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.
L'invention concerne un système s'utilisant en chirurgie photoréfractive de la cornée, notamment de type LASIK (Laser in situ Keratomileusis = kératomileusis in situ au laser) et PRK (photorefraktive Keratektomie = kératectomie photoréfractive), pratiquée sur l'oeil, afin de corriger des troubles de la vision d'ordre supérieur. Ce système comprend les dispositifs suivants : un aberroscope (12, 14, 16, 22, 24, 28) pour mesurer l'aberration de front d'onde de l'ensemble du système optique de l'oeil à corriger par rapport à une position déterminée de l'oeil ; des moyens (48) pour dériver un profil de photoablation de l'aberration de front d'onde mesurée, de manière qu'une photoablation minimise l'aberration de front d'onde selon le profil de photoablation, et une source de rayonnement laser (30) et des moyens (32, 38, 40, 48) pour piloter les rayonnements laser par rapport à la position déterminée de l'oeil en fonction du profil de photoablation.
