Abstract

Trephination was performed for the purpose of correction of undercorrection after epikeratoplasty. We classified two group-Delayed regression group represented regression toward myopia more than 3D again after spherical equivalant become stable. Undercorrection group represented remained myopia after epikeratoplasty. Thirteen trephinations were performed on eleven eyes. Mean follow-up period was 22.4 weeks. In skiascopy, totally 1.15D myopia was decreased. In delayed regression group myopia was increased 0.5D, while in undercorrection group, myopia was dereased 3.5D, The results of three eyes in eleven eyse were satisfactory. Those 3 cases were from undercorrection group. The results suggest that trephination might be effective method for correction of remained myopia in undercorrection group.
