Abstract:
1. An implantable interfacial refraction ophthalmic lens assembly which adjusts its focal distance in response to changing physiologic needs of a 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 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 in response to the changing physiologic need of the user to change the focal distance of the user of the lens without the need for movement of the lens assembly through its optical axis.
