Why Is Blepharoplasty Done?
Blepharoplasty is done to improve visual function and/or cosmetic appearance.

Excessive upper eyelid tissue can block the upper part of the visual field. This can be determined by lifting the upper lids with your fingers to see if the upper visual field improves or vision brightens. A formal visual field test may be helpful in this situation. The weight of the excess tissue may cause brow ache and fatigue. Occasionally, the excess skin can cause eye lashes to turn in and irritate the eye.

An excessive number of wrinkled skin folds above the eyes can produce a sagging tired look which detracts from one's general appearance. In this situation, blepharoplasty may be considered for cosmetic reasons even though vision is not affected. Cosmetic eyelid surgery is one of the most common plastic surgery operations performed by ophthalmologists.

Why Is It Important To Consult An Ophthalmologist When Considering Blepharoplasty?
Because blepharoplasty can affect the function and lubrication of the eye, a consultation with an ophthalmologist is important. Although other surgeons may perform blepharoplasty, an ophthalmologist is the only surgeon trained specifically to treat the eye. Therefore, he or she is uniquely qualified to help you decide whether you should consider this surgery.

How Is Eyelid Surgery Performed?
After the amount of skin and fat to be removed has been determined, upper and lower incision lines are marked along natural skin creases. Incision lines generally extend into the "crow's feet" or "smile lines" at the outer edge of the eye, so that once healed, the incision lines are less visible. The excess skin and fat are removed, and the incisions are sutured closed. The procedure is performed with local or general anesthesia depending on individual preference and health factors.

What Results Can I Expect?
Generally results are successful. However, surgical outcome will depend on the extent of corrective work, the skin structure and healing process, hereditary factors, age and other physical characteristics. As with any surgical procedure, an element of risk exists. Hemorrhage, infection, or even blindness, though rare, may occur.
