Corneal curvature modification by scleral surgery: preliminary results

The preliminary results of a scleral technique designed to correct mixed and myopic compound astigmatism are given, and the mathematical basis of this technique is explained. The amount of scleral resection per diopter of astigmatism is indicated. This procedure steepens the flattest meridian and flattens the meridian localized at 90 degrees from the first one.
