The incision goes through the white part of the eye. Most of the time the healing is hidden so it can hardly be seen except with magnification. Later, rubbing does not seem to be a problem. Children usually do not rub their eyes, or when they do, the lids are tightly closed, thus preventing any eye damage. Generally, there is no immediately undesirable result from eye rubbing.
People are different.
Some are more sensitive to discomfort than others. Patients usually only require Tylenol for discomfort. There will also be some swelling and discharge after the surgery. The swelling should not be very much and the person should be able to open their eyes within the next 2 days, that is, the swelling should get less as each day goes by. If the swelling increases significantly, contact your doctor immediately, particularly if there is pain.
