A cataract is clouding or opacity of the lens inside the eye. It causes gradual blurring of vision and often glare.
When cataract develops, the lens becomes cloudy and prevents the light rays from passing on to the retina. The picture that the retina receives becomes dull and fuzzy.
Cataract in the main form slowly and most people experience a gradual blurring of vision.
Most forms of cataract develop in adult life. The normal process of ageing causes the lens to harden and become cloudy. There are other types, including congenital (present at birth), drug induced (steroids), and traumatic (injury to the eye). Cataract is also more common in people who have certain diseases such as diabetes
Treatments for cataracts is an operation to remove the cloudy lens and replace it with a clear artificial replacement. This treatment is quick, and can greatly improve vision. If left untreated, a cataract can restrict daily activities and affect your quality of life. Modern cataract surgery not only aims to restore better quality vision but also reduce your dependence on glasses for a significantly improved quality of life.
