We examined three cases of transcorneal extrusion of anterior chamber intraocular lenses. In each case a preexisting condition (rheumatoid arthritis, glaucoma, and herpes zoster ophthalmicus, respectively) contributed to corneal necrosis and subsequent extrusion of the pseudophakos. The clinicopathologic correlations of this condition are discussed, as well as some causes of corneal decompensation associated with anterior chamber lenses. We emphasize the need for careful evaluation of patients who have preexisting disease before intraocular lens implantation.
