Purpose: Topical and intracameral anaesthesia in cataract surgery are gaining in importance and popularity .
Method: We conducted a prospective, double-blind, randomized, one-surgeon trial which included 48 eyes of 38 consecutive patients who underwent clear corneal phacoemulsification surgery. 27 eyes were given a single application of lidocaine gel 2 %, 19 eyes received four times bupivacaine 0.5 % drops, diclofenac drops and oxybuprocaine 1 % drops before surgery. During surgery all patients were given a single intracameral lidocaine 2 % injection . The surgeon graded patient cooperation and intraoperative pain level using a 0 to 10 visual analog scale. Duration of surgery and intraoperative complications were recorded. Patients were asked to grade their intraoperative pain levels based on a 0 to 10 visual analog scale and to document postoperative pain levels, need for pain medication and satisfaction with topical anaesthesia compared to retrobulbar anaesthesia if already experienced.
Results: With single application of lidocaine gel in combination with intracameral lidocaine injection or fourfold application of bupivacaine drops and intracameral lidocaine low and similar intraoperative pain levels were found (0.75 ± 0.40 resp. 0.47 ± 0.33). Patient cooperation was very good in 17 of 27 eyes in t
