An lens for correcting human vision, for example an IOL, contact lens or corneal inlay or onlay, that carries and interior phase or layer comprising a pattern of individual transparent adaptive displacement structures. In one embodiment, the displacement structures are actuated by a shape memory polymer (SMP) material or other polymer that is adjustable in shape in response to applied energy. The SMP can be designed to be selectively adjustable in volumetric dimension, modulus of elasticity and/or permeability. The adaptive optic means of the invention can be used to create highly localized surface corrections in the lens to correct higher order aberrations—which types of surfaces cannot be fabricated into and IOL and then implanted. The system of displacement structures also can provide spherical corrections in the lens.
A method of making an ophthalmic lens comprising the steps of sealably assembling anterior and posterior lens body portions about an interior phase that carries and a fixed pattern of actuatable displacement structures for deforming the lens surface to alter an optical parameter of the lens, the interior phase further comprising an index-matched fluid layer about the displacement structures, wherein the displacement structures define a scale that allows for correction of higher order aberrations.
A lens for spherical or higher order aberration correction in a human vision treatment, comprising a lens body defining an optical axis, a lens having an interior phase extending transverse to the optical axis that carries and a fixed pattern of actuatable displacement structures for deforming a lens surface to alter an optical parameter of the lens, wherein the displacement structures define a scale that allows for correcting higher order aberrations.
A method for adjusting an optical characteristic of vision correction lens, said method comprising applying energy from a remote energy source to a cooperating lens component wherein the cooperating lens component alters a parameter of a displacement element in the lens body of the lens, wherein the displacement element adjusts an optical characteristic of the lens at a plurality of locations sufficient to correct higher order aberrations.
