Abstract: Purpose: To assess how preoperative clinical factors influence surgical outcomes following posterior-approach blepharoptosis repair. Design: Prospective cohort study. Methods: We conducted a prospective analysis of patients undergoing posterior-approach ptosis repair from 2022 to 2024. The primary outcome was change in marginal reflex distance 1 (ΔMRD1) at a 3-month follow-up. Secondary outcomes included inter-eye symmetry, contour, patient satisfaction (graded 0–2), surgery duration, and complication rates. We analyzed outcomes across three clinical subgroups: degree of ptosis (MRD1 ≥ 1 mm vs 8 mm vs 4–8 mm), and phenylephrine test result (positive vs negative). Results: A total of 231 eyes were included. Mean MRD1 improved significantly from 0.14 ± 1.5 mm preoperatively to 4.0 ± 0.8 mm postoperatively (P
