Purpose: To investigate the association between cigarette smoking and cataract extraction in women. Methods: We examined the association between smoking and cataract extraction in a population based cohort of 35 376 women. Detailed information about diet and lifestyle factors was obtained through a self-administered questionnaire. During follow-up between September 1997 and December 1999, 853 women had a cataract extraction. Analysis was performed using Cox proportional hazard model. Results: We observed a 25% increased risk for cataract development among ever smokers compared to nonsmokers. (age adjusted rate ratio=1.25; 95% CI, 1.08-1.45). After additional adjustment for possible confounders (alcohol use, education, BMI, antioxidants) rate ratio was 1.18 (95% CI, 1.00-1.38). Conclusion: Cigarette smoking among women was associated with a moderately increased risk of cataract extraction. .
