Methods: The study was a community-based cross-sectional study done at field practice area of rural health training centre and urban health training centre, J N Medical College, AMU, Aligarh, Uttar Pradesh, India. A sample of 550 was taken from the registered elderly population aged 60 years and above using systematic random sampling with PPS. Socio- demographic characteristics was obtained using pretested and predesigned questionnaire. Cataract was identified with the help of torch light examination of lens. Data was analysed using SPSS version 20. Tests of proportion (Wald’s method to calculate confidence interval) and chi-square test was used. P value <0.05 was considered as significant.

Results: The prevalence of cataract in the study population was 72.1% (95% CI- 68.3%, 75.8%) which was significantly associated with age, marital status, type of family & working status.
