title: A spline surface algorithm for reconstruction of corneal topography from a videokeratographic reflection pattern.
abstract: A videokeratograph quantifies one or more aspects of corneal shape by the computer analysis of a digital image. The image is the reflection formed by illuminating the cornea with a known source pattern. The type of shape information recovered and the accuracy of this information depend upon properties of the computer algorithm used in the analysis. We present a new algorithm that recovers a polynomial spline description of corneal depth.
