The investigators propose a prospective randomized control trial testing the hypothesis that routine topical antibiotic prophylaxis does not significantly reduce the rate of infection after eyelid surgery.

Official Title

The Role of Topical Antibiotic Prophylaxis in Eyelid Surgery


The use of prophylactic topical antibiotic therapy after eyelid surgery is widespread. Due to increasing antibiotic resistance, antibiotic-related complications, and healthcare costs, the investigators wish to determine whether prophylactic post-operative antibiotic ointment is truly necessary. After all, existing dermatology literature currently recommends against the routine use of antibiotic ointment after various surgical procedures (e.g. Mohs surgery). The investigators aim to perform a prospective randomized control trial at the University of California, San Francisco. The investigators aim to recruit a total of 400 oculoplastics patients undergoing eyelid surgery or surgery involving peri-orbital incisions from 2017 through 2019.
