Official Title: Subconjunctival Injection of Local Anesthetic in Anterior Blepharoptosis Repair

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.

Detailed Summary:
Sponsor: University of Manitoba

Current Primary Outcome: 0-10 Numerical Pain Scale [ Time Frame: 2 Years ]

Patients will be asked to describe the intraoperative pain they experienced in each eye during surgery. Results will be compared with McNemar's test.


Original Primary Outcome: Same as current

Current Secondary Outcome:

  • Presence of post-operative lagophthalmos/fluorescein staining [ Time Frame: 2 Years ]
    The presence or absence of lagophthalmos and fluorescein staining will be assessed in each eye at the post-operative follow up appointment, and will be compared with McNemar's test.
  • Post-Operative margin-reflex distance 1 [ Time Frame: 2 Years ]
    Post-operative margin-reflex distance 1 (MDR1 - distance between the pupillary light reflex and the lower edge of the upper lid) will be measured in each eye. The difference between the MDR1 of each eye will be analyzed using paired Student's T-testing.


Original Secondary Outcome: Same as current
