To study the associated factors with surgical success of intermittent exotropia of basic type in children. METHODS: The medical records of 58 children with intermittent exotropia treated with unilateral recession of lateral rectus muscle and resection of the medial rectus muscle and having at least 6 months of follow-up were reviewed. These surgical results were analyzed to assess the association with preoperative factors including sex, photophobia, stereopsis, vertical deviation, time of surgery and preoperative angle of deviation and early postoperative changes in motor alignment which were documented at 2 days, 1 week and 1 month after the surgery. RESULTS: There was significant difference between the early postoperative overcorrection group and others(P<0.05). The overcorrection of 10-20PD showed higher success rate than the overcorrection of 1-9PD at postoperative 1 week. Any preoperative patients' characteristics were not related to surgical outcome. CONCLUSIONS: Early postoperative overcorrection is associated with the good surgical result and the overcorrection of 10-20PD at 1 week can be the predictive factor of better surgical outcome.
