An intraocular lens (IOL) is an artificial replacement lens that is surgically implanted in the eye to replace the existing clouded lens during cataract surgery.
The good news is that you have developed cataracts at a time when intraocular lens technology is more advanced then ever. Traditionally, the replacement lens used for cataract surgery was a monofocal (single focus) IOL. People with monofocal IOLs still need glasses fro reading, or to correct astgmatism. The AcrySof IQ Toric IOL can correct astigmatism, and the AcrySof IQ Restor, or AMO ReZoom, can improve vision in a full range of distances.
