The Copeland intraocular lens: five to ten years later.

Fifty-seven eyes with extracapsular surgery and Copeland lenses and the same number of intracapsular cataract extractions without lenses are described. All properly chosen lens cases have 6/12 vision or better. Forty percent required capsulotomy because of 6/12 vision or less. Possible cystoid macular edema occurred in two cases. No endothelial changes were present that were not present preoperatively. Five lenses dislocated. Two glaucomas appeared. There was no retinal separation, endophthalmitis, or lens removal for lens-induced irritation.
