title: [Late opacification of a polymethylmethacrylate (PMMA) intraocular lens: case report].
abstract: The use of intraocular lenses was a great advance in visual recovery after cataract surgery. Although usually with good biocompatibility, some alterations in the intraocular lens material may occur after implantation. Polymethylmethacrylate was the first intraocular lens material to be used on a large scale and assumed to be inert and well-tolerated. We present a rare case of late opacification of a polymethylmethacrylate lens, discussing important aspects of its management such as the indication for intraocular lens exchange.
