Epithelial downgrowth is a serious complication of intraocular surgery
. It is characterized by the diffuse or cystic proliferation of surfac
e epithelium inside the eye. Advances in microsurgical technique that
result in smaller surgical wounds and permit greater precision in woun
d closure should reduce the incidence of this complication. We report
a case of epithelial downgrowth presenting 3 years after an uncomplica
ted clear-corneal catarct extraction with insertion of a posterior cha
mber silicone lens. The epithelial downgrowth was amenable to surgical
correction because the well-defined cyst could be excised en bloc.
