High refractive index copolymers with reduced tack are disclosed. The copolymers, which are particularly suitable for use as ophthalmic device materials, comprise a benzhydryl methacrylate or benzhydryl methacrylate derivative monomer.

High refractive index ophthalmic device materials with reduced tack

Disclosed are soft, high refractive index, acrylic materials. These materials, especially useful as intraocular lens materials, contain one or more aryl acrylic hydrophobic monomers as principal device-forming monomers and a tack-reducing macromer additive. 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.

Low-tack ophthalmic and otorhinolaryngological device materials

High refractive index copolymers suitable for use in ophthalmic devices are disclosed. The copolymers comprise a single aryl hydrophobic monomer as a device forming monomer. In addition, the copolymers comprise a non-polymerizable block copolymer surfactant. The copolymers have a reduced tendency to form glistenings when stored in water at physiological temperatures.
