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 SmallIncision Cataract Surgery
