The disclosure relates generally to a polymeric material for use in accommodating intraocular lenses for implantation in a lens chamber of a subject's eye. The present disclosure is directed to a polymeric material which comprises a fluorosilicone polymer and a silica component. The presently disclosed polymeric material is both optically clear and has a sufficiently low Young's modulus such that it can effectively respond to the eye's natural accommodative forces and thus can be used in accommodating intraocular lenses. When used in the fabrication of an intraocular lenses, the polymeric material disclosed herein protect the physical characteristics of the lens as the added hydrophobicity of the fluorosilicone polymer allows it to effectively resist diffusion of fluid from the eye and the adhesion of biologica materials.
