Sub Tenons Block vs Peribulbar Block: A Comparative Study of Pain, Efficacy and Safety in Small Incision Cataract Surgery
Abstract: Background: This study compared sub-Tenon's block and peribulbar block in patients undergoing bilateral small incision cataract surgery, focusing on pain, efficacy, safety, and surgeon comfort. Methods: A prospective randomised interventional study included 57 patients with bilateral immature cataracts undergoing sequential bilateral small incision cataract surgery. Each patient received sub-Tenon?s block in one eye and peribulbar block in the other, in randomized order. Pain, block onset, efficacy, complications, and surgeon comfort were assessed. Results: Sub-Tenon's block caused significantly less pain during administration compared with peribulbar block (p less than 0.001). Intraoperative pain was comparable between groups. Sub-Tenon's block had significantly faster onset (72.89 vs 168.37 seconds, p less than 0.001). Block efficacy and surgeon comfort were comparable. Retrobulbar haemorrhage occurred only in the peribulbar group (10.5%). Conclusion: Sub-Tenon's block appears to be a safer and more comfortable alternative to peribulbar block, with faster onset and comparable surgical efficacy in small incision cataract surgery.
