Abstract

Procédé et dispositif de correction complète de défauts de la vision de l'oeil humain, en particulier combinaisons de procédés de mesure et de traitement qui permettent dans leur utilisation selon la présente invention la correction complète de l'oeil humain. A cet effet, on utilise des procédés de mesure qui peuvent déterminer avec précision la surface de la cornée et qui enregistrent les erreurs de représentation se produisant dans la suite de la trajectoire du faisceau jusqu'à la rétine. L'évaluation informatique de ces résultats de mesure donne la possibilité, en liaison avec le calcul de lentilles à correction idéale (par exemple après des opérations de la cataracte) ou de surfaces à correction idéales de la cornée, de fabriquer, en fonction de la topographie de l'oeil, une lentille spécifique au patient et/ou de façonner la cornée avec une correction idéale, de préférence à l'aide d'un laser excimer à balayage par points.
