Abstract

Purpose: To compare pain sensation induced by phacoemulsification with topical anesthesia with that by peribulbar anesthesia, without sedation. Methods: Using a 10-level visual pain analogue scale, the pain induced by phacoemulsification with topical anesthesia (2% tetracaine drops) was measured in 20 patients. The same scale was used to measure the pain induced by peribulbar anesthesia (2% lidocaine and 0.5% bupivacaine) in 21 patients. The same surgeon performed peribulbar infiltrations and surgeries. The phacoemulsifications were done using clear corneal approach followed by in-the-bag intraocular lens implantation. Pain comparison between the two groups was performed by the non-parametrical U Mann-Whitney test. Results: The distribution of the pain scores of the patients who underwent cataract extraction with topical anesthesia ranged from 0 to 5 (median value = 2). The scores of the patients who underwent peribulbar infiltration ranged from 0 to 7 (median value = 3). The mean rank of the group of patients who had surgery with topical anesthesia (15.78) was significantly different from the mean rank of the patients who received peribulbar anesthesia (25.98) (p=0.0057). Conclusion: Without sedation, the pain induced by phacoemulsification with topical anesthesia was milder than the pain induced by peribulbar infiltration.
