There are four options that surgeons currently use when doing clear lens exchange:
1. Implanting a traditional or monofocal lens in both eyes - This gives the patient the best corrected distance vision. The patient will require reading glasses after surgery for near work.
2. Doing a mono-vision correction - The second option is to use a traditional monofocal lens in both eyes, which means that the dominant eye (usually) is corrected for distance and the non dominant eye is under corrected so the patient can see up close.
3. Using multifocal lenses - These specialty intraocular lenses divide the light that enters the eye into two primary focal points. One is for distance vision; the other is for near vision. These lenses are good for patients who are motivated to have distance and near without glasses or mono-vision. There are two multifocal lenses on the market AcrySof ReSTOR and the ReZoom.
4. Using crystalens - Crystalens are the first of the accommodative lenses. This lens was approved by the FDA in 2005. Crystalens attempts to imitate the eye's natural accommodation by moving back and forth in the eye in a flexing motion in response to pressure inside the eye giving the patient distance and near in the same eye. This lens is also a possibility for CLE patients seeking distance and near without glasses or mono-vision.
When considering CLE ask your surgeon which of these lenses would work best for you.
