Abstract
Capsulotomy and the risk factors associated with it. After four years of follow-up, 21% of all cases had developed pearling. Over the same period, the probability of pearling, as determined by the Kaplan-Meier curves, was 29% with a 95% confidence interval between 22% and 36%. After one year of follow-up, the probability of pearling was 5%; after two years, 15%; after three years, 24%. Younger age (50 years or less), larger optic, and smaller IOL were identified as significant risk factors when each of these factors was analyzed separately. When all risk factors were studied together, and after applying confounding statistics, only younger age was identified as a significant risk factor (P = .003). 1Reprint requests to Dr. Leon D.
