What is a cataract?

The lens of the eye is made mostly of water and protein. The protein is arranged to allow light to pass through and focus on the retina. Sometimes some of this protein clumps together, and starts to cloud a small area of the lens. This is a cataract. Over time, the cataract may grow larger and cloud more of the lens. Therefore, making it difficult to see.

Although researchers are learning more about cataracts, no one actually knows what causes them. Scientists think there may be several causes which may including; smoking and diabetes. Or possibly it’s just age related. Scientists do know that a cataract won’t spread from one eye to the other, although many people do develop cataracts in both eyes.

Cataract Surgery

This is a procedure of removing your lens from your eye. Usually the lens is then replaced with an artificial lens.

Normally, the lens of your eye is clear, but with cataract this causes your natural lens to become cloudy, which will then affect your vision.

After having cataract surgery, the patient is not required to remain in hospital and can leave after surgery. Cataract surgery can be done either by using ultrasound energy or either laser-assisted technology, to remove the cloudy lens. This surgery is very common and is generally a safe procedure.

Cataract vision

More than half of all the people age 65 and older have a cataract. In the early stages, stronger lighting may lessen the vision problems caused by cataracts. At a certain point, however, surgery may be needed to improve vision. Today, cataract surgery is safe and very effective.
