Smoking contributed to the occurrence of cataracts in smokers, but what the risk is if someone quit smoking? By answering these questions, researchers from Sweden collected data from 44 371 men aged 45 to 79 years. During the 12-year study period, as many as 5,713 men apparently had cataract surgery. Researchers then studied the relation between the number of cigarettes smoked per day by the number of cataract operations that occur.
They conclude, a person who smokes 15 cigarettes per day 42 percent higher risk of cataracts than those who had never smoked. Quitting smoking does reduce the number of these risks, however-even after 20 years-the risk remains higher when compared with nonsmokers. Through this study, the researchers emphasize how important it is to quit smoking since the early-or even not smoking at all.
