A cataract is developed when the crystalline lens situated just behind the pupil that focuses light onto the retina becomes cloudy.
It reduces vision and causes glare from lights and images become hazy. When a cataract is formed, the incident light becomes blocked or scattered, causing blurry images and poor vision. As a part of the normal aging process or with other associated medical conditions, the lens in the eye can slowly become cloudy. This is called cataract. The risk of cataract increases with age. Cataract is very common but, luckily, in most cases also very easy to correct.
Cataract surgery, usually an outpatient procedure, takes an hour or less to perform.
First, your doctor will place eyedrops in your eye to dilate your pupil. You’ll receive local anesthetics to numb the area, and you may be given a sedative to help you relax. If you’re given a sedative, you may remain awake, but groggy, during surgery.
During cataract surgery, the clouded lens is removed, and a clear artificial lens is usually implanted. In some cases, however, a cataract may be removed without implanting an artificial lens
Typically patients will experience blurry vision, double vision, sensitivity to light, glare, colors that appear washed out, and frequent changes of eyeglass prescription. An ophthalmologist or optometrist will be able to diagnose a cataract by looking through a slit-lamp during a dilated eye examination or by looking through an ophthalmoscope.
