[Aspirin in the preventive treatment of cataract].

In the patients with rheumatoid arthritis treated for a long time with aspirin, the percent of cataract is very low. Three action ways of aspirin were formulated in hindering the appearance of cataract: 1) acetylation of the lens proteins; 2) decrease of glycemia and 3) decrease of triptophen amount in the blood plasma. The lab experiments plead for these hypotheses. For preventing cataract, the persons with high risk of cataract and with incipient signs of opacity are recommended a daily and long treatment with 1/2 buffered and effervescent aspirin tablet, or 1 tablet at two days, under careful ophthalmologic surveillance.
