Paper Abstract

We describe a new multipurpose maskless method of corneal surgery based on the point-by-point scanning of a focused laser beam which allows the application of a low-energy excimer laser. The crucial scanning parameters to achieve a smooth corneal surface have been investigated. A computer program for the simulation and optimization of the point-by-point scanning process has been developed and tested on contact lenses consisting of PMMA. In addition, a method of measuring the eye-movement by means of the computer-assisted interpretation of photographs was proved for its application in an eye-tracking-system.
