IOL Implants: Lens Replacement After Cataracts. An intraocular lens (or IOL) is a tiny, artificial lens for the eye. It replaces the eye's natural lens that is removed during cataract surgery. The lens bends (refracts) light rays that enter the eye, helping you to see. Your lens should be clear.
During cataract surgery, the natural clouded lens is replaced with an artificial lens called an intraocular lens (IOL). An IOL can not only restore vision lost to cataracts, but may also correct refractive errors such as nearsightedness (myopia), farsightedness (hyperopia), astigmatism or presbyopia.
