Abstract

A new method for non-ablative correction of cornea shape is based on thermo-mechanical effect of laser radiation with ring-shaped laser beam. The results obtained demonstrated that the new method for correction of eye refraction yields a significant alteration in the eye refraction and the ring-shaped laser beam with various ring diameters for correction of the eye refraction allows obtaining controllable alterations of the eye refraction with axial symmetry without any pathological changes in central part of cornea.
