Process and apparatus for changing the curvature of the cornea

摘要

A process is described for changing the curvature of the cornea in which the light of a light source is focused in the cornea with a wavelength of approximately 1.5 mu m to 6 mu m so that the collagenic tissue shrinks selectively. The invention is characterized in that the light is applied continuously at such a power that, although a temperature is reached which leads to irreversible coagulations of the collagenic tissue, the temperature within the coagulated region rises to values at which there is not yet a relaxation of the tissue.
