Background: Today,Cataract surgery is always performed under regional or local anaesthesia, unless medically contraindicated. AIM: To compare the efficacy and safety of single injection technique of Peribulbar anesthesia with that of double site injection technique for cataract surgery. Material and Methods: This was a single-centre, hospital based, prospective observational study involving 192 patients (96 patients in each group) conducted over a period of 18 months. Patients undergoing elective cataract surgery were divided into two groups- Group S: Single site injection for peribulbar anaesthesia and Group D: Double site injection for peribulbar anaesthesia. We measured and recorded: akinesia, analgesia and complications. Results:The difference in grade of akinesia was statistically insignificant (p>0.05) between the two groups at 5-, 10-, and 15 minutes after the injection. The mean time for onset of analgesia among the participants in the single and the double injection group was 7.8 and 6.2 minutes, respectively, however, this difference was statistically insignificant (p=0.086). The mean total duration of analgesia among the participants in the single and double injection group was 103 and 118 minutes respectively, however, the difference is statistically insignificant (p=0.094). A total of 48 participants had subconjunctival hemorrhage: 19 (19.7%) in single injection group and 29 (30.2%) in double injection group (p=0.058). In the present study only 56 participants had chemosis: 23 (23.96%) in the single and 33 (34.38%) in the double injection group (p=0.112). Conclusion: When compared to double-site peribulbar anaesthesia, the single-site injection of peribulbar anaesthesia is the recommended procedure because it lowers the risk of complications.
