title: Precipitation of calcium salts on a hydrophilic acrylic intraocular lens after a vitreous hemorrhage: case report and histopathologic correlation.
abstract: We describe the formation of calcium phosphate deposits on the external anterior surface of a single-piece foldable 26% hydrophilic acrylic intraocular lens (IOL) after vitreal bleeding. The IOL was explanted 20 months after uneventful phacotrabeculectomy because opacification was causing significant visual disturbance. Light microscopy and Raman spectroscopy of the explanted IOL showed that the opacification consisted of calcium phosphate on the IOL surface.
