MedicalResearch.com: What are the main findings of the study?
Answer: We have investigated the association between smoking cessation and risk of having a cataract extraction among 44 371 Swedish men aged 45-79 years. During 12 years of follow up we identified 5713 incident cases of cataract extraction.
Smoking cessation significantly decreased the risk with time.
Men who currently smoked more than 15 cigarettes per day had a 42 % increased risk of cataract extraction compared with men who had never smoked.
More than 20 years since quitting smoking, men who had smoked more than 15 cigarettes per day had a 21% increased risk of having a cataract extraction compared with men who had never smoked.
The effect of smoking cessation was observed earlier among men who smoked less than 15 cigarettes per day but more than 2 decades since smoking cessation the risk had not decreased to the level of never smokers.
