S

    2005-06-01

    Full Text Available Abstract Background The management of diabetic patients with refractory macular oedema or patients with no adequate pre-operative view to administer laser treatment provide a challenge to the ophthalmologist. We wished to assess the use, safety and effect of intravitreal triamcinolone injection at the time of cataract surgery in patients with diabetic foveal oedema and sight limiting lens opacities. Method This was a longitudinal non-randomised prospective pilot study in 18 eyes (12 patients. All patients had visually significant lens opacities and either persistent diabetic foveal oedema unresponsive to laser treatment-group A, or foveal oedema with no adequate pre-operative view for laser treatment- group B. The cataract surgery was carried out under full aseptic technique using a self-sealing temporal incision and a foldable acrylic lens. Intravitreal triamcinolone was given infratemporally pars plana at the completion of the cataract surgery. The patients were reviewed at day 5, 2 weeks, 2 months and then every 3 months as required. The Wilcoxin matched-pairs test was used to assess the significance of the improvement in visual acuity at 2 months. Results Twelve patients with a total of 18 eyes were included in the study. There were 10 patients (15 eyes in group A and 3 patients (3 eyes in group B. Preoperatively 16 of the 18 eyes had a visual acuity of 6/24 or worse. Postoperatively 83% of patients had completely dry foveae at 2 weeks. Best-corrected visual acuities at two months review ranged from 6/6 to CF with 9 eyes (50% achieving 6/12 or better (7 eyes (47% in group A and 2 eyes (67% in group B. Three eyes had no recorded improvement in visual acuity, but no eyes had deterioration in acuity. The improvement in visual acuity was significant at p = 0.001. There were no significant sight threatening complications. Conclusion Intravitreal triamcinolone has been shown to lead to an improvement in macular oedema and visual improvement in

  5. Safety of undiluted intracameral moxifloxacin without postoperative topical antibiotics in cataract surgery.

    Zhou, Andrew Xingyu; Messenger, Wyatt Boyer; Sargent, Steven; Ambati, Balamurali Krishna

    2016-08-01

    The objective of this study is to evaluate the safety of undiluted 0.5 % intracameral moxifloxacin for postoperative endophthalmitis prophylaxis in cataract surgery patients without the use of additional postoperative topical antibiotics. All phacoemulsification cataract surgeries performed by a single surgeon (B.A.) at the John A. Moran Eye Center from June 2012 to May 2015 were reviewed retrospectively. From June 2012 to April 2014, patients were given topical 0.5 % moxifloxacin postoperatively. From May 2014 to May 2015, all patients were given moxifloxacin intracamerally with no antibiotics postoperatively. The follow-up period was 1 month after surgery. Preoperative visual acuity and postoperative visual acuity, corneal edema, and anterior chamber reaction were recorded and compared between the two groups. 384 cataract surgeries were performed during the study period. None of the 384 eyes in the study developed endophthalmitis. Of those 384 eyes, 222 were included in the study for analysis based on the inclusion and exclusion criteria. 131 were part of the topical antibiotic group and 91 were part of the intracameral group. The differences in uncorrected visual acuity at 1 day postoperatively (p = 0.595) and best corrected visual acuity at 1 month postoperatively (p = 0.099) were not statistically significant. Differences in corneal edema (p = 0.370) and anterior chamber reaction (p = 0.069) at 1 day postoperatively and corneal edema (p = 0.512) and anterior chamber reaction (p = 0.512) at 1 month postoperatively were also not statistically significant. Undiluted 0.5 % moxifloxacin can be safely injected intracamerally following cataract surgery without additional postoperative antibiotic prophylaxis to prevent endophthalmitis without adverse effects on patient outcomes.

