A system for performing a corneal transplantation includes a laser source for generating a laser beam and a chair for positioning a patient relative to the laser source. A stabilizing element, engageable with the laser source, is fixated on the anterior surface of the patient's cornea to hold the cornea in alignment with the laser source. The laser source is then used to remove diseased tissue from the cornea of the patient, thereby creating a corneal cavity of known dimensions. In a subsequent step, a donor graft that was previously photoaltered to have substantially the same dimensions as the corneal cavity, is transplanted into the corneal cavity.
L'invention porte sur un système d'exécution d'une transplantation de la cornée comportant: une source de faisceau laser; une chaise permettant de positionner un patient par rapport au faisceau laser; un stabilisateur en contact avec la source du faisceau et se fixant à la surface antérieure de la cornée du patient pour maintenir la cornée alignée sur le faisceau laser qu'on peut alors utiliser pour éliminer les tissus malades de la cornée. On forme ainsi une cavité cornéenne de dimensions connues dans laquelle on transplante un greffon provenant d'un donneur et photomodifié pour présenter sensiblement les mêmes dimensions.
