Evidence on effective local anesthesia for cataract surgery was lacking. The study aimed to compare the effectiveness of two common anesthetic technique used for cataract surgeries, Peribulbar Anesthesia (PBA) vs Subtenon Anesthesia (STA). Prospectively 100 subjects from a tertiary care hospital were recruited and randomly assigned to either PBA or STA group. The outcome assessed were pain during administration of anaesthesia, at the end of surgery, 4 hours after surgery, Orbital akinesia, complications and surgeons discomfort between the two groups. The results revealed a significant lesser level of pain among STA group during administration, immediately after administration and 4 hours after administration of anaesthesia than PBA group. There was no significant difference observed in the overall ocular akinesia, complication and surgeons discomfort between two groups. STA may be considered an safe and effective local anaesthesia for cataract surgery then PBA.
