Abstract

Procédé et appareil permettant à un système d'alignement sur l'oeil d'obtenir un pointage plus précis, comprenant un laser de superposition exacte ou un laser de pointage permettant de localiser avec précision le point de l'oeil que doit frapper le prochain tir d'ablation par laser. Ce procédé et cet appareil impliquent en outre l'utilisation d'un dispositif d'aide au pointage, constitué d'un cadre fixe de référence destiné à localiser la naissance de l'oeil.
