Cataracts

Cataracts occur when the natural lens develops opaque or cloudy areas that prevent light from passing through to the retina properly. Cataracts may occur as a normal part of aging, or as a result of trauma. Treatment involves removing and replacing the lens with an artificial lens, called an intraocular lens (IOL.)

Cataracts develop slowly, so are not always apparent in their early stages. As proteins in the lens cohere to each other they begin to form cloudy areas that diminish visual clarity. This may seem, for a while, to be merely a need for “new glasses” with a stronger prescription. Over time they can develop into visible cataracts, for which the only treatment is removal of the eye's natural lens and the implantation of an artificial lens.

There are three types of IOLs and each has pros and cons. Crystalens®, an accommodating lens, moves under the control of your eye muscles. ReZoom® and ReSTOR® are multifocal IOLs, or fixed lenses. They don’t move within the eye. These use concentric rings of incremental focal power to allow good vision at various distances.

Older types of IOLs are still used occasionally. These are monofocal lenses that focus clearly at a single distance range. With the monofocal lenses you will need glasses to see at other distances.

Astigmatism can complicate IOL implant surgery, and cause the individual to need glasses for some or all activities. An alternative is to undergo a procedure to correct the astigmatism as well. Your eye surgeon can advise you of the most suitable options once he does a thorough eye exam.
