Intraocular lens implantation -- analysis of 500 consecutive cases.

The author analyzed 500 consecutive cases of intraocular lens (IOL) implantation performed in the past five years: the patients were unselected; 0.2% required enucleation (one case of epithelial downgrowth); 2% needed IOL removal; 3.6% suffered retinal detachment; males were three times as prone to retinal detachment and "vitreitis" as females; 7.5% experiences IOL subluxation; 10% required subsequent surgery for a variety of complications; 15% demonstrated clinical cystoid macular edema (CME); the lowest incidence of CME occurred with Copeland lenses (3.9%); the highest incidence of CME was seen with IOL's with metal loops (33%); 21% had CME following secondary implantation; 61% had no complications during surgery or the entire follow-up period. 79% had industrially-useful vision (20/40 or better); 95% had intracapsular extraction; there were no cases of endophthalmitis.
