Abstract
A high refractive index, foldable polymer suitable for use in ophthalmic devices, such as intraocular lenses, is provided. The polymer may be produced from a polymerization reaction of first, second and third monomeric components and a crosslinking agent. The first monomeric component includes an aryl acrylate or an aryl methacrylate. The second monomeric component, which is not an acrylate, includes a monomer having an aromatic ring with a substituent having at least one site of ethylenic unsaturation. The third monomeric component includes a high water content hydrogel-forming monomer. The resulting high refractive index copolymer is durable enough to be cut and polished when dry, and becomes soft and foldable when hydrated.
Claims3
A method of implanting an ophthalmic device within an eye, the method comprising:
- providing a hydratable ophthalmic device which is rigid at room temperature when dry and foldable at room temperature when hydrated, the hydratable ophthalmic device being hydrated, wherein the hydratable ophthalmic device comprises a copolymer including:
- a) a first monomeric component, which comprises an aryl acrylate or an aryl methacrylate;
- b) a second monomeric component, which comprises a monomer having an aromatic ring with a substituent having at least one site of ethylenic unsaturation, wherein the second monomeric component is other than an acrylate;
- and
- c) a third monomeric component, which comprises a high water content hydrogel forming monomer;
- providing a syringe containing the hydrated ophthalmic device;
- and
- injecting the ophthalmic device into the eye.
