General anesthetics normally are used to produce loss of consciousness before and during surgery. However, for obstetrics (labor and delivery) or certain minor procedures, an anesthetic may be given in small amounts to relieve anxiety or pain without causing unconsciousness.
The type of anesthesia you have will depend on your general health. In most cases you will remain awake and aware throughout your procedure. You will be given medication by mouth to help you relax during your surgery. An IV may be started for additional medication if any is needed. Before you are taken into surgery, drops will be instilled in your eye to numb the eye.
