Abstract

Background: Cataract extraction was commonly carried out using Retrobulbar anaesthesia. Use of this technique is rarely associated with  serious complications like retrobulbar hemorrhage, globe perforation, optic nerve injury.Due to these complications many ophthalmologists replaced retrobulbar anaesthesia with peribulbar anaesthesia. However peribulbar anaesthesia does not prevent serious complications totally, although these probably      occur less frequently. Even with a two injection technique, it has sometimes an excessive rate of imperfect blockade and pain. Subtenon anaesthesia provides a quicker onset of anaesthesia, better akinesia and more consistency in effectiveness and better patient compliance. Objectives:To compare the safety and efficacy of subtenon’s anaesthesia and peribulbar anaesthesia in Manual Small Incision Cataract Surgery.Methodology: Study was carried out during the period from January 2018 to July 2019.The study was conducted on 100 randomly selected patients fulfilling the criteria .The study was conducted at Mediciti Institute Of Medical Sciences, Ghanpur Telangana,India. Results: Intra operative pain was dramatically lower in subtenon group of patients with significantly fewer patients experiencing unacceptable levels of pain. Subtenon group of patients had good analgesia but surgeons had to operate under incomplete akinesia. Peribulbar anaesthesia had an upper hand in terms of intra operative akinesia when compared with subtenon anaesthesia Intra operative lid movements were slightly more in subtenon group of patients. The incidence of chemosis was almost comparable in both the groups. Subconjunctival haemorrhage was more in subtenon group as compared with patients in peribulbar group Conclusion: From the results it can be concluded that that subtenon form of anaesthesia is as safe as peribulbar anaesthesia, giving good analgesia during surgery.
