Adaptive optic lens and method of making
View Patent ↗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 the exemplary embodiments, the displacement structures are actuated by shape change polymer that adjusts a shape or other parameter in response to applied energy that in turn displaces a fluid media within the lens that actuates a flexible lens surface. 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.
1. A lens for vision correction comprising a lens body defining a peripheral non-optic portion and a central optic portion having an optical axis, the peripheral non-optic portion including a shape memory polymer (SMP) and the central optic portion excluding a SMP.
2. A lens as in claim 1 wherein the SMP has a memory shape and is self-maintainable in a different temporary shape, and wherein the SMP is moveable from the temporary shape toward the memory shape in response to a stimulus.
3. A lens as in claim 2 wherein the stimulus is heat.
4. A lens as in claim 2 wherein the SMP includes a chromophore for cooperating with a selected light wavelength.
5. A lens as in claim 4 wherein the stimulus is energy from irradiation by the selected light wavelength.
