Abstract

A device for photorefractive cornea surgery, in particular LASIK and PRK, of the eye for the correction of sight defects of a higher order provides for the following devices:an aberroscope (12, 14, 16, 22, 24, 28) for measuring the wave-front aberration of the entire optical system of the eye to be corrected in relation to a specific eye position,means (48) for deriving a photoablation profile from the measured wave-front aberration in such a way that a photoablation in accordance with the photoablation profile minimises the wave-front aberration, anda laser radiation source (30) and means (32, 38, 40, 48) for controlling the laser radiation in relation to the specific eye position in accordance with the photoablation profile.
