摘要:
Methods of adjusting an intraocular lens after implantation. In some embodiments the methods include positioning an accommodating intraocular lens within an eye, the intraocular lens comprising an optic portion in fluid communication with a peripheral chamber, wherein movement of a fluid between the peripheral chamber and the optic portion in response to ciliary muscle movement changes the optical power of the lens, and reducing a power of the intraocular lens by causing the fluid to move between the optic portion and the peripheral chamber, wherein the reduction in power of the intraocular lens is not in response to ciliary muscle movement, and wherein the positioning step occurs prior to reducing the power.

摘要:
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.

Accommodating intraocular lenses and methods of use which account for changes to a capsular bag post-implantation as well as a mismatch is size between the accommodating intraocular lens and capsule.
摘要:
An accommodating intraocular lens is provided having optical parameters that are altered in-situ, wherein an optic portion of the lens includes a lens piston that alters the shape of a lens element of the lens to alter the optical power of the lens, responsive to forces applied to a haptic portion to the lens by contraction of the ciliary muscles. 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.

摘要:
An accommodating intraocular lens is provided having optical parameters that are altered in-situ, wherein an 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 a haptic portion to 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. Displacement of fluid to the actuator may either increase or reduce the degree of deflection imposed on the lens element by the actuator.
