Intraocular lens (IOL)

An intraocular lens, or I-O-L, is the artificial lens implant that replaces the eye’s natural lens after cataract surgery. Recent advancements in lens technology have made it possible to not only treat the cataract, but to reduce or eliminate dependence on glasses as well. In most cases the patients have reported having the best vision of their lives.

Since no single lens works for everyone, there are four major types of I-O-Ls produced, they are: Monofocal, Multifocal, Accommodative, and Toric. Each lens is made of materials such as soft silicone or acrylic, and is approximately a quarter of an inch in diameter.

During cataract surgery a local anesthesia is administered. The surgeon will make a small incision in the eye, and the I-O-L is gently unfolded and placed behind the iris. In most cases the patients are able to go home the same day.

The procedure of cataract removal and I-O-L implantation has one of the best success rates of all surgeries. But with all surgeries, it is important to know the risks, and discuss the options with your eye care provider to help you determine the most appropriate treatment option for you.
