Intraoperative Significance of Lower Eyelid Positions in Levator Advancement to Prevent Overcorrection

Abstract

Purpose:The purpose of this study was to investigate changes in the position of the upper and lower eyelids before and immediately after surgery in patients that underwent ptosis surgery. Methods:The authors retrospectively reviewed the clinical records of patients diagnosed with congenital or aponeurotic ptosis and that were treated with levator advancement with local anesthesia. The marginal reflex distance 1 (MRD1), marginal reflex distance 2 (MRD2), and palpebral fissure height (PFH) were measured using clinical photographs.
