Cataractogenic factors in patients with primary angle-closure glaucoma after peripheral iridectomy.

In this retrospective study we evaluated 154 patients with primary angle-closure glaucoma operated on by peripheral iridectomy to determine the factors contributing to the high occurrence (57%) of cataracts. Cataract formation in an eye operated on by peripheral iridectomy was age-dependent and less related to the time after surgery. The acute attack enhanced the appearance of the lenticular changes but did not influence the overall occurrence of cataracts in older patients.
