What is an IOL?
An intraocular lens (IOL) is the replacement lens that is surgically implanted in the eye to replace the existing clouded lens during cataract surgery. Cataract and lens implant surgery today is highly successful and very precise.
Standard Monofocal IOLs
A monofocal IOL is a fixed lens (it doesn’t move) that is designed to deliver improved vision at just one distance (usually far). The potential drawback is that after surgery, you will probably need to wear glasses for near vision, even if you didn’t wear glasses before surgery.
A multifocal lens uses multiple visual zones that are built into the lens itself to provide vision at various distances. It’s almost like the rings of a target, with some rings being dedicated to distance vision, while others are used for near vision, similar to having a bifocal or trifocal lens inside the eye. There are presently three brands of Multifocal IOLs to choose from: ReZoom™, ReSTOR®, and Tecnis®.
As the name implies, an accommodating lens “flexes” or “accommodates” to focus on subjects at various distances, delivering a continuous range of vision at near, intermediate and far. Crystalens® is the first and only FDA-approved accommodating intraocular lens.
