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.
