Corneal curvature changes after retinal reattachment surgery. We investigated corneal curvature changes after episcleral buckling procedure. Circumferential buckling (22 eyes) induced steepened corneal curvature steep close to the direction of the buckling. Radial buckling (15 eyes) induced flattening of the corneal curvature in the direction of the buckling. These changes, however, disappeared within two months after the surgical procedure. Encircling buckling (15 eyes) induced heightening of the cornea curvature in all cases steeper, and this finding was observed even three months after the procedure. There was no significant difference in axial length before and after the operation. These results indicated that the refractive power changes were due to the corneal curvature changes, but not elongation of axial length changes.
