What is Cataract?

A cataract is a clouding of the eye's natural lens, leading to blurry vision, glare, and eventual vision loss if untreated. It is most commonly age-related, affecting over half of people by age 80, but can also result from injury or medical conditions. Cataract surgery, which replaces the cloudy lens with an artificial intraocular lens (IOL), is one of the safest and most effective surgeries worldwide, with a success rate above 98%.
