Comparison of Postoperative Pain With Two Different Types of Local Anesthesia in Surgery for a Drooping Eyelid

Conjunctival Mullerectomy is a well known procedure used to correct upper lid ptosis via a
posterior approach. Patients who undergo this procedure are often given local anesthesia to
alleviate intraoperative and postoperative pain. Local anesthesia can be given via frontal
nerve block or subconjunctival injection combined with sedation in most cases. Both
techniques are currently acceptable options for local anesthesia, however postoperative pain
has not been systematically evaluated between these two techniques.

The investigators aim to compare intra-operative and postoperative pain with these two
techniques in patients undergoing conjunctival Mullerectomy for ptosis repair. Patients will
be randomized to receive local anesthesia via frontal nerve block or via subconjunctival
injection. In addition, the investigators will measure the surgical outcomes of the ptosis
surgery with standard measures.