  6. Telephone follow-up for cataract surgery: feasibility and patient satisfaction study.

    Hoffman, Jeremy J S L; Pelosini, Lucia

    2016-05-01

    Purpose - The purpose of this paper is to investigate the feasibility of telephone follow-up (TFU) after uncomplicated cataract surgery in low-risk patients and patient satisfaction with this alternative clinical pathway. Design/methodology/approach - Prospective, non-randomised cohort study. A ten-point subjective ophthalmic assessment questionnaire and a six-point patient satisfaction questionnaire were administered to patients following routine cataract surgery at two to three weeks post-procedure. All patients were offered a further clinic review if required. Exclusion criteria comprised ophthalmic co-morbidities, hearing/language impairment and high risk of post-operative complications. Patient notes were retrospectively reviewed over the study period to ensure no additional emergency attendances took place. Findings - Over three months, 50 eyes of 50 patients (mean age: 80; age range 60-91; 66 per cent second eye surgery) underwent uncomplicated phacoemulsification surgery received a TFU at 12-24 days (mean: 16 days) post-operatively. Subjective visual acuity was graded as good by 92 per cent of patients; 72 per cent patients reported no pain and 20 per cent reported mild occasional grittiness. Patient satisfaction was graded 8.9 out of 10; 81.6 per cent defined TFU as convenient and 75.5 per cent of patients preferred TFU to routine outpatient review. No additional visits were required. Research limitations/implications - Non-randomised with no control group; small sample size. One patient was unable to be contacted. Practical implications - Post-operative TFU can be suitably targeted to low-risk patients following uncomplicated cataract surgery. This study demonstrated a high patient satisfaction. A larger, randomised study is in progress to assess this further. Originality/value - This is the first study reporting TFU results and patient satisfaction to the usual alternative two-week outpatient review. PMID:27142949

    Wong, Margaret; Baumrind, Benjamin R; Frank, James H; Halpern, Robert L

    2015-01-01

    A 53-year-old Caucasian man underwent femtosecond cataract surgery and then presented with pain and hand motions vision 1 day following surgery. Anterior segment examination showed a 2-mm-layered hypopyon, a well-centered intraocular lens in the sulcus, and an obscured view to the fundus. B-scan ultrasonography showed significant vitritis and that the retina was attached. A tap and an injection of vancomycin 1 mg per 0.1 ml and of ceftazidime 2.25 mg per 0.1 ml were performed. The tap eventually yielded culture results positive for Staphylococcus haemolyticus, which was sensitive to vancomycin. We report a case of endophthalmitis that occurred on postoperative day 1 following complicated cataract surgery. This is an uncommon bacterium that is not widely reported in the literature as a cause of endophthalmitis in the postoperative period. We urge clinicians to consider S. haemolyticus as an offending agent, especially when the infection presents very early and aggressively in the postoperative period. PMID:26951642

    2015-01-01

    The introduction of femtosecond lasers is potentially a major shift in the way we approach cataract surgery. The development of increasingly sophisticated intraocular lenses (IOLs), coupled with heightened patient expectation of high quality postsurgical visual outcomes, has generated the need for a more precise, highly reproducible and standardized method to carry out cataract operations. As femtosecond laser-assisted cataract surgery (FLACS) becomes more commonplace in surgical centers, fur...

  10. Microbiological profile of anterior chamber aspirates following uncomplicated cataract surgery

    Prajna N

    1998-01-01

    Full Text Available Anterior chamber aspirate cultures were done for 66 patients who underwent either an uncomplicated intracapsular cataract extraction, extracapsular cataract extraction with posterior-chamber intraocular lens implantation, or phacoemulsification with posterior-chamber intraocular lens implantation. The aspirate was obtained at the time of wound closure. The aspirates were immediately transferred to the microbiology laboratory where one drop of the aspirate was placed on a glass slide for gram stain, and the remainder was unequally divided and inoculated into blood agar, chocolate agar and thioglycolate broth. The cultures were incubated at 37° C with 5% CO2 and held for 5 days. Of 66 patients 4 (6%, had smear-positive anterior chamber aspirates. None of the aspirates showed any growth on any of the 3 culture media used. None of the eyes in the study developed endophthalmitis. This study concludes that there is no contamination of the anterior chamber by viable bacteria after cataract surgery, irrespective of the mode of intervention.

