Publication type: Clinical Trial; Randomized Controlled Trial

PURPOSE: To assess the safety and efficacy of two topical anesthesia regimes for cataract surgery. METHODS: 21 patients received a combination of 4 times bupivacaine 0.5, oxybuprocaine and diclofenac eyedrops, 18 patients were given a single topical application of lidocaine gel 2%. A single intracameral injection of lidocaine 1% was administered to all subjects. RESULTS: The extent to which the surgeon was bothered by patient motility was graded as low in about two thirds of all procedures. Patients reported lower intraoperative pain levels with a single application of lidocaine gel supplemented with intracameral lidocaine than with a fourfold application of the combination topical anesthesia plus intracameral anesthesia. CONCLUSIONS: A single application of lidocaine gel 2% combined with intracameral anesthesia provides at least as good analgesia than multiple administration of combined topical anesthesia supplemented with intracameral anesthesia and is equally safe.
