Reconstruction of the corneal shape with the MasterVue Corneal Topography System

This paper explains how the Humphrey MasterVue Corneal Topography System measures the corneal shape and explains what is meant by the various values presented. Covered are the geometrical concepts underlying the method, the necessary reconstruction steps, a description of the arc step reconstruction method used, a description of the cone of focus concept, and definitions of the presented power values.