    Full Text Available Pur po se: To evaluate the incidence of strabismus in pediatric cataracts and the effects of strabismus and nystagmus accompanied by cataract on postoperative visual acuity. Ma te ri als and Met hod: Seventy-four eyes of 45 patients under 15 years old who had undergone cataract operation were included in this study. The mean postoperative follow-up period was 1.57±2.25 years (ranged between 3 months and 9 years. Twenty-nine of the patients (64% had bilateral and 16 of the patients (36% had unilateral cataract. Preoperative and postoperative visual acuities, as well as the presence of nystagmus and strabismus were recorded. Re sults: Seventeen of the patients (38% had strabismus: 9 of them (53% had esotropia (ET, and 8 of them had (47% exotropia (XT. Fourteen (19% of the total number of cases had nystagmus. The mean age was 5.8±4.4 years for the total group of patients, 4.6±3.0 years for patients with strabismus and 5.1±3.7 years for patients with nystagmus. Visual acuity measurements were not possible in 26 uncooperative patients. The visual acuity was 0.3 logMAR and over in 15 (31% and 1.0 logMAR and under in 12 (25% of the remaining of 48 eyes. Of a total of 28 eyes with strabismus, we were unable to measure visual acuity in 10 patients, and the visual acuities were 0.3 logMAR and over in 7 (39% and 1.0 logMAR and under in 5 (28% of the rest of the 18 patients. The mean visual acuity was significantly lower in the 8 of 14 patients with nystagmus whose visual acuity could be measured (1.25±0.45 logMAR than in both the patients without strabismus (0.44±0.59 logMAR and the patients with strabismus (0.66±0.56 logMAR (p=0.019 and p=0.015, respectively. Dis cus si on: Although strabismus is seen more often in childhood cataracts compared to general population, the presence of strabismus has no negative effect on visual acuity after cataract surgery, while nystagmus is the main factor limiting the visual outcome.

  15. The challenges in improving outcome of cataract surgery in low and middle income countries

    Robert Lindfield

    2012-01-01

    Full Text Available Cataract is the leading cause of blindness globally and surgery is the only known measure to deal with it effectively. Providing high quality cataract surgical services is critical if patients with cataract are to have their sight restored. A key focus of surgery is the outcome of the procedure. In cataract surgery this is measured predominantly, using visual acuity. Population- and hospital-based studies have revealed that the visual outcome of cataract surgery in many low and middle income settings is frequently sub-optimal, often failing to reach the recommended standards set by the World Health Organization (WHO. Another way of measuring outcome of cataract surgery is to ask patients for their views on whether surgery has changed the functioning of their eyes and their quality of life. There are different tools available to capture patient views and now, these patient-reported outcomes are becoming more widely used. This paper discusses the visual outcome of cataract surgery and frames the outcome of surgery within the context of the surgical service, suggesting that the process and outcome of care cannot be separated. It also discusses the components of patient-reported outcome tools and describes some available tools in more detail. Finally, it describes a hierarchy of challenges that need to be addressed before a high quality cataract surgical service can be achieved.

DISCUSSÃO: Embora a cirurgia em catarata unilateral seja motivo de controvérsias entre os oftalmologistas, obteve-se melhora de acuidade visual em número significativo de casos.PURPOSE: To analyze the results in a series of children submitted to unilateral cataract surgery. METHODS: A retrospective study was conducted through the analysis of 35 patient files from the Congenital Cataract Service of UNIFESP/EPM. RESULTS: The main cause of unilateral cataract was idiopathic, the second cause was ocular trauma and the third cause was congenital rubella. Initial visual acuity was very poor in 51.4% of the cases (did not fix or follow, and the best corrected final visual acuity was better than 20/200 in 42.8% of the eyes. DISCUSSION: Although controversial, the surgical treatment of unilateral cataract, in this study, showed improvement in many cases.

    Full Text Available Background: Ultrasonography is an important tool for evaluating the posterior segment in eyes with opaque media. Aim: To study the incidence of posterior segment pathology in eyes with advanced cataract and to see whether certain features could be used as predictors for an abnormal posterior segment on ultrasound. Setting: Tertiary care hospital in South India. Methods and Materials: In this prospective study conducted over a 6-month period, all eyes with dense cataracts precluding visualization of fundus underwent assessment with ultrasound. Presence of certain patient and ocular "risk" factors believed to be associated with a higher incidence of abnormal posterior segment on ultrasound were looked for and the odds ratio (OR for posterior segment pathology in these eyes was calculated. Results: Of the 418 eyes assessed, 36 eyes (8.6% had evidence of posterior segment pathology on ultrasound. Retinal detachment (17 eyes; 4.1% was the most frequent abnormality detected. Among patient features, diabetes mellitus (OR= 4.9, P=0.003 and age below 50 years (OR= 15.4, P=0.001 were associated with a high incidence of abnormal ultrasound scans. In ocular features, posterior synechiae (OR= 20.2, P=0.000, iris coloboma (OR= 34.6, P=0.000, inaccurate projection of rays (OR= 15.1, P=0.002, elevated intraocular pressure (OR= 15.1, P=0.004, and keratic precipitates (OR= 22.4, P=0.004 were associated with high incidence of posterior segment pathology. Only four eyes (1.5% without these features had abnormal posterior segment on ultrasonography. Conclusions: Certain patient and ocular features are indicative of a high risk for posterior segment pathology and such patients should be evaluated by ultrasonography prior to cataract surgery. In the absence of these risk factors, the likelihood of detecting abnormalities on preoperative ultrasonography in eyes with advanced cataracts is miniscule.

