Ophthalmic conditions such as presbyopia, myopia, and astigmatism can be corrected by the use of a molding contact lens in combination with a pharmaceutical composition suitable for delivery to the eye. The molding contact lenses are preferably commercially available and are not specifically designed for orthokeratology. The agents in the pharmaceutical compositions such as hyaluronase allow the cornea of the eye to be molded in order to correct the refractive error of the eye. The contact lenses and the pharmaceutical composition induce a change in the radius of curvature of the anterior surface of the cornea, thereby correcting the refractive error of the eye. One advantage of the inventive technique is that the patient with his or her own individual visual needs guides the treatment until the patient near and far visual needs are met. The present invention also provides for kits, which contain molding contact lenses, pharmaceutical composition suitable for delivery to the eye, and instructions, useful in the inventive system.

Des conditions ophtalmologiques telles que la presbytie, l'hyperopie, la myopie, et l'astigmatisme peuvent être corrigées grâce à l'utilisation d'une lentille de contact de moulage en combinaison avec une composition pharmaceutique apte à une administration oculaire. Les lentilles de contact de moulage sont, de préférence, disponibles dans le commerce et ne sont pas destinées spécifiquement à l'orthokératologie. Les agents dans les compositions pharmaceutiques tels que la hyaluronase permettent la moulage de la cornée de l'oeil en vue de la correction du vice de réfraction de l'oeil. Les lentilles de contact et les compositions pharmaceutiques induisent une modification dans le rayon de courbure de la surface antérieure de la cornée, permettant ainsi la correction du vice de réfraction de l'oeil. Un avantage de la technique de l'invention est que le patient par ses propres besoins individuels visuels oriente le traitement jusqu'à la satisfaction des besoins en vision de près et de loin du patient. La présente invention a également trait à des trousses, contenant des lentilles de contact de moulage, une composition pharmaceutique apte à l'administration oculaire, et le mode d'emploi, utilisés dans le système de l'invention.
