Background: The present study was conducted for analyzing and comparing the efficacy of Peribulbar with Posterior Sub-Tenon's Anesthesia in patients undergoing Cataract Surgery. Materials & methods:A total of 40 patients scheduled to undergo cataract surgery and more than 40 years of age were enrolled in the present study. Subjects with history of any known drug allergy were excluded from the present study. All the 40 patients were randomly divided into two study groups with 20 patients in each group as follows:Group 1: Peribulbar block group, and Group 2: Posterior sub-Tenon block. The patients underwent either manual small incision cataract surgery (MICS) or extracapsular cataract extraction with intraocular lens implantation. Pain assessment was done according to visual analogue scale (VAS). On this scale of 0 to 10, 0 indicated no pain while 10 indicated severe unbearable pain. Pain was assessment during administration of anesthesia, during surgery, and 5 minutes after surgery. Results:Mean age of the patients of group 1 and group 2 was 48.2 years and 46.1 years respectively. Non-significant results were obtained while comparing the pain among patients of the two study groups at different time intervals. Chemosis was present in 15 percent of the patients of group 1 and in 40 percent of the patients of group 2.Subconjunctival hemorrhage was present in 10 percent of the patients of group 1 and in 35 percent of the patients of group 2. Incidence of complications was significantly higher among patients of group 2. Conclusion:In terms of occurrence of complications, better results were seen among patients of Posterior sub-Tenon block group in comparison to the patients of the Peribulbar block group.
