This study evaluated whether applying a compression dressing to one eyelid after upper eyelid blepharoplasty (eyelid lift surgery) reduces swelling, bruising, and discomfort compared to the untreated eyelid. In this randomized trial, each participant underwent bilateral upper eyelid blepharoplasty; after surgery, one eyelid was randomly assigned to receive a compression dressing for 24 hours, while the other eyelid received no dressing and served as the internal control. Outcomes including eyelid swelling, bruising, pain, aesthetic appearance, and corneal health were assessed by masked observers on postoperative days 1, 7, 30, and 90. The goal of this study was to determine whether routine use of compression dressing provides a measurable clinical benefit after this common cosmetic and functional eyelid surgery.
