Pain After Strabismus Surgery

Main hypothesis: Children ages 4-12 years will feel significantly less pain and discomfort when given regimented Tylenol every 6 hours for 48 hours after strabismus surgery (surgery to correct misaligned eyes) compared to controls whose parents are instructed to give Tylenol every 4-6 hours as needed for 48 hours after surgery. Primary Objective At Lurie Children's, the current standard practice is for patients to be prescribed oral acetaminophen as needed every 4-6 hours after strabismus surgery. However, making the acetaminophen "as needed" leaves room for error for parents to be underdosing their children and, thus, leads to increased pain felt by these pediatric patients. To date, there have been no studies comparing patient satisfaction outcomes between a group taking a course of scheduled acetaminophen every 6 hours and to a group instructed to take as needed. The investigators plan to study the differences between these two groups by using the Parent's Post-operative Pain Measure (PPPM) questionnaire to survey parents and the Faces Pain Scale-Revised to survey children at their post-operative appointment.
