A cataract is a clouding of the natural lens, the part of the eye responsible for focusing light on the retina and producing clear, sharp images. Old cells in the lens die and become trapped in the sealed lens capsule, accumulating until light passing through the lens scatters, resulting in a blurry or fuzzy image. Contrast sensitivity is reduced, as if you were always trying to see in dim light.
In the past people waited until their cataract was fully “ripe” and nearly blinding before having it removed, the current recommendation is to have the surgery as soon as a cataract interferes with normal activities, including driving, watching television, climbing stairs, playing tennis, cooking and reading. In fact, the more advanced a cataract becomes, the more difficult the surgery.
The surgery to remove the cataract involves a very small self-healing incision in the cornea — less than one- eighth of an inch, or 3 millimeters, and no stitches needed — through which a tiny probe is inserted that transmits ultrasound waves to break up the cataract. The emulsified lens is then suctioned out through the probe.
The clouded lens that is removed is replaced with an individually fitted artificial lens that can result in near-perfect visual acuity — the ability to see distance. Or for those who prefer a correction of near vision for reading, an artificial lens can do that instead. For some people, even a multifocal lens can now be fitted, to improve both near and far vision.
If you or someone you know has a cataract or is need of cataract surgery and lens implants please feel free schedule a cataract evaluation at Eye Center of Texas by calling 713-797-1010.
Cataract surgery…is nothing short of amazing.
