Cataracts

A cataract is a clouding of the lens of the eye which leads to a decrease in vision. Cataracts often develop slowly and can affect one or both eyes. Symptoms may include faded colours, blurry or double vision, halos around light, trouble with bright lights, and trouble seeing at night.


Most cataracts develop when ageing or injury changes the tissue that makes up your eye's lens. Some inherited genetic disorders that cause other health problems can increase your risk of cataracts. Cataracts can also be caused by other eye conditions, past eye surgery or medical conditions such as diabetes.


Surgery is necessary when the cataract begins to interfere with daily activities. Ordinarily, a person doesn’t have to wait until the cataract is mature for sight to be restored. Cataract is treated with a straightforward, 20-30 minute surgery, performed by an ophthalmologist. Surgery involves removing the cloudy lens tissue, and replacing the natural lens with an implant called an intraocular lens (IOL).


The power of the implant is calculated individually for each eye, so the image for distance is brought to focus on the retina and the person is able to see clearly within a few hours after surgery. Medication and care is required for a few weeks till the eye is completely healed.
