After a local anesthetic is applied to the eye, do not rub or wipe the eye until the anesthetic has worn off and feeling in the eye returns.

Modern anesthetics can be divided into several different groups according to how and where they act to reduce pain.

During premedication, the anesthetist may give a patient drugs that make him or her feel relaxed and drowsy before the actual general anesthetic is administered.
