    摘要: The invention relates to a device for photorefractive cornea surgery of the eye, notably laser in situ keratomileusis and photorefractive keratectomy, for the correction of higher-order visual disorders. Said device comprises the following: an aberroscope (12, 14, 16, 22, 24, 28) for measuring wavefront aberration of the complete optical system of the eye to be corrected, in relation to a defined ocular position; means (48) for deriving a photoablation profile from the measured wavefront aberrations in such a way that photoablation carried out on the basis of said photoablation profile minimizes wavefront aberration; and a laser radiation source (30) and means (32, 38, 40, 48) for controlling the laser radiation in relation to the defined ocular position, in accordance with the photoablation profile.
