Cataract & Cataract Surgery
Cataract occurs when the natural lens of the eye, which is normally clear, becomes cloudy. A cloudy lens, like a dirty camera lens, produces a blurred image, causes glare and may cause a change in an eyeglass prescription. In some cases a simple eyeglass change may dramatically reduce symptoms from cataract. If visual symptoms from cataract are intolerable or interfere with normal daily responsibilities or activities, one might consider cataract surgery. Cataract surgery is almost always elective and rarely medically necessary. Failure to have cataract surgery will not cause irreversible damage to the eye. Poor vision and other symptoms from cataract almost always worsen with time. Fortunately, cataract surgery can completely restore normal vision provided the remaining eye structure is normal. Delaying cataract surgery for years, however, may make removal more difficult causing delayed visual recovery especially in elderly individuals.
Cataract surgery involves anesthetizing the eye with a local anesthetic either applied as a topical eye drop or as an injection into the lower eyelid. The surgeon enters the eye with tiny instruments and removes the clouded natural lens of the eye, replacing it with a clear silicone or acrylic artificial lens. The lens lasts a lifetime with no adverse effects (rejection) if it is properly implanted.

Standard Cataract Lens Options
With the standard lens option there are three choices. In the first option the operated eye would be placed in focus for distance. With this option one would be able to see clearly in the distance with both eyes and would wear glasses for all near tasks such as reading. With option number two the operated eye would be placed in focus for normal reading distance (2-3 feet away). With this option one would be able to read without glasses but would require glasses to see clearly in the distance for tasks such as driving and most sports. The last option would place one eye in focus for near and the other eye in focus for distance.(The so-called monovision option). Not everyone is a good candidate for monovision. Monovision is a good option for individuals who have been utilizing monovision successfully with contact lenses prior to surgery. Monovision slightly impairs depth perception and can be a problem when driving at night.
With all of the above mentioned options, clear distance or near vision is only possible if the patient has little or no astigmatism. If significant astigmatism is present clear vision will not be possible for either distance or near without glasses unless provisions are made to correct the astigmatism at the time of cataract surgery or later by the use of laser vision correction.

Multifocal and Accomodating Lenses
The new multifocal intraocular lenses have different zones of focusing power in the same lens. In general, the zones closer to the center of the lens focus light for near vision and the peripheral zones focus light for distance vision. The most popular example of such a lens is the Alcon Restor intraocular lens.
The latest generation of accommadating lenses is best represented by the Crystalens. The Crystalens is different from Multifocal lenses in that it has only one power thoughout the lens. However, Inside the eye the lens is believed to change its focusing power by changing its position during near vision tasks in the same way that the natural lens of the eye achieves near vision.
If the eye has significant astigmatism intraocular lenses are now available to correct this optical aberrration. Astigmatism is accurately measured prior to surgery and a formula is used to select the appropriate lens for correction.
All of the options above are reviewed during consultation.
