Cataract surgery typically takes an hour or less to complete as an outpatient treatment. Your eye will first be dilated with eyedrops by your doctor. Local anesthetics will be used to numb the region, and you could also be given sedatives to make you more comfortable. If a sedative is used, you can be sleepy but awaken during operation. The clouded lens is removed during cataract surgery, and a clear prosthetic lens is often placed in its place. However, there are rare circumstances when a cataract can be eliminated without the use of an artificial lens. The lens of your eye is removed during cataract surgery, and in most cases it is replaced with an artificial lens. Your eye's lens is usually transparent. The cloudiness of the lens brought on by a cataract eventually impairs vision. Ophthalmologists (eye doctors) do cataract surgery on an outpatient basis, so you don't need to stay in the hospital following the procedure. Surgery to remove cataracts is quite frequent and often safe.
