Postoperative Subtenons Anesthesia for Postoperative Pain in Pediatric Strabismus Surgery
The purpose of this study is to determine if local anesthetic, either a subtenons injection (an injection just beneath the surface tissue of the eye) or a topical ophthalmic gel (applied directly on the surface of the eye) given at the end of strabismus surgery reduces postoperative pain. Some surgeons routinely use either the subtenon and/or topical anesthetic for pain at the end of strabismus surgery.

Primary outcomes
- Average Pain Score Over the First 30 Post-operative Minutes Using the CHEOPS Scale — 0-30 minutes post-operative
Pain will be assessed by a masked observer using the Children's Hospital Eastern Ontario Pain Scale (CHEOPS) scale. The CHEOPS (Children's Hospital of Eastern Ontario Pain Scale) is a behavioral scale for evaluating postoperative pain in young children. The scale is assessed using the sum of a score for cry (1-3), facial expression (0-2), verbalization (0-2), torso (1-2), touch (1-2) and legs (1-2). The minimum score is 4, the maximum score is 13, and higher scores indicate more pain. Pain is rated every 5 minutes for the first 30 minutes postoperatively. Each pain score collected in the first 30 minutes was averaged to calculate a per per participant average pain score over the first 30 minutes . Then each participant's per participant average pain score was combined to calculate the reported mean for "Average pain score over the first 30 post-operative minutes using the CHEOPS scale." for each group.
