Purpose: Conjunctival Muller's muscle resection (CMMR) is a posterior approach surgical technique to correct blepharoptosis. The purpose of this study is to compare patient-reported pain scores and surgical outcomes for patients who received 2 different anesthetic techniques during CMMR, frontal nerve block and subconjunctival injection. Methods: A prospective randomized comparative clinical trial enrolled 33 CMMR subjects from one tertiary eye center. Patients undergoing unilateral CMMR were randomized to receive either frontal nerve block or subconjunctival injection. For patients undergoing bilateral CMMR, each side was randomized to one of the injection techniques. Upper eyelid margin reflex distance was measured and recorded for each eye before and after surgery. Patients' pain scores were quantified using the Wong Baker Pain Scale. Subjects quantified their pain during, immediately after, 12 and 24 hours after surgery. Results: Twenty-four bilateral and 9 unilateral cases were enrolled in the study. Twenty-two (92%) subjects were female, and the mean patient age was 69 ± 12 years. The mean margin reflex distance was 1.1 mm preoperatively, which increased to 3.5 and 3.6 mm 2 months postoperatively in frontal nerve block and subconjunctival injection groups, respectively (p value
