Sagging or drooping eyelids occur naturally with increasing age. However, some people are born with it or develop diseases (such as myasthenia gravis ) that cause eyelid drooping. Most blepharoplasties are done to improve appearance, but some people have excessive eyelid drooping that actually interferes with vision. For these people blepharoplasty is required to improve eyesight. When done for cosmetic purposes, eyelid repair is considered elective surgery. It is usually done while the patient is awake or sleepy (sedated) but under local anesthesia. The incisions are made in the natural creases or folds of the eyelids. Loose skin and extra fat tissue is removed. The eyelid muscles are tightened and the incision is stitched closed. Eyelid repair surgery rarely requires hospitalization. The surgery is done in a surgeon's office or as outpatient surgery in a hospital or surgical center.
