Clinical factors relating to cystoid macular edema after lens implantation.

Of 232 eyes undergoing intracapsular or extracapsular cataract extraction with implantation of a Binkhorst-style 2-loop lens, 46 (20%) developed persistent or transient clinical cystoid macular edema. The incidence of cystoid mascular edema was lowest when the posterior capsule and vitreous face were intact, and was unaffected by administration of prophylactic oral indomethacin.
