Role of Nd: YAG Laser in Visual Outcomes and IOP Changes pre and Post Nd: YAG Laser Capsulotomy

Abstract

Background: Posterior capsular opacification (PCO, secondary cataract, after cataract) is a post-surgical complication following cataract surgery. PCO results from the migration and proliferation of residual lens epithelial cells onto the central posterior capsule, leading to decreased visual function. Neodymium Yttrium Aluminium Garnet (Nd: YAG) LASER (light amplification by stimulated emission of radiation) Capsulotomy is one of the most common procedures for PCO following cataract surgery due to its non-invasive nature, immediate recovery and is an OPD procedure. Objective: To observe the role of Nd: YAG laser capsulotomy in terms of visual outcome (Best Corrected Visual Acuity) and the changes in IOP and other complications after the procedure. Material and Methods: A hospital-based, observational, prospective study was carried out at R. M. Kedia Eye Hospital from July 2018 to June 2019. 200 eyes of 200 patients with PCO were included in the study. Complete ocular examination including visual acuity (VA), anterior and posterior segment examination with a slit lamp, and IOP measurement using Goldmann applanation tonometer were performed pre and post-laser in all cases.
