IOL
Also written as: IOL — intraocular lens
Artificial lens implanted in the eye to replace the natural crystalline lens or correct refractive errors.
Full Definition
An intraocular lens (IOL) is a synthetic lens device that is permanently implanted inside the eye to replace the eye's natural crystalline lens when it has been removed during cataract surgery or to correct refractive errors without removing the natural lens. IOLs are typically made from biocompatible materials such as acrylic, silicone, or polymethylmethacrylate (PMMA). Various types include monofocal, multifocal, accommodating, and toric IOLs, each designed to address specific visual needs and correct different refractive errors including astigmatism.
Usage
Usage note: Always capitalize all letters when using the abbreviation IOL.
