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 lens for spherical or higher order aberration correction in a human vision treatment, comprising a lens body defining an optical axis, first and second surfaces layers and an interior phase that extends adjacent to at least one surface layer, and a plurality of displacement structures disposed in a fixed pattern over a lateral region in the interior phase of the lens body, wherein said displacement structures are individually actuatable to alter an optical characteristic of the lens body at the location of the displacement structure, and wherein the displacement structures have a selected scale that allows for correcting higher order aberrations.
A method for adjusting an optical characteristic of vision correction lens, said method comprising selectively applying energy to a subpattern of displacement elements in a body of the lens, wherein the displacement elements respond individually to the energy to adjust the optical characteristic of lens at the locations of the subpattern of adaptive elements.
A method for correcting higher order aberrations in a vision correction lens, said method comprising the steps of:
