A cataract is a common haze or opacity that develops in the human lens. It is one of them most frequent causes of reduced vision and is associated with difficulty seeing details and glare at night. Fortunately, when indicated, cataract surgery can greatly improve vision by removing the cataractous lens and replacing it with a clear implant. Recent innovations now allow implants to correct for astigmatism and reading glasses.
Cataract surgery involves removing the cloudy lens of the eye with a small ultrasonic vacuum probe and replacing it with a clear intraocular lens. The procedure is done using a high power microscope while you are under a light sedation.
