Role of Preoperative Nd:YAG Laser Anterior Capsulotomy in Mature Intumescent Cataracts

Abstract

Purpose:The aim of this study was to examine the role of preoperative Nd:YAG laser anterior capsulotomy in preventing intraoperative complications in mature intumescent cataracts.Design:A prospective, interventional, observational study.Methods:A total of 52 eyes of 52 patients were selected in this prospective study. Preoperative Nd:YAG laser anterior capsulotomy was performed in all eyes with 1 shot of 1.2 mJ and a gush of the liquified cortex was noted. Anterior chamber depth was measured using anterior segment optical coherence tomography and intraocular pressure using Goldmann applanation tonometer were measured pre- and post-laser. Intraoperative complications and surgeon's operative comfort were noted.Results:There was a mean increase in anterior chamber depth by 0.24 mm and a mean decrease in intraocular pressure by 1.61 mm Hg postlaser. No intraoperative complications were noted except for capsulorhexis extension in 1 eye (1.92%). The surgeon experienced a good control while performing the capsulorhexis and overall an uneventful surgery.Conclusions:Preoperative Nd:YAG laser anterior capsulotomy is a safe and effective technique in reducing intralenticular pressure and avoiding intraoperative complications in mature intumescent cataracts.
