dc.description.abstractOBJECTIVE: To determine the association between cataract surgery and age-related macular degeneration (AMD) in a representative US sample. DESIGN: Population-based, cross-sectional study. SETTING: The US National Health and Nutrition Examination Survey 2005-2008. PARTICIPANTS: A total of 5401 participants aged ≥40 years had information in cataract surgery status and gradable retinal photographs for right eyes. METHODS: Cataract surgery status was obtained from questionnaire. Non-mydriatic fundus photographs were collected and AMD status was assessed. The associations between AMD and cataract surgery were evaluated in right eyes using logistic regression models. RESULTS: Of 338 right eyes with any AMD, 107 right eyes (28.9%) had cataract surgery. After adjusting for multiple variables, there were significant associations between cataract surgery and any AMD (OR 1.36; 95% CI 1.03 to 1.81) or late AMD (OR 2.48; 95% CI 1.01 to 6.09). No significant association was found between cataract surgery and early AMD after adjusting for multiple covariates (OR 1.20; 95% CI 0.91 to 1.59). CONCLUSION: Our results suggest that cataract surgery is associated with the presence of AMD, particularly for late AMD. Longitudinal studies investigating the risk and progression of AMD after cataract surgery are needed in the era of phacoemulsification.
