An intraocular lens (IOL) is a clear, artificial lens for the eye. It replaces your eye’s cloudy natural lens when you have cataract surgery. There are different kinds of IOLs. A monofocal IOL is usually set for clear distance vision, with eyeglasses needed for reading or close work. Multifocal and accommodative IOLs provide clear vision at more than one distance. Toric IOLs correct the refractive errors that come with astigmatism.

Your ophthalmologist will discuss IOLs with you.
