Association of statin use with cataracts: a propensity score-matched analysis.

Importance: Cataracts are a main cause of low vision; with the growing elderly population, the incidence of cataracts is likely to increase. Investigators have previously hypothesized that statin antioxidant effects may slow the natural aging process of the lens.

Objective: To compare the risks for development of cataracts between statin users and nonusers.
