“COMPARISON OF PERIBULBAR ANESTHESIA WITH POSTERIOR SUBTENON'S ANESTHESIA IN MANUAL SMALL INCISION CATARACT SURGERY (MSICS)”

Abstract

Background: Cataract-related blindness is a huge problem in India, not only in terms of human suffering but also in terms of economic loss and social impact. For cataract extraction, retrobulbar anaesthesia was widely employed. Because of its substantial difculties, retrobulbar anaesthesia was replaced with peribulbar. Despite a two injection method Peribulbar anaesthesia has a very high failure rate. Subtenon's anaesthesia is becoming more popular in this situation, Because of its faster onset in delivering anesthesia, akinesia and patient compliance. A cross- Methods: sectional study in ophthalmology department at Sri Siddhartha Medical College, Tumkur was conducted over a period of 18 months in 150 MSICS participants , with 75 participants in each group. The efcacy and safety of two types of anaesthesia in MSICS were compared in terms of intraoperative analgesia, akinesia, lid movements, and complications. Out of Results: 75 participants in each group percentage with grade 0 pain in posterior subtenon's group was 64(83 %) as compared to 6( 8%) in peribulbar group. Among all 20 (27%) participants of peribulbar group and 2 (3%) of posterior subtenon's group had attained complete akinesia. Both the groups had experienced similar amount of lid movements. Occurrence of complications like chemosis and sub conjunctival hemorrhage was noted more in posterior subtenon's group when compared to peribulbar group
