Cataract is the leading cause of blindness in the developing world, statistics showing that as much as sixty two percent of blindness is caused by cataract. But this figure, although seems worrisome, does not stem from the seriousness of the disease, rather it is due to lack of access to basic health facilities for majority of the population in developing countries.
Nowadays, cataract has been looked upon as an inevitable age change rather than a disease. And it is completely treatable with a very good vision after surgery, owing to the advancing techniques and technology which have surfaced in recent times.
What is Cataract ?
Our eye is provided with a clear transparent structure, the lens. It focuses the incoming light rays from the outside on to the retina (a highly sensitive layer which sends visual signals to the brain). Thus a normal functioning, clear lens is essential for good eyesight.
When, due to any cause, most usual being increasing age, any opacity occurs in the lens, it is termed cataract. Initially posing no problems, it progresses and may cause complete loss of sight.
