Introduction: Preexisting posterior capsular opacification is commonly seen in the developing world due to late presentation of patients for cataract surgery. Patients are implanted with either hydrophilic or hydrophobic IOL. Effect of these IOLs on pre-existing posterior capsular opacification has not yet been reported.Aim: To determine the incidence of peripheral preexisting posterior capsular opacity (PPPCO) in patients undergoing cataract surgery and the rate of posterior capsular opacification (PCO) following implantation of hydrophilic and hydrophobic intraocular lens (IOLs).Study design: Prospective, observational case study Setting: Tertiary eye care center in central India. Methodology: 1400 consecutive patients undergoing phacoemulsification of senile cataract between July 2009 and June 2010 discovered to have PPPCO were included in the analysis. Patients were either implanted with hydrophilic (n= 40) or hydrophobic IOL (n=40). Images of the posterior capsule immediately and 3-years postoperatively were compared. Patients were followed up for development of PCO, visual outcome at 3 years and neodymium: YAG laser posterior capsulotomy (NYLPC) rate.Results: Eighty patients were found to have PPPCO (incidence of 5.7%). 47.5% of PPPCOs were from mature senile cataracts (n = 38), 36.2% were from posterior subcapsular cataracts (n = 29) and 16.2% were from posterior polar cataracts (n = 13). NYLPC was performed in 9 patients receiving hydrophilic (22.5%) and 3 patients receiving hydrophobic IOLs (7.5%; p = 0.12). Average time to NYLPC was 18 months in the hydrophilic and 30 months in the hydrophobic group (p = 0.002). Visual outcome was satisfactory at 3-years of follow-up.Conclusion: PPPCO is a frequent occurrence in mature cataract and there is a higher incidence of PCO in PPPCO patients implanted with hydrophilic IOL than with hydrophobic IOL. Therefore, hydrophobic IOL should be considered for patients discovered to have PPPCO during cataract removal.

Introduction: Lens Induced Glaucoma (LIG), is one of commonest cause of secondary glaucoma due to senile cataracts. The purpose of this study was to see the outcome of cataract surgery in patients with LIG. Methods: This was a prospective case series of 40 patients with LIG who presented to our hospital between April to June 2014. The purpose of this study was to look into the age and sex distribution, causes for delayed presentation, immediate post-operative visual outcome and the reasons for poor visual outcome. Result: There were 23 phacomorphic cases and 17 phacolytic glaucoma patients included in our study. The mean age at presentation was 63±10 years. Female to male ratio was 2.1:1. The majority of patients 57% presented after 2 weeks of symptoms and the reason for late presentation in more than half of the patients (52.5%) was financial constraints. At presentation, mean preoperative intra ocular pressure was 39±10 mm Hg. Following surgery, 36 of 40 eyes (90%) had an IOP less than 21 mm Hg at discharge. Visual acuity was either hand-movement or just perception of light in all eyes before surgery. At discharge, 26 of 40 operated eyes (65%) achieved 6/60 or better, 2 (5%) had less than 6/60 and 12 (30%) less than 3/60. The reasons for poor VA in these 12 patients were optic atrophy in 5 patients, uveitis in 5 patients, macular cause in one and corneal edema in one. Conclusion: Cataract surgery proves to be effective in lowering the Intraocular pressure and visual recovery in patients with lens induced glaucoma.

Background: Posterior capsular opacification (PCO) which is also known as “after cataract” or “secondary cataract”, is the most common complication of cataract surgery, with an incidence of 20-50%. The current study was conducted in a tertiary hospital of Odisha with an objective to find out the determinants of PCO among patients with defective vision attending the outdoor patient department of Ophthalmology.Methods: A hospital based descriptive study was conducted among the patients attending the ophthalmology out patient department of a tertiary hospital of Odisha. The detail history regarding the type of surgical procedure used for cataract extraction and the type of Intra Ocular Lens (IOL) implanted, duration of post-operative period was collected from the available documents and ophthalmic examination of the participants.Results: In the present study, 184 participants were included and examined. Fifty percent of the participants had undergone conventional extra capsular cataract extraction procedure. In 86.95% participants, the IOL used was Poly Methyl Methacrylate lens (PMMA). In 26.08% of the participants the development of PCO was within 12 to 36 months of cataract surgery. The average duration of PCO development recorded for participants <20 years was 3 months.Conclusions: Most of the participants included in the study with PCO had undergone conventional ECCE surgery, implanted PMMA lens, IOL with round edge and had a duration of 12-36 months between cataract surgery and PCO development. The average duration of PCO development is less among younger participants which gradually increases with increase in age.

