Blepharoptosis (ptosis) is the medical term for drooping eyelid. Ptosis surgery is designed to shorten and/or reattach the levator muscle tendon, the major muscle responsible for elevating the upper eyelid, to its normal location. The specific operation is based on the severity of the ptosis and the strength of the levator muscle. The main surgical goals are to restore the normal field of vision by elevating the upper eyelid and improve appearance by achieving symmetry with the opposite upper eyelid.
