Disclosed are soft, high refractive index, acrylic materials having an elongation of at least 150 %. These materials, especially useful as intraocular lens materials, contain an aryl acrylic hydrophobic monomer as the single principal device-forming monomer. In addition to their use as intraocular lens materials, the present materials are also suitable for use in other ophthalmic or otorhinolaryngological devices, such as contact lenses, keratoprostheses, corneal inlays or rings; otological ventilation tubes and nasal implants.
L'invention concerne des matériaux acryliques souples à indice de réfraction élevé présentant un allongement d'au moins 150 %. Ces matériaux, particulièrement utiles comme matériaux de lentilles intraoculaires, contiennent un monomère acrylique aryle hydrophobe comme unique et principal composant. Ces matériaux peuvent être utilisés, mis à part leur utilisation comme matériaux de lentilles intraoculaires, dans d'autres dispositifs ophtalmiques ou oto-rhino-laryngologiques comme des verres de contact, des kératoprothèses, des incrustations ou des anneaux cornéens, des tubes de ventilation otologiques et des implants nasaux.
