Purpose. To evaluate the analgesic efficacy of 0.5% propacaine hydrochloride as topical anesthesia during phacoemulsification\nsurgery. Methods. Intraoperative pain intensity was assessed using a 5-category verbal rating scale during each of three surgical\nstages. Pain scores from each surgical stage and total pain scores were compared for the factors of patient age, gender, cataract\nlaterality, and type. Results. In comparison of cataract type subgroups, the mean total pain scores and mean stage 2 pain scores in\nboth white mature cataract (WMC) and corticonuclear plus posterior subcapsular cataract (CN + PSC) groups were significantly\nhigher than in the PSC-only (PSC) group (???? < 0.05). Conclusion. Phacoemulsification with topical anesthesia is not a completely\npainless procedure. Pain intensity varies with cataract type and stage of surgery.
