Complications of silicone disc intraocular lenses

Abstract

Through a 4.5 mm comeoscleral incision, we implanted one of two types of foldable, silicone disc, posterior chamber intraocular lenses (IOLs) in the bag in 35 eyes of 32 patients after phacoemulsification and capsulorhexis. Five lenses were explanted in the early postoperative period because of complications. We followed 24 eyes for an average of 38 months. At the end of follow-up, 5 of the lenses had decentered by 1 mm; 8 (33%) had developed clinically significant posterior capsule opacification (PCO). We believe the IOLs' disc shape may not allow firm fixation, resulting in opacification. On average, there were no significant differences in long-term results between the two silicone disc lens types.
