Abstract

Official abstract text for this publication.

Fluids incorporated into intraocular lenses and their methods of use. In some embodiments the fluids are silicone oils, and in some embodiments they are used in accommodating intraocular lenses.

First claim

Opening claim text (preview).

What is claimed is: 1. An intraocular lens, comprising: a fluid chamber, and a silicone oil disposed in the fluid chamber, wherein the silicone oil is polymerized as branched polymeric structures. 2. The intraocular lens of claim 1 , wherein the silicone oil is polymerized using a living polymerization reaction. 3. The intraocular lens of claim 1 , wherein the silicone oil comprises a star-like polymeric structure. 4. The intraocular lens of claim 1 , wherein the silicone oil comprises a comb-like polymeric structure. 5. The intraocular lens of claim 1 , wherein a refractive index of the silicone oil is substantially the same as the refractive index of a bulk polymeric material of the intraocular lens, wherein the intraocular lens further comprises an optic portion, and wherein the optic portion is made in part of the bulk polymeric material, wherein the fluid chamber is within the optic portion. 6. The intraocular lens of claim 1 , wherein the intraocular lens is a fluid-driven accommodating intraocular lens. 7. The intraocular lens of claim 1 , wherein the silicone oil has a polydispersity index of less than 1.5. 8. The intraocular lens of claim 1 , wherein the silicone oil has a mean molecular weight of between 5000 Daltons and 6500 Daltons. 9. The intraocular lens of claim 1 , wherein no more than 20 wt % of the silicone oil is comprised of components below 4000 Daltons. 10. The intraocular lens of claim 1 , wherein no more than 10 wt % of the silicone oil is comprised of components below 3000 Daltons. 11. An intraocular lens, comprising: a fluid chamber, and a silicone oil disposed in the fluid chamber, wherein the silicone oil is polymerized as branched polymeric structures, and wherein the branched polymeric structures comprise an X-shaped polymeric structure. 12. An intraocular lens, comprising: a fluid chamber, and a silicone oil disposed in the fluid chamber, wherein the silicone oil is polymerized as branched polymeric structures, and wherein the intraocular lens is a non-accommodating intraocular lens.
