Explantation of a glistening-free, hydrophobic acrylic intraocular lens with cosmetic imperfections on the lens surface

Abstract

The enVista intraocular lens (IOL), model MX60E is a single-piece hydrophobic acrylic lens that became available in early 2018. Several months later, certain lot numbers were recalled by the manufacturer due to reports of cosmetic imperfections on the IOL surface. We describe a case of an enVista IOL, model MX60E, exhibiting such cosmetic imperfections, which was explanted due to unwanted optical symptoms, from a patient with a medical history of sarcoidosis. Laboratory evaluation of the explanted lens revealed the presence of multiple concentric rings throughout the surface of the optic component, which appeared to correspond to manufacturing marks. The patient's undesired visual symptoms resolved after IOL exchange.
