This document provides information about cataracts and cataract surgery. It defines a cataract as a clouding of the lens of the eye that causes blurry vision. Risk factors for developing cataracts include older age, UV exposure, steroid or drug use, and diabetes. Symptoms include blurry vision, impaired night vision, faded colors, glare sensitivity, and halos around lights. Cataract surgery is a painless outpatient procedure where the cloudy lens is removed and replaced with an artificial lens to improve vision. Recovery from surgery involves some initial blurry or wavy vision that improves over days, brighter color perception, and follow-up visits with the doctor.
