Cataract surgery is a relatively simple and straightforward procedure. In most cases, only local anesthesia is necessary, and patients can go home the same day. In fact, the procedure itself only takes about 30 minutes. Doctors may restrict a patient from performing certain activities for a couple of days following surgery, such as bending or lifting. Eye drops may be given to prevent infection and protective eye gear may need to be worn.
