Brief Summary
Blepharoptosis (ptosis) repair is a common and generally well tolerated surgical procedure usually performed using local anesthetic. However, a subset of patients appears to experience intraoperative pain/discomfort during ptosis repair using an anterior approach with subcutaneous local anesthetic. Posterior subconjuctival local anesthetic is currently used for eyelid procedures such as chalazion incision and drainage and full-thickness eyelid resections. The purpose of this study is to determine whether an additional subconjunctival injection of local anesthetic, through the posterior aspect of the eyelid, reduces intraoperative pain during anterior ptosis repair.

Outcome Measures
Primary Outcomes (1)
0-10 Numerical Pain Scale
Patients will be asked to describe the intraoperative pain they experienced in each eye during surgery. Results will be compared with McNemar's test.
6 Years
Secondary Outcomes (2)
Presence of post-operative lagophthalmos/fluorescein staining
6 Years
Post-Operative margin-reflex distance 1
6 Years
Study Arms (2)
Subcut. + Subconj. Injection
EXPERIMENTALPatients will undergo standard blepharoptosis repair using an anterior approach, with an added injection of local anesthetic (Xylocaine) beneath the conjunctiva of the lid being operated on. They will still receive the standard subcutaneous local anesthetic given during blepharoptosis repair.
Subcut. + Sham Subconj. Injection
SHAM COMPARATORPatients will undergo standard blepharoptosis repair using an anterior approach, however they will not receive the additional subconjunctival Xylocaine injection. Instead, they will receive a sham injection of Normal Saline to prevent them from knowing which eye received the additional anesthetic.
Interventions
Patient will receive the standard subcutaneous local anesthetic as well as an additional subconjunctival injection of local anesthetic (Xylocaine).
Patient will receive the standard subcutaneous local anesthetic as well as a subconjunctival sham injection of Normal Saline.
Patients will undergo blepharoptosis repair using an anterior approach.
Eligibility Criteria
You may qualify if:
- Must be 18 years of age or older and able to give informed consent in English
- Must have bilateral blepharoptosis undergoing repair using an anterior approach
- The degree of ptosis must be approximately symmetrical, with a difference in margin-reflex distance of 1 mm or less between the two sides
You may not qualify if:
- Previous eyelid surgery or trauma
- Congenital, mechanical, myogenic or neurogenic forms of ptosis
- Unable to give informed consent
