To perform upper eyelid surgery, Dr. Sherman first measures the excess skin and marks the incision sites within the natural creases of the lids. Using this incision location ensures that these creases will hide scar tissue. After making incisions along the eyelids, Dr. Sherman removes excess fat, muscle tissue, and loose skin. Then, she uses fine sutures to close the incisions, thereby further minimizing the visibility of scar tissue. During lower eyelid surgery, Dr. Sherman makes incisions either behind the eyelid (the "hidden incision" or transconjunctival blepharoplasty technique) or along the lower eyelash line. Then, she trims away excess fat, muscle, and skin before closing the incisions with self-dissolving sutures. Most blepharoplasty procedures take just one to two hours to perform, depending on the complexity of the operation.
