Evaluation of 50 silicone posterior chamber lens implantations

Abstract

This study presents our experience with 50 silicone intraocular lens (IOL) implants (STAAR Surgical Company, model AA-4004) in the posterior chamber. In the relatively short-term mean postoperative follow-up of seven months, the following complications were observed: iris chafing - pigmentary dispersion, 15 (30%); IOL tilt and decentration, 7 (14%); pseudophakodonesis, 6 (12%); fibrinous exudate, 3 (6%); luxation of one haptic in the anterior chamber, 1 (2%); IOL tears, 5 (10%). Visual acuity of 20/20 to 20/40 was obtained in 40 patients (80%). Although no severe consequences were noted, the long-term effects of the complications are unpredictable at present.
