Background: Cataract is a common and correctable ophthalmological condition that is associated with a poor quality of life and shortened life expectancy in older people. However, little is known regarding the use of cataract surgery in stroke patients after the incident event. Methods: A national cohort of 5462 patients who had experienced an acute stroke event without severe physical disability between 2000 and 2003, and 26,434 randomly selected age- and sex-matched controls were obtained from a random population-based sample of the National Health Insurance database in Taiwan. Multivariate Cox proportional hazard regression analysis was used to assess the association between stroke events and cataract surgery. Results: After a 5-year follow-up, 482 stroke patients (8.8%) and 1897 controls (7.2%) had received cataract surgery after the index dates of their stroke. The incidence of subsequent cataract surgery following acute stroke was 27% higher than that in the comparison group (crude hazard ratio 1.27; p < 0.001). Adjusted for age, sex, co-morbid medical diseases, use of systemic steroids, exposure to radiation during computed tomography, and socioeconomic status, the incidence of cataract surgery in the stroke patients was 30% higher than that in the comparison group (adjusted hazard ratio 1.30; p < 0.001). Conclusion: A 30% increase in the use of cataract surgery was noted among the survivors of acute stroke with mild-to-moderate disabilities, which may result from the increased need for better vision after stroke.
