Summary

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.

Eligibility Criteria

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.
