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.

Objective: To determine the frequency of raised intraocular pressure in pseudophakic undergoing Nd YAG laser posterior capsulotomy. To compare the frequency of raised intraocular pressure in pseudophakic undergoing high and low energy Nd YAG laser posterior capsulotomy Methods: This Descriptive case series included 140 patients with pseudophakic posterior capsular opacity. After dilating the pupils with tropicamide Nd YAG laser posterior capsulotomy was performed and the total amount of energy used was noted. The frequency of raised IOP in post-laser patients and comparison of frequencies of raised IOP undergoing high and low energy Nd YAG laser posterior capsulotomies (≤ 50 MJ labeled as low energy and > 50 MJ labeled as high energy) were calculated Results: The mean age was 57.37 ±8.74. Mean pre laser IOP was 15.15 and post-laser IOP was 17.50. The rise in IOP was normal in 82.9% and raised in 17.1%. In lower energy group normal IOP was found in 35.7% and raised in 2.9%. In a higher energy group, normal IOP was found in 47.1%, and raised IOP was found to be 14.3%. Conclusion: Higher the energy used during the Nd YAG laser posterior capsulotomy procedure, more is the chance of a rise in post-laser intraocular pressure as compared to those in which lesser energy was being used.

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.

Purpose: To investigate the functional and structural recovery period of idiopathic epiretinal membranes after phacovitrectomy with posterior capsulectomy.Methods: From March 2012 to January 2015, 57 patients diagnosed with idiopathic epiretinal membranes with cataracts who underwent combined vitrectomy and cataract surgery with pars plana posterior capsulectomy were enrolled. The best-corrected visual acuity and central foveal thickness were analyzed retrospectively.Results: The average best-corrected visual acuity before surgery was 0.30 ± 0.23 logarithm of minimal angle of resolution (logMAR), and the mean central foveal thickness was 442 ± 93 μm. As of the 12-month follow-up, the average postoperative best-corrected visual acuity had improved to 0.08 ± 0.11 logMAR, and the central foveal thickness after surgery had decreased to 386 ± 58 μm at 12 months.Conclusions: After removing the potential influence of cataracts and posterior capsular opacity, the recovery of idiopathic epiretinal membranes continued up to 12 months after surgery.

Abstract Purpose To evaluate the necessity and safety of primary posterior capsulotomy during phaco-vitrectomy for idiopathic epiretinal membrane (ERM). Setting Seoul National University Bundang Hospital, Seongnam, Korea. Design Retrospective consecutive cohort analysis. Methods This study enrolled 219 patients (228 eyes) who underwent combined 25-gauge phaco-vitrectomy for idiopathic ERM and cataract, divided into capsulotomy (−) group (152 eyes, 144 patients) and capsulotomy (+) group (76 eyes, 75 patients). The main outcomes were rate of posterior capsular opacity (PCO) occurrence and postoperative complications. Ophthalmic examinations were performed at baseline, 1, 3, 6, and 12 months postoperatively. Results PCO only occurred in capsulotomy (−) group (20 eyes, 13.2%), with mean onset of 10.59 months. Visually-significant PCO that needed Nd:YAG posterior capsulotomy was present in 9 eyes (45.0% of PCO eyes). The rate of cystoid macular edema (CME) was higher in capsulotomy (+) group (6.6% vs. 15.8%, p = 0.026) with longer duration (1.50 vs. 3.36 months, p = 0.019). Female sex and posterior capsulotomy were significant risk factors for CME occurrence (p < 0.05). Conclusion Primary posterior capsulotomy during phaco-vitrectomy for idiopathic ERM obviated the need for Nd:YAG posterior capsulotomy, but visually-significant PCO that needed Nd:YAG laser was not common. Considering the low rate of visually-significant PCO and high rate of postoperative CME, routine posterior capsulotomy during phaco-vitrectomy may not be necessary for preventing PCO in ERM.

Posterior Capsular Opacity

Cataract is one of the most common ocular diseases in dogs, and phacoemulsification is considered its treatment of choice. Posterior capsular opacity (PCO) is a frequent complication and may occur weeks or months after the surgery. It is known that intraocular lenses (IOL) used for the correction of post-operative hypermetropia are an adjunctive aid in the prevention of PCOs, mainly the foldable acrylics designs with square and truncated edges. However, IOL placement may result in endothelial cell loss. This study evaluated the morphology and cellularity of the endothelium by non-contact specular microscopy in aphakic and pseudophakic dogs. Endothelial cell density, endothelial cell area, coefficient of variation and hexagonal cells percent were analyzed for each group and between groups. During all evaluation periods, endothelial cell density did not alter in any group. From days 7 to 30, endothelial cell density was higher in pseudophakic dogs. However, values returned to normal and, by the end of the study, no significant difference was observed. Cell area and variation coefficient did not differ in each group or between groups. Hexagonal cells percent significantly reduced after phacoemulsification in both groups. With time, this condition returned to initial values. When both groups were compared, hexagonal cells percent were decreased in the pseudophakic group, immediately after the surgeries.
