Adaptive optic lens and method of making
A 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. An intraocular lens, comprising:
an optic portion in fluid communication with a non-optic portion, and a first region of shape change polymers and a second region of shape change polymers, the first and second region of shape change polymers disposed in the non-optic portion, each of the first and second region of shape change polymers are adapted to change configuration in response to the application of heat from an external energy source disposed outside of the eye when the intraocular lens is positioned in an eye, wherein the optic portion comprises an anterior body layer, the anterior body layer being the anterior-most portion of the optic portion and a posterior body layer being the posterior-most portion of the optic portion, and
wherein the change in configuration of any of the first region of shape change polymers causes a fluid to move from the optic portion to the non-optic portion, and wherein a change in configuration of any of the second region of shape change polymers causes the fluid to move from the non-optic portion to the optic portion.
2. The intraocular lens of claim 1 wherein the first and second region of shape change polymers are adapted to change configuration in response to the application of light energy from an external light energy source.
3. The intraocular lens of claim 1 wherein movement of the fluid causes a change in configuration of the anterior body layer.
4. The intraocular lens of claim 1 wherein the anterior body layer and the posterior body layer are sealed with a polymer precursor that has been polymerized.
