CA 2162394

The present invention provides semi-spherical materials to be worn on the eyeball, such as contact lenses for visual acuity correction or medical treatment use, cornea protecting materials, controlled drug release contact lenses and the like, which comprise, as a main component, a existing in the living body as an extracellular matrix component of connective tissues and satisfy various requirements such as a dimensional stability, transparency, surface water wettability, tissue compatibility, oxygen permeability and the like. In other words, the material to be worn on the eyeball has a shape of semi-spherical surface compatible in shape with the mammalian eyeball and has biological and surface-physical compatibilities with ophthalmic tissues and comprises, as a main component, a substantially transparent photocured crosslinked-glycosaminoglycan obtained by allowing photoreactive groups covalently bonded to a glycosaminoglycan to crosslink mutually by photoirradiation.

La présente invention concerne des matériels hémisphériques à porter sur le globe oculaire tels que notamment des lentilles de contact correctrices ou pour traitement médical, des protections cornéennes, des lentilles de contact pour administration médicamenteuse contrôlée. Leur principal composant, un glycosaminoglycan déjà présent dans un corps vivant sous forme de matrice extra-cellulaire dans les tissus conjonctifs, est conforme à diverses spécifications concernant notamment la stabilité dimensionnelle, la transparence, la mouillabilité de surface par l'eau, la compatibilité tissulaire, et la perméabilité à l'oxygène. Ces matériels à porter sur le globe oculaire ont donc une surface de forme hémisphérique compatible avec la forme du globe oculaire des mammifères. Ces matériels dont la physique de surface présente des caractéristiques de compatibilité avec les tissus ophtalmiques, sont principalement constitués d'un glycosaminoglycan réticulé photodurci essentiellement transparent que l'on obtient en permettant la réticulation réciproque par photo-irradiation de groupes photoréactifs à liaisons covalentes avec un glycosaminoglycan.
