A cataract reduces quality of vision due to the "clouding up" of the eye's lens. Normally, light passes through the eye's lens and pupil, hitting the retina at the back of the eye. But, when the lens becomes cloudy, the image that reaches the retina is dull and blurred, which results in poor vision.
The cloudiness that is a cataract is caused by a chemical change in the lens itself. Cataracts are usually the result of the natural aging process but can also result from injury or eye infections. The onset of vision loss is gradual and may be hard to notice at first-cataracts can take months or years to fully form. If left untreated, cataracts can lead to blindness.
Cataracts typically cause no symptoms until they become large enough to blur light coming through the eye's lens. Once symptoms do develop, they may include:
The only way to counteract the cloudy vision caused by a cataract is to remove the cataract surgically. This surgical procedure removes the natural lens of the eye and replaces it with a permanent artificial lens. DeHaven uses the highest quality lenses available including ReSTOR® and TORIC brands of intraocular lenses. The removal of the clouded lens from the lens capsule uses the technology of Phacoemulsification, whereby an ultrasound breaks up and removes the cataract. The artificial or intraocular lens can then be put into place. Phacoemulsification, and its use of ultrasound technology, remains the quickest and most proven option for removal of cataracts.
