Ophthalmic lenses, such as corneal contact lenses, include a lens body made of a composition including a lens body made of a composition including a first crosslinked polymer material which is water swellable, and a second polymeric material, other than the first material, selected from water soluble polymeric materials, water swellable polymeric materials and mixtures thereof. The second material is physically immobilized by the first material. Such lenses provide increased water retention and/or increased water content and/or increased modulus and/or reduced friction which increases lens wearer comfort. Compositions and methods for providing such lenses and compositions are also provided.

Ophthalmic lenses and compositions, and methods for producing same

Compositions and methods for treating a contact lens are disclosed. In one embodiment, the composition comprises an ophthalmically acceptable liquid aqueous medium and a plurality of particles which possess a hardness gradient. The hardness gradient of the particles is due to the particles having a relatively inelastic, water-impermeable core and a soft, water-permeable outer layer surrounding the core. The particles afford both high specific pressure on a contact lens surface and textural softness, which diminishes surface abrasion.

Contact lens cleaning compositions with particles of variable hardness

Compositions and methods for destroying hydrogen peroxide in hydrogen peroxide-containing liquid aqueous media, for example, employed to disinfect contact lenses, are disclosed. In one embodiment, the present composition comprise at least one item containing a hydrophilic polyurethane component and a catalase component covalently bonded to the hydrophilic polyurethane component.

Method for disinfecting contact lens with catalase compositions

A water swellable crosslinked polymer of essentially balanced charge is obtained by polymerizing a polymer-forming composition comprising a cationic-anionic pair of ethylenically unsaturated monomers and a non-ionic ethylenically unsaturated hydrophilic and/or hydrophobic monomer. Contact lenses formed from the polymer exhibit little if any tendency to attract soils, e.g., proteinaceous debris, to their surfaces.
