Paper Abstract

The constant progress in photorefractive surgery requires measurement devices with which the topography of the cornea can be measured with a high precision and bigger reproducibility than the currently used devices offer. The special two-path moire deflectometer is constructed for in vivo measurements. To overcome the problem associated with rapid eye movements, the special unit for measurement of the distance between the eye and the experimental setup, is designed. The achievable resolution of the proposed topographer is in the range of about 3 microns within a lateral measurement range of about 5 mm in diameter. The corresponding precision of the spherical equivalent dioptric number is thus better than 0.015 D.