    Purpose To evaluate the influence of biometric variables on refractive outcomes after cataract surgery in angle-closure glaucoma (ACG) patients. Methods In this case-control study, 42 ACG patients, 40 open-angle glaucoma (OAG) patients, and 35 controls without glaucoma who had undergone conventional cataract surgery were enrolled consecutively. Electronic medical records, including preoperative biometric variables (keratometric diopter, axial length, anterior chamber depth, and lens thickness), the refractive change (RC), and the absolute value of refractive change (ARC) were reviewed. Results In the control and OAG patients, the anterior chamber depth was negatively correlated with the ARC (r = -0.344, p = 0.043 and r = -0.431, p = 0.006, respectively), whereas there was no correlation in the ACG patients. Lens thickness was positively correlated with the RC, but not with the ARC, in the control and OAG groups (r = 0.391, p = 0.020 and r = 0.501, p = 0.001, respectively). In contrast, lens thickness in the ACG group was not correlated with the RC but was positively correlated with the ARC (r = 0.331, p = 0.032). Conclusions In contrast with the anterior chamber depth, preoperatively measured lens thickness may be a useful predictor of the direction of the RC after cataract surgery in control and OAG patients. However, in ACG patients, a thicker lens was correlated with a larger RC, regardless of the direction of the shift (hyperopic or myopic). PMID:27478355

  1. Small eyes big problems: is cataract surgery the best option for the nanophthalmic eyes

    Nanophthalmos refers to an eyeball of short axial length, usually less than 20 mm which leads to angle closure glaucoma due to relatively large lens. Intra-ocular lens extraction relieves the angle closure in nanophthalmos. Cataract surgery in a nanophthalmic eye is technically difficult with high risk of complications such as posterior capsular rupture, uveal effusion, choroidal haemorrhage, vitreous haemorrhage, malignant glaucoma, retinal detachment and aqueous misdirection. Various options are explained in the literature to perform cataract surgery in nanophthalmos, like extracapsular cataract extraction with or without sclerostomy; small-incision cataract extraction by phacoemulsification which not only helps maintain the anterior chamber during surgery but also reduces the incidence of complications due to less fluctuation of intraocular pressure (IOP) during the surgery. Cataract surgery deepens and widens the anterior chamber angle in nanophthalmic eyes and has beneficial effects on IOP in eyes with nanophthalmos but is associated with a high incidence of complications.

  3. Recognising ‘high-risk’ eyes before cataract surgery

    Full Text Available Certain eyes are at a higher risk of complication during cataract surgery. Operations on such ‘high-risk’ eyes are also more likely to yield a poor visual outcome (defined as best corrected vision less than 6/60 after surgery.1Learning to recognise when eyes are at greater risk, and acting accordingly, will help you to avoid complications. Even so, before the operation takes place, it is good practice to explain to such patients that a poor outcome is a possibility. This makes these patients’ expectations more realistic and improves postoperative compliance and follow-up. In most cases, patients who are blind with complicated cataract will be happy with even a modest improvement of their vision.It is also important to have available all the equipment you may need to manage a possible complication, for example a vitrectomy machine in the case of capsular rupture and vitreous loss.Depending on where you are in the world, certain ‘high-risk’ eyes will be more common: for example, pseudoexfoliation in Somalia and India, onchocerciasis in Sudan, and angle-closure glaucoma in Asia. You will get to know your local problems as you perform more operations.

