Efficacy of Primary Posterior Curvilinear Capsulorhexis in Adults

Abstract

Posterior capsular opacification(pco) is the most frequent complication of cataract surgery anddevelops from residual lens epithelial cells that undergo proliferation,migration,metaplasia and differentiation in the capsular bag after cataract surgery.patients with PCO have decreased visual visual acuity, loss of contrast sensitivity, and in some cases, PCO precludes examination of the posterior segment. The incidence of PCO is reported to be 20-50% 5 years after cataract surgery in the general population and has been reported to occur in 100% of pediatric patients. Recently, primary posterior capsulorhexis (PPCC) has been proposed to prevent PCO in adults. The PPCC technique is frequently used in children with or without anterior vitrectomyto prevent posterior capsule opacification (PCO) but is rarely used in adults. In PPCC, the central portion of the posterior capsule is removed during cataract surgery to prevent equatorial LEC migration toward the visual axis. Aim: The aim of the current study was to report the long-term efficacy and safety of phacoemulsification and manual phaco with posterior chamber intra ocular lens implantation combined with PPCC in adult patients with cataract. Materials And Methods: In an interventional case series 100 patients underwent cataract surgery combined with PPCC at Rajiv Gandhi Institute of Medical Sciences Kadapa, Andhra Pradesh from August 2014 to June 2016. Informed consent was obtained from all patients preoperatively. Only adult patients who underwent cataract surgery and PPCC for age-related cataract were included the study. Inclusion Criteria: Although we do not routinely perform PPCC during cataract surgery in adults, it is performed for cases with residual posterior capsule opacification despite careful polishing. Excleusion Criteria: Patients with glaucoma, uveitis, zonular weakness, and proliferative diabetic retinopathy were excluded in this study. Patients with clear posterior capsule were also excluded.
