| Abstract | Background: Topical anesthetics have become the primary choice in phacoemulsification procedures for cataract extraction. The most common topical anesthetic drug used is 0.5% tetracaine eye drops. Repeated administration of 0.5% tetracaine drops can cause corneal epithelial damage. Two percent lidocaine gel is latest option which has longer contact time with corneal epithelium. Objectives: To compare the effectiveness of 2% lidocaine gel with 0.5% tetracaine drops in phacoemulsification surgery. Methods: The study was a single blinded randomized clinical trial from March to July 2017 in patients underwent phacoemulsification cataract surgery. There were 72 subjects with age ≥ 40 years old who received randomization and divided into 2 groups: 2% lidocaine gel group and 0.5% tetracaine eye drop group. Topical anesthetics were applied 5 minutes before surgery. Five minutes after surgery, pain scale perceived during surgery was assessed by using a numerical rating scale. At the end of surgery, the subject filled the satisfaction questionnaire on topical anesthetic drugs administered. The ophthalmologists were also given a satisfactory questionnaire for topical anesthetic drugs selected for the procedure. Results: The median pain scale for 2% lidocaine gel group pain scale was 1; meanwhile, the median pain scale for 0.5% tetracaine eye drops was 3 (P < 0.05). Conclusions: Two percent lidocaine gel was more effective in relieving pain during phacoemulsification cataract surgery compared with 0.5% tetracaine drops. | en |
