Cataract surgery removes the lens of the eye, where cataracts grow, therefore, it is impossible for cataracts to grow back. However, there is a such thing as “secondary cataracts”. This occurs when leftover epithelial cells accumulate in the posterior lens capsule, creating a scar like tissue that affects your vision, similar to the symptoms of cataracts. Secondary Cataracts are treated with a YAG laser capsulotomy, a simple outpatient procedure that can be completed within minutes.
