Cataracts are one of the most common eye conditions that can lead to a significant loss of vision. A cataract is the clouding of the eye's natural lens, which affects the clarity of your vision. This condition mostly affects older people, but it can occur at any age. Fortunately, with recent advances in technology, cataract treatment has become a highly successful procedure. What is cataract treatment? Cataract treatment is a surgical procedure that involves removing the clouded lens of the eye and replacing it with a clear artificial lens.
