[Intermittent exotropia : postoperative prismatic treatment]

The surgical treatment of intermittent exotropia remains a difficult problem. We present our results about our prismatic approach of the postoperative under- and overcorrections. The treatment of the overcorrections has to adapt to each case but we propose a stereotyped prismatic method (with a total amount of prismatic diopters never exceeding 5PD) to treat the undercorrections. This method is simple and well tolerated for a long term. It is especially useful in the cases of discrepancy between the far and near measurements.
