PG - 478-487 LID - S0161-6420(22)01017-X [pii] LID - 10.1016/j.ophtha.2022.12.022 [doi] AB - PURPOSE: To estimate the incidence and assess the risk factors associated with 3 adverse events (AEs) after neodymium:yttrium-aluminum-garnet posterior capsulotomy (Nd:YAG-caps): ocular hypertension (OHT), macular edema (ME), and retinal detachment (RD). DESIGN: Observational cohort study using a nationwide claims database. PARTICIPANTS: Adults who underwent Nd:YAG-caps between 2014 and 2017, with no ocular disease history in the year before. METHODS: Patients who underwent Nd:YAG-caps were identified using data from the French national representative sample and followed up for 12 months postprocedure. The time to AE was assessed using the Kaplan-Meier method. Factors associated with AE were assessed using Cox models. MAIN OUTCOME MEASURES: Neodymium:YAG-caps epidemiology, patients' characteristics, proportion of patients with AE, and hazard ratios (HRs) associated with variables identified as factors associated with AEs. RESULTS: During the study period, 6210 patients received Nd:YAG-caps (7958 procedures). The mean age (+/- standard deviation) at Nd:YAG-caps was 75.0 (+/- 10.3) years. The 3-month and 12-month overall AE rates (>/= 1 AE of interest) were 8.6% and 13.3%, respectively. Among patients with >/= 1 AE of interest, 68.4% of AEs occurred within 3 months post-Nd:YAG-caps. Three-month rates were approximately 5% for OHT and ME. Retinal detachment remained
