Design outcomes

Primary

Measure	Time frame
Sample size is calculated and found to be 184, divided into two groups, 82 in each. Sensory and motor blockade onset were assessed at regular intervals, and postoperative analgesia duration was measured.Timepoint: Peribulbar block is given. Sensory block is assessed by corneal sensation at 2min intervals till loss of sensation. Motor block is evaluated at 2min interval. Postoperatively pain is assessed using the VAS every 15 min. The duration of effective analgesia is recorded from the time of block to point when VAS score reached more than or equal 3.	—
