Precipitation of calcium salts on a hydrophilic acrylic intraocular lens after a vitreous hemorrhage: case report and histopathologic correlation.

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.

Report of a new family with dominant congenital heredity stromal dystrophy of the cornea.

Purpose: To report a new family with the rare form of congenital and hereditary stromal dystrophy of the cornea.

Methods: A mother and son, showing a bilateral congenital clouding of the cornea, were studied clinically and by biomicroscopy. After corneal transplantation, light microscopy and electron microscopy were performed.
