Cataract surgery is a common and safe procedure used to treat cloudy vision caused by cataracts. During the surgery, the cloudy lens in the eye is removed and replaced with a clear artificial lens. This helps restore clear vision and usually takes less than an hour. Most people experience little discomfort and recover quickly, often seeing better within a few days. Cataract surgery is one of the most effective ways to improve eyesight and quality of life for those affected.