Introduction: Cataract is most common cause of curable blindness worldwide and cataract surgery is most common procedure performed in ophthalmology. Posterior capsular opacification (PCO) is most common complication after cataract surgery which is usually treated with Neodymium-doped: Yttrium Garnet (Nd:YAG) laser posterior capsulotomy or occasionally with a surgical capsulotomy. The incidence and severity of PCO correlates to the type of surgical technique, IOL optic edge designs and IOL materials. Material and Methods: 70 eyes of 64 patients operated for age related cataract were studied in this prospective interventional study. Phacoemulsification was done in 35 eyes and SICS in 35 eyes with hydrophobic single piece biconvex foldable intraocular lens. Patients were followed up at 1, 3, 6, 9 and 12 months for the development of PCO. Clinically significant PCO (loss of 2 or more lines of Snellen’s visual acuity chart) was treated with Nd:YAG laser capsulotomy. Results: The overall incidence of PCO was 22.85%. Amongst the patients who developed PCO, SICS and phacoemulsification was performed in 62.5% and 37.5% patients respectively. Result was statistically significant with p value <0.05 using z test. On first postoperative day, patients operated with phacoemulsification had better visual acuity than SICS. Conclusion: Phacoemulsification can provide early and better visual outcome than SICS and has lower incidence of PCO formation which may be due to difference in irrigation and aspiration and less disruption of blood aqueous barrier than SICS. PCO can be reduced by atraumatic surgery and thorough cortical clean up and capsular polishing.

Purpose. To determine and to analyze the outcome of pediatric cataract surgery. Methods. A retrospective chart review of individuals aged up to 10 years who underwent cataract surgery between January 1, 2004, and December 31, 2014, at the UniversityHospital Zurich, Switzerland. Results. 63 children (94 affected eyes) with bilateral (68/94) or unilateral (26/94) cataract were identified. Surgery was performed at a median age of 1.5 months (IQR: 1.3–2.6 months) for the aphakic group (45/94) and of 50.7 months (IQR: 38.0–78.4 months) for the IOL group (49/94). At the last follow-up visit (median 31.1 months, IQR: 18.4–50.2 months), visual acuity was better in bilateral than in unilateral cataract cases. Posterior capsular opacification (PCO) was diagnosed in 30.9% of eyes without a significant difference in the IOL and aphakic groups (p=0.12). Aphakic glaucoma was diagnosed in 12/45 eyes at a median of 6.8 months (IQR 2.1–13.3 months) after surgery. Microcornea (5/12) and anterior segment anomalies (8/12) were associated with glaucoma development (p<0.05). Conclusion. Laterality and timing of surgery influence the outcome of pediatric cataract surgery. PCO was the most frequent postoperative complication. Aphakic glaucoma is often associated with ocular developmental abnormalities and a poor visual outcome.

The comparative efficacy of trifocal and bifocal intraocular lenses (IOLs) remained uncertain among patients undergoing cataract surgery. A systematic review and meta-analysis was performed to answer this question. PubMed, Cochrane Library and Embase were searched to capture relevant randomized controlled trials (RCTs). Visual acuity (VA) and patient's satisfaction were regarded as primary outcomes. Secondary outcomes included residual sphere, spherical equivalence, residual cylinder, posterior capsular opacification (PCO), spectacle independence, and other complications. Statistical analysis was done using RevMan 5.2.0. A total of 9 studies (11 RCTs) with 297 participants (558 eyes) were included. Meta-analysis showed significant differences between trifocal and bifocal IOLs in the uncorrected near VA (mean difference [MD], −0.008; 95% confidence interval [Cl], −0.015 to −0.001; P = 0.028) and uncorrected intermediate VA (MD, −0.06; 95% CI, −0.10 to −0.02; P &lt; 0.01). Trifocal IOLs were associated with decreased PCO incidence when compared to bifocal IOLs (relative risk [RR], 0.54; 95% CI, 0.31 to 0.95; P = 0.03). Trifocal IOLs may be superior to bifocal IOLs because of its improved intermediate VA and reduced incidence of PCO.
