Un Israélien de 78 ans, aveugle, a retrouvé la vue après une greffe de cornée artificielle. C’est la première fois qu’une telle intervention réussit.
Jamal Furani de Haïfa a pu lire un texte et reconnaître des proches après avoir reçu l’implant biomimétique de “CorNeat Vision” au cours d’une opération qui a duré moins d’une heure le mois dernier.
“Voir un autre être humain retrouver la vue était électrisant et émouvant” a déclaré le co-fondateur de la société, le docteur Gilad Litvin. «Il y avait beaucoup de larmes dans la pièce.»
La cornée artificielle, constituée d’un matériau poreux synthétique s’insère dans la paroi oculaire pour remplacer les cornées cicatrisées ou déformées.
Une fois implanté, le matériau s’intègre aux tissus vivants en stimulant la «prolifération cellulaire» dans l’œil, en partie grâce au génie chimique à l’échelle nanométrique, a déclaré la société.
Une fois ses bandages retirés, le patient a vu la lumière. “La procédure chirurgicale était simple et le résultat a dépassé toutes nos attentes”, a déclaré le professeur Irit Bahar, qui a pratiqué la chirurgie implantaire.
L’homme avait souffert d’un œdème de l’œil qui l’avait rendu aveugle pendant environ une décennie. Il était l’un des 10 patients sélectionnés pour la procédure expérimentale au Rabin Medical Center, deux autres sites devant ouvrir au Canada ce mois-ci.
D’autres sites aux États-Unis, en France et aux Pays-Bas sont en attente d’approbation.
