Failed PC-IOL implantation in one eye and successful AC-IOL implantation in the other eye in a patient with pre-existing bilateral uveitis.

An irregular proteinaceous film populated by sessile macrophages and large giant cells was found on the surface of a posterior chamber lens implant. This had to be removed from a position with its haptics in the capsular bag 8 months after surgery because of increased uveitis. The implant had been placed at the time of extracapsular cataract extraction in a patient with pre-existing active bilateral chronic iridocyclitis of a non-granulomatous type. An anterior chamber lens implant placed after intracapsular cataract extraction in the other eye of the same patient was tolerated, and the same type of implant was used to replace the removed posterior chamber lens implant.
