Rate of retinal tear and detachment after neodymium:YAG capsulotomy

Abstract

Purpose: To determine the rate of retinal tear and retinal detachment (RD) after neodymium:YAG (Nd:YAG) laser capsulotomy for posterior capsule opacification (PCO) after cataract surgery.

Setting: Province-wide outpatient and hospital settings, Alberta, Canada.

Design: Database study.

Methods: Eleven years of billing records data were collected to assess the rate of retinal tear and/or RD after Nd:YAG laser capsulotomy. A period of 90 days from Nd:YAG was considered the at-risk period, although statistics for 10 years of data were included in the study. Risk was calculated as a rate (%) of retinal tear or RD after Nd:YAG laser capsulotomy.

Results: The study comprised 92 654 discrete billing records yielding 73 586 ocular procedures for the analysis of the rate of retinal tear and/or RD after Nd:YAG laser capsulotomy. There were 67 287 Nd:YAG capsulotomies for PCO performed during the study. The 90-day risk for retinal tear after Nd:YAG was 0.21%; 720 retinal tears occurred in the study population at some point after the procedure. The rate of RD was 0.60%, with 2219 RDs occurring at some point after Nd:YAG capsulotomy. The cumulative risk for retinal tear or detachment at 3, 6, 9, and 12 months was 0.21%, 0.30%, 0.36%, and 0.43% and 0.60%, 0.96%, 1.19%, and 1.39%, respectively. The rates of retinal tear and detachment varied significantly between age categories.

Conclusions: There was an increased risk for RD in the first 5 months after Nd:YAG, with a return to a baseline plateau thereafter. As such, the rate of retinal tear after Nd:YAG capsulotomy at 5 months was 0.29%, whereas the rate of RD was 0.87%.
