title: Early opacification of a single-piece hydrophobic acrylic intraocular lens after a triple procedure.
abstract: We report a case in which the optic of a single-piece AcrySof acrylic (SA60AT, Alcon) intraocular lens (IOL) became opacified. A 64-year-old man had a triple procedure of vitrectomy, phacoemulsification, and IOL implantation for cataract and a dense vitreous hemorrhage in the left eye. The IOL was clear on the day after surgery, but by the third day, a dusty haze was observed on the surface due to the presence of numerous, small brown corpuscles. The IOL was removed and replaced with another SA60AT. No optic opacification occurred on the replacement IOL. Analysis of the explanted IOL indicated the presence of proteinaceous material but no calcium on the surface. Early postoperative opacification of a single-piece acrylic SA60AT IOL might occur in combined cataract and vitreous surgery, even in eyes in which the posterior capsule is intact and there are no operative complications.
