Postoperative Subtenons Anesthesia for Postoperative Pain in Pediatric Strabismus Surgery

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.

Inclusion Criteria:

• Age 1 year to < 8 years
• Undergoing strabismus surgery under general anesthesia
• No previous surgery on muscle to be operated
• No known allergy to lidocaine or bupivacaine
• Investigator willing to inject subtenons NS or preservative-free bupivacaine 0.75% by cannula into all surgical wounds and willing to administer topical lidocaine 3.5% ophthalmic gel or Hypromellose 0.3% gel (GenTeal Severe Dry Eye Relief) to all surgical wounds at the end of strabismus surgery.
