Title (EN) INTRAOCULAR PROSTHESES
(FR) PROTHESES INTRAOCULAIRES
Abstract:
(EN) An intraocular prosthesis (56) for implanting in an annular void extending radially into the tissues of the eye. The prosthesis is a circular, transparent, elastomeric optical element (57) having a peripheral edge and a non-rigid or flexible porous skirt (68) which extends radially from the periphery of the element. The skirt encircles the element and is positioned to extend radially into the void. An annular, flexible porous portion (68) having a pore size in the range of about 25-90 microns, and preferably about 60 microns, is included with the skirt. The porous portion surrounds the elements and is disposed in contact with the tissues of the eye surrounding the void to allow fibrous growth into the pores of the porous portion. A plurality, preferably six, spoke-like, porous extensions (54) may be included.
(FR) Prothèse intraoculaire (56) destinée à être implantée dans un vide annulaire s'étendant radialement dans les tissus de l'oeil. La prothèse est un élément (57) circulaire, tansparent, élastomère, optique, ayant un bord périphérique et une jupe (68) poreuse non rigide ou souple s'étendant radialement à partir de la périphérie de l'élément. La jupe encercle l'élément et est positionnée pour s'étendre radialement dans le vide. Ue partie (68) annulaire, flexible, poreuse, ayant la taille d'un pore situé dans la plage allant d'environ 25 à 90 microns, et de préférence d'environ 60 microns, est comprise avec la jupe. La partie poreuse entoure l'élément et est disposée en contact avec les tissus de l'oeil entourant le vide, pour permettre la croissance fibreuse dans les pores de la partie poreuse. Une pluralité, de préférence six, d'extensions (54) poreuses en forme de rayon peut être comprise.
