Every year over 1,000 children undergo eye muscle surgery provided by physicians at this institution. For many of these children this is not and will not be the only surgical procedure for eye muscle correction. All of these children will experience differing degrees of postoperative pain. The pain associated with strabismus surgery is due to the manipulation in the conjunctival area and further handling of Tenon's capsule, sclera and the stretching of the eye muscle . Research has demonstrated that repeated painful procedures result in increased anxiety and increased pain.
