Calcification of Intraocular Hydrogel Lens: Evidence of Dystrophic Calcification

Clinical and Experimental Ophthalmology, 2004
Abstract Purpose: To report and describe the surface calcification of three cases of implanted intraocular hydrogel lens. Methods: Three surgically extracted hydrogel intraocular lenses were studied by light and transmission electron microscopy as well as by energy dispersion X‐ray microanalysis.

The Potential Calcification of Octacalcium Phosphate on Intraocular Lens Surfaces

Journal of Biomedical Materials Research - Part A, 2004
AbstractRecently, calcification was observed on implanted intraocular lens (IOL) surfaces when viscoelastic substances were applied during surgery. To elucidate the mechanisms of mineral formation, the crystallization of calcium phosphates on IOL surfaces was studied in vitro with nanomolar sensitivity using a constant composition method.

Dystrophic Calcification of an Implanted Hydroxyethylmethacrylate Intraocular Lens

JAMA Ophthalmology, 1995
Hydroxyethylmethacrylate is a biomaterial still under clinical trial for use in foldable intraocular lenses. We observed a patient in whom a geographic opacification developed within an implanted hydroxyethylmethacrylate lens, together with granular deposits on the posterior lens capsule and in the scar of a paracentesis.
