1. A method of determining the topology of a cornea, comprising the steps of:

  • forming a first image of a natural corneal topography;

    providing a probe which is program-controlled with depth- or pressure-dependent stored data;

    indenting at least one area of the cornea by the probe to effect a momentary deformation of the anterior corneal surface;

    forming a second image of the deformation of the anterior corneal surface;

    measuring the deformation to produce commensurate topological-dependent data;

    processing and storing the data for identifying property of the cornea; and

    signaling to an operator the data for diagnostic evaluation by at least one unit selected from the group consisting of visual means and acoustic means.
