The purpose of this study was to compare surgical operating times and complication rates in strabismus surgery undertaken by one attending surgeon versus 10 supervised residents (most first year). Operating time was a mean of 35.5 ±6 minutes for residents compared to 19.3 ±4.8 for the attending surgeon. One major complication occurred for residents – large suture granuloma requiring excision under GA within three months of surgery. There were six minor complications for residents and one for the attending surgeon. Overall, there were 36 surgeries. The authors conclude the longer surgical times and potential complications require disclosure of resident involvement in the consenting procedure for strabismus surgery.
