Eyelid surgery is often considered for problems affecting both the upper or lower eyelids. In the upper eyelids, excessive upper eyelid skin can either give patients a sad look, or can hang down and impair vision. In the lower eyelids, bags under the eyes can give patients a tired appearance. Excess eyelid skin is removed during the procedure, and the underlying tissue can be repositioned to improve the overall appearance. This procedure can be performed on the upper lids, lower lids, or both.
Ptosis vs. Dermatochalasis
Ptosis occurs when the eyelid is low and the margin of the lid is sitting at or below the upper edge of the pupil. This is due to a stretched or weakened levator muscle. Surgery to correct this can be done from either inside/underneath the eyelid, or through the skin at the lid crease.
Dermatochalasis is when you have excess skin and fat in the upper lid, which may be treated with a blepharoplasty. A blepharoplasty is done to remove to skin and excess fat.
Patients with ptosis frequently have excess skin, and in those cases both ptosis repair (to tighten the muscle) and blepharoplasty are done at the same time.
