Patent ID: 7857850

Claim:
An implantable interfacial refraction accommodating ophthalmic lens assembly which adjusts its focal distance in response to changes in the tension of the ciliary muscle of the eye of the user of said lens, the lens comprising a flexible optic chamber and cooperating haptics: the optic chamber is defined by opposed, substantially parallel visually transparent circular discs, which are flexibly coupled at their edges and spaced apart to define a closed fluidic chamber, the fluidic chamber including first and second liquids, the liquids having different refractive indices and being immiscible so as to define a spherical or lenticular interface therebetween; the haptics being coupled to the edge of the optic chamber and to the fluidic chamber so that application of force to the haptics by changes in the tension of the ciliary muscle of the eye deforms the fluidic chamber and changes the sphericity of the liquid interface; whereby the focal length of the lens changes in response to application of force to the haptics to change focus of the user.
