Methods: Sixty consecutive patients undergoing primary vitreoretinal surgery were enrolled prospectively. Results: Adequate anaesthesia and akinesia with no intraoperative supplementation was achieved in 53 eyes (88.3%). Factors influencing intraoperative supplementation were combined vitrectomy with scleral buckling (p=0.005) and duration of surgery of more than 2 hours (p=0.001). No ocular or systemic complication resulted. Conclusion: pH-adjusted periocular anaesthesia is safe and effective in patients undergoing primary vitreoretinal surgery. %0 Journal Article %I Wolters Kluwer Medknow Publications %@ 0301-4738
