Cataract is a common problem especially in the older age group. Approximately one third of those aged 65 or above have cataracts in either one or both their eyes. Age-related cataracts are responsible for 48% of world blindness, which represents about 18 million people.
What are the symptoms of age-related cataracts?
During the early stages, a change in glasses and brighter lighting may help to improve vision. However, as cataracts continue to progress and opacify, vision becomes cloudy and stronger glasses or contact lenses will no longer improve sight.
Top three symptoms of cataract:
1. Cloudy or blurry vision.
2. Glaring of sunlight or automobile headlights (especially night driving).
3. Dulled colour vision.
Cataract symptoms are usually gradual, painless, and not associated with any eye redness. Only if the cataract becomes very mature may the individual experience severe eye pain, redness, and headache.
When do you require a cataract surgery?
Traditionally, surgery is advocated when the cataract becomes mature or “ripe”. Today, with the advances in the surgical techniques and intraocular lens technology, cataract surgery can be performed as soon as your vision affects daily activities (such as driving, reading, computing, watching TV, etc.). There is no medication that can reverse the effects of cataracts; surgery remains the only way to restore good vision.
