Sub-Tenon Versus Peribulbar Anesthesia In Phacoemulsification A Comparitive Study

Purpose: The purpose is to compare the effectiveness of Sub-Tenon’s anaesthesia versus Peribulbar anaesthesia for intraoperative analgesia and ocular akinesia during phacoemulsification surgery. Material And Method: This analytic study consisted of 100 patients with simple random sampling, 50 patients in each group. Patients in group A had phacoemulsification under subtenon anaesthesia and patients in group B had the same surgery under peribulbar anaesthesia. Their eye movements and pain during surgery were documented and analyzed .Pearson Chi square test was used to determine the statistical significance. Results: In the group A (Subtenon group) there are 35 (70%) males and in group B (peribulbar group) there were 26 (52%) males. The age range of the patients was between 50-70 years. Pain during surgery in group A is 3 (24%) whereas in group B it is 28 (56%).Eye movements during the procedure of subtenon anesthesia in group A is 13 (26%) whereas eye movements during peribulbar anesthesia in group B is 22 (44%). Chi-square test is used between the eye movements and pain of group A and group B. There p values are less than 0.005 which are significant. Conclusion: Sub-Tenon anaesthesia gains our full recommendation for prospective benefits and elimination of potential fatal hazards like globe perforation, retrobulbar hemorrhage, sub arachnoid injection, imposed by using sharp needle blocks. It calms patient’s fear of sharp needles which raises the anxiety levels even prior to surgery. This technique also provides almost immediate progressive surgery.