    Full Text Available Purpose: To describe prophylactic patterns employed against endophthalmitis after cataract surgery in Iran. Methods: This cross-sectional study included 486 ophthalmologists filling in a self-administered questionnaire during the 20 th Annual Congress of the Iranian Society of Ophthalmology in December 2010, Tehran, working in both private and academic medical centers. Prophylactic measures used preoperatively, intraoperatively and postoperatively and self-reported rates of endophthalmitis were assessed as the main outcome measurements. Results: In the preoperative phase, 75.5% of surgeons used povidone-iodine in the conjunctival sac and 71.4% of them did not use antibiotics. The rate of intraoperative prophylaxis was 61.9% either in the form of intracameral antibiotics or subconjunctival injection (mostly cephazolin or gentamicin. Only 7.8% of participants used intracameral cephalosporins. Postoperative antibiotics [mostly chloramphenicol (57% and ciprofloxacin (28%] were used by 94.2% of surgeons. On average, ten years of practice were required to observe one case of endophthalmitis. Conclusion: The surgeons in present setting used various prophylactic regimens against endophthalmitis after cataract surgery. Setting a local and evidence-based clinical practice guideline seems necessary.

    The aim of this study was to investigate the clinical features and treatment results of endophthalmitis after cataract surgery. Five patients with endophthalmitis after phacoemulsification with intraocular lens implantation were enrolled in this study. The pathogenesis, clinical manifestation, and surgical outcomes of 5 patients were compared. Three patients were surgically treated with anterior chamber irrigation and vitrectomy with intravitreal injection. The remaining two patients were medically treated with an intravitreal injection of vancomycin and ceftazidime. Treatment results of the five patients were analyzed. Four patients had positive cultures for bacteria (two cases Staphylococcus epidermidis, one case Enterococcus faecalis, and one case head-like Staphylococcus). The culture of the fifth patient did not have bacterial growth. One year following treatment, four patients had restored visual acuity and a clear vitreous cavity. Retinal detachment and other complications were not observed. The remaining patient had a visual acuity of index at 30 cm one year following treatment. For patients with endophthalmitis after cataract surgery, a biochemical laboratory examination should be promptly performed and should include a bacterial culture and drug sensitivity test. When necessary, vitrectomy combined with an intravitreal injection of vancomycin should be performed to treat the infection early and to help retain useful vision. PMID:26125869

Specimens were collected by lightly rubbing the inferior palpebral conjunctival sac with a sterile cotton swab 2 weeks before surgery, and then cultured for isolation of bacteria and antimicrobial sensitivity testing. The bacterial isolates and percentage of drug-resistant isolates were compared among age groups and according to whether or not patients had diabetes mellitus, hyperlipidemia, dialysis therapy, oral steroid use, dry eye syndrome, or allergic conjunctivitis.Results: The bacterial isolation rate was 39.2%. There were 191 strains of Gram-positive cocci, accounting for the majority of all isolates (67.0%, among which methicillin-sensitive coagulase-negative staphylococci was the most frequent (127 strains, 44.5%, followed by methicillin-resistant coagulase-negative staphylococci (37 strains, 12.7%. All 76 Gram-positive bacillary isolates (26.7% were from the genus Corynebacterium. Among the 16 Gram-negative bacillary isolates (5.9%, the most frequent was Escherichia coli (1.0%. The bacterial isolation rate was higher in patients >60 years old, and was lower in patients with dry eye syndrome, patients under topical treatment for other ocular disorders, and patients with hyperlipidemia. There was no significant difference in bacterial isolation rate with respect to the presence/absence of diabetes mellitus, steroid therapy, dialysis, or

    Full Text Available Purpose: To determine the incidence of vitreous loss in patients undergoing cataract surgery and the visual outcome in a tertiary teaching hospital. Methods: Hospital records of 2095 consecutive patients undergoing cataract surgery between July 1999 and June 2000 were reviewed in this non-concurrent cohort study. Incidence and visual outcome of vitreous loss managed using standard vitrectomy techniques were assessed for different cataract surgical techniques (extracapsular, Blumenthal technique and phacoemulsification as well as at different levels of surgical training. The outcome was compared with matched cases without vitreous loss (controls. Results: Vitreous loss occurred in 160 of 2095 eyes (7.63%; CI -7 to 9.3: 8.3% for ECCE, 8.1% for the Blumenthal technique and 5% with phacoemulsification. Vision ž 6/18 was achieved in 85% of cases and 95% of controls. For experienced surgeons, 95% of the cases and controls had vision ž 6/18. 5.8 % of cases and 0.7% of controls had vision < 6/60. One patient in each group was blind following cataract surgery; both had operable cataracts in the fellow eye. Conclusions: The vitreous loss rate in this tertiary teaching hospital is relatively high. This complication, managed with standard surgical techniques, is compatible with good visual outcome. In eyes with vitreous loss, the final visual acuity achieved by experienced surgeons was similar to that in uncomplicated cases.
