Abstract: A method of producing intra-ocular lenses or contact lenses including the following steps: a) mechanically forming a lens blank such that it is suitable for correcting an ametropic visual defect, b) measuring the aberration of an eye to be corrected, c) calculating an ablation profile with respect to the lens blank on the basis of the measured aberration, and d) ablating material of the lens blank in accordance with the calculated ablation profile by means of laser radiation.

Abstract: A device designed for generating a laser beam having a homogenized cross section has the following features:a) a pulsed solid-state laser with an emission in a wavelength range of between 2 and 3 .mu.m,b) a pulse energy of between 100 .mu.J and 1 J,c) a transmission fiber made of a material transparent to the wavelength and having a length of at least 0.2 m and a diameter of between 50 and 1000 .mu.m,d) an end piece made of quartz or sapphire and having a length of between 4 and 50 mm, the end piece following the fiber and having plane end surfaces arrange perpendicular to the longitudinal direction.
