The clouded lens is removed in a surgical procedure. It usually takes about 20 to 30 minutes and is commonly done on an outpatient basis. An intraocular lens (IOL) is placed in the eye to replace the eye’s natural lens. Usually, patients will go home the same day as their cataract surgery with a patch and a shield covering the eye. They will come back the next morning to see the doctor. The patient will wear the shield at night for another week and will be given some sunglasses to be worn as needed. A regimen of drops will be prescribed.
