Iris prolapse in small incision cataract surgery

Iris prolapse is a rare complication after small incision cataract surgery. We looked at the possible operative and perioperative factors that might have contributed to this complication in 2 of our patients and in another 10 patients identified through a national questionnaire survey. The details of 12 cases of iris prolapse following small incision cataract surgery are presented. Since iris prolapse may occur in small incision cataract surgery, notably in the presence of certain predisposing factors, extra diligence is required in wound construction and closure in high-risk patients.
