A refractive surgical procedure that is commonly used to treat patients with cataracts. The procedure has been modified to also correct nearsightedness in high prescription ranges and most ranges of farsightedness. During the lensectomy procedure, the natural lens (crystalline lens) is extracted and an artificial lens is implanted. The power of the artificial lens is determined preoperatively during the full eye examination. There is minimal discomfort and visual recovery is very rapid.
Presbyopia is the age-related loss of the ability to focus up close to read. New implants developed for use after cataract surgery can to a large extent reverse these changes and allow independence from glasses after surgery. Three of these implants (IOLS) are now approved by the FDA.
The crystalens IOL is the only accommodative IOL available in the U.S. that is designed to provide a continuous range of vision for distance, intermediate and near. Near and intermediate vision result from the action of the focusing muscle in the eye, called the ciliary muscle. This movement of the lens enables the eye to focus at distance, intermediate and near to reduce your need for glasses after surgery. Clinical research shows that 73% of people with the crystalens in both eyes never or only rarely wear glasses. .
The ReZoom is a multifocal IOL. That means that it provides multiple focal points so you can see well at a variety of distances. It allows most people to see well at near, intermediate and distance. The ReZoom Multifocal lens is divided into five different zones with each zone designed for different light and focal sources at night. A clinical study has shown that 93% of people with the ReZoom in both eyes never or only occasionally wear glasses..
The ReSTOR IOL uses multifocal diffractive technology to give a full range of vision (near, intermediate and distance) that increases independence from glasses. Its unique design means that in bright light when the pupil is constricted incoming light is equally divided between near and distance vision for better reading, and when the pupil is enlarged as when driving at night, incoming light is focused almost entirely for distance. Multifocal IOLs do have the potential to produce halos around light sources at night. A clinical study has shown that 76% of people with the ReSTOR in both eyes never wear glasses..
Medicare does not fund the additional cost of these newest types of implants and related services. However, Medicare patients are now allowed by Medicare to purchase these for an additional price so that they may enjoy the advantages of theses presbyopia correcting IOLs following cataract surgery.
