Abstract: 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.

Abstract: Biocompatible polymers useful in ophthalmic devices such as accommodating intraocular lenses. The polymers have improved resistance to the diffusion of fluid, relatively high refractive indexes, and mechanical properties to allow for deformation upon the application of force.

Abstract: Fluid-driven accommodating intraocular lenses comprising deformable optic portions.

Abstract: An accommodating intraocular lens includes an optic portion a haptic portion and a backstop. The optic portion of the lens includes an actuator that deflects a lens element to alter the optical power of the lens responsive to forces applied to the haptic portion of the lens by contraction of the ciliary muscles. Forces applied to the haptic portion may result in fluid displacements from or to the haptic portion from the actuator. The backstop provides support to the haptic so that bulk translation of the haptic is prevented in response to the forces applied by the capsular sac.

Abstract: A deformable intracapsular implant device for shaping an enucleated lens capsule sac for use in cataract procedures and refractive lensectomy procedures. In one embodiment, the intraocular implant devices rely on thin film shape memory alloys and combine with the post-phaco capsular sac to provide a biomimetic complex that can mimic the energy-absorbing and energy-releasing characteristics of a young accommodative lens capsule. In another embodiment, the capsular shaping body is combined with an adaptive optic. The peripheral capsular shaping body carries at least one fluid-filled interior chamber that communicates with a space in a adaptive optic portion that has a deformable lens surface. The flexing of the peripheral shaping body in response to zonular tensioning and de-tensioning provides an inventive adaptive optics mechanism wherein fluid media flows between the respective chambers “adapts” the optic to increase and decrease the power thereof.

Abstract: An accommodating intraocular lens is provided in which a deflectable lens element is anchored to a substrate along its optical axis to define a fluid filled space. Fluid-filled haptics disposed in fluid communication with the space vary the fluid volume in the space responsive to forces applied by the ciliary muscles, thereby causing the periphery of the lens element to deflect relative to the substrate and changing the optical power of the intraocular lens.

Abstract: An intraocular lens (IOL) that provides for optical power adjustment following its implantation, for example, for use in treating cataract patients. The lens body has first and second surface portions that bound at least one interior chamber or space that extends from the central optic portion to the lens periphery. The interior chamber or space has a microporous body that is intermediate inner and outer portions of the space. In one embodiment, the microporous body is capable of cooperating with an external Rf or light source to expose a charge to a charge-carrying fluid within the interior chamber. By this system, fluid flows are induced to alter the optical parameters of the lens.

Abstract: An accommodating intraocular lens includes an optic portion, a haptic portion. The optic portion of the lens includes an actuator that deflects a lens element to alter the optical power of the lens responsive to forces applied to the haptic portion of the lens by contraction of the ciliary muscles and a secondary deflection mechanism. Movement of the lens element by the actuator causes the lens element to deform and the secondary deflection mechanism causes the lens to further deform.

Abstract: An accommodating intraocular lens is provided, in which optical parameters are altered in-situ using forces applied by the ciliary muscles, and in which a lens body carries an actuator separating two fluid-filled chambers having either the same index of diffraction or different indices of refraction. The actuator causes the relative volumes of fluid within an optic element of the lens to change, thereby altering the optical power of the lens.

Abstract: An intraocular lens is provided that having optical parameters that may be adjusted in-situ, and is particularly useful in cataract patients that require an adjustment in the optical power of the lens post-implantation. The lens body carries an array of interior fluid-filled cells in which fluid is controllably moved by micropumps upon application of energy from an external source to move a fluid media into the cells to thereby alter the lens surface shape.

Abstract: 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.

Forces applied to the haptic portion are concentrated by the lens piston to provide a greater dynamic range, and may be further augmented by the use of haptic pistons disposed in the haptic portion of the lens.
