Background: Posterior capsular opacity (PCO) is the commonest longterm complication of cataract surgery. PCO present with gradual decrease in visual acuity after successful cataract surgery. Various methods employed for the prevention of PCO like capsular polishing, implanting IOL’s with convex posterior surface and surface-modified lens have not been shown to be very successful in long term follow up. All my patients underwent Nd:YAG laser capsulotomy for Posterior capsular opacity, which is a noninvasive, effective and relatively a safe technique for PCO management.
Hence, in this present study every effort is made to study the visual outcome and IOP changes before and after Nd: YAG LASER capsulotomy.
Objective: To compare the visual outcome and IOP before and after ND-YAG laser capsulotomy in patients with Posterior Capsular Opacity
Methodology: A total of 100 patients with posterior capsular opacification attending the Department of Ophthalmology, Vinayaka Missions Medical College and Hospital, Karaikal who gave consent for the research purpose were taken up for the study. Patient’s details including age, sex, and surgical history was recorded. Complete Ocular examination was done before ND-YAG capsulotomy including Best corrected visual acuity (BCVA), Anterior segment examination using Slitlampbiomicroscopy, Retinoscopy, Intraocular pressure measurement using Applanation Tonometer and Posterior segment examination includes dilated fundus examination with Slitlamp biomicroscopy using +90D was recorded. Statistical analysis was performed using SPSS software.
Results: This prospective study was conducted in the Department of Ophthalmology at Vinayaka Missions Medical College, Karaikal. On approval by ethical committee, 100 patients with Posterior Capsular Opacification recruited after obtaining informed consent.The result of the study showed that, maximum number of patients had developed Elschnig pearl type of PCO i.e. 64 patients (64%). After 1 week ND YAG laser capsulotomy 84% (84 patients) of patients showed improvement in best corrected visual acuity. The results of the study showed that, all the 100 patients showed a temporary rise in the intraocular pressure values after ND YAG laser capsulotomy which return to near normal of the base line values at the 1 week of follow up.
Conclusion: The results of the study showed that Complications with Nd:YAG laser capsulotomy are very minimal and only transient elevation of IOP, which can be managed with topical Timolol maleate 0.5% drops on outpatient basis with regular follow up. Improvement in visual acuity with Nd:YAG laser capsulotomy is excellent and complications with Nd:YAG laser capsulotomy are minimal and transient in this study. Hence concluded that Nd-YAG laser capsulotomy is a noninvasive, effective, relatively safe technique to manage posterior capsular opacity and it does not require patient hospitalization.
