Abstract
- Purpose To assess the risk of advanced age-related macular degeneration (AMD) developing after cataract surgery. Design Cohort study. Participants Four thousand five hundred seventy-seven participants (8050 eyes) from a multicenter, controlled, randomized clinical trial, the Age-Related Eye Disease Study (AREDS). Methods Development of advanced AMD, either neovascular (NV) AMD or geographic atrophy (GA), was evaluated with annual fundus photographs, and history of cataract surgery was assessed every 6 months. Cox proportional hazard models with time-dependent covariates were conducted for NV AMD and GA separately. Main Outcome Measures Neovascular AMD, GA, and central GA (CGA; involving the center of the macula). Results The Cox proportional hazards model of right eyes showed nonsignificant hazard ratios of 1.20 (95% confidence interval [CI], 0.82–1.75) for NV AMD, 0.80 (95% CI, 0.61–1.06) for GA, and 0.87 (95% CI, 0.64–1.18) for CGA. Similar results were obtained for left eyes: 1.07 (95% CI, 0.72–1.58) for NV AMD, 0.94 (95% CI, 0.71–1.25) for GA, and 0.86 (95% CI, 0.63–1.19) for CGA. For participants with advanced AMD in 1 eye (AREDS category 4), the hazard ratios for fellow eyes were 1.08 (95% CI, 0.65–1.72) for NV AMD and 0.98 (95% CI, 0.64–1.49) for CGA. Conclusions The AREDS results showed no clear effect of cataract surgery on the risk of progression to advanced AMD.
