Assessment of the Power and Height of Radial Aspheres Reported by a Computer-assisted Keratoscope

The two purposes of this study were (a) to assess the accuracy with which a keratoscope, the Topographic Modeling System (TMS-1). calculated the heights and powers of rotationally symmetric, radially aspheric test surfaces and (b) to determine whether the TMS-1 used an axial solution for radius of curvature to determine the power of a sphere that would produce the same semichod as would the test surface on a keratograph.
