What is a cataract?
A cataract develops when the natural crystalline lens inside the eye becomes cloudy. It commonly develops in people over the age of 55 years and is considered a normal part of the aging process. Rarely some people can be born with cataracts or develop them before that age. Many patients who develop cataracts have otherwise healthy eyes and removing the cataract will restore their previously good vision.

How do I know if I have a cataract?
Patients with cataract usually find that their vision gradually becomes cloudy and blurred. They may also find that they experience glare when they are outside or looking at car headlights, which makes it difficult to see properly. Occasionally patients complain of seeing multiple images. Sometimes patients find that they need to change their glasses frequently. Cataracts are not painful.
The only effective treatment for cataracts is to operate to remove them. The modern technique for removing a cataract is called phacoemulsification surgery.
