Abstract
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.
