  • Patent number: 10751167
    Abstract: An intraocular lens focuser (114) to be implanted in a human eye includes a resiliently deformable force applicator (140) to apply a focussing force to an accommodating intraocular lens and an attaching portion configured to enable attachment of the lens focuser in the eye. The force applicator is configured such that, in use, when a ciliary muscle of the eye is relaxed to place the accommodating intraocular lens in a distance vision condition, the force applicator is in a deformed condition and when the ciliary muscle contracts to place the accommodating intraocular lens in a near vision condition the force applicator resiles towards a relaxed non-deformed condition to at least assist in placing the accommodating intraocular lens in the near vision condition.

  • Patent number: 8998984
    Abstract: An adjustable astigmatism-reducing intraocular lens includes a toric optic with a long axis. The optic is rotationally coupled to haptics, and a plurality of struts extend between the optic and the haptics. The struts are held under tension and individually releasable via laser, or are heat shrinkable to increase the tension of selective struts. When a strut is released or shrunk, a torsional force is applied to angularly adjust the optic relative to the haptics. After the lens has been implanted and healed relative to the tissue, struts are individually released via laser ablation to cause torsional instability and resulting net rotational adjustment, or individually heat shrunk to tension the strut, to cause torsional instability, and effect net rotational adjustment to ensure that a long axis of optic is aligned with the axis of astigmatic correction of the eye.

  • Publication number: 20120016473
    Abstract: An intraocular lens for implantation in a capsular bag of an eye includes an optic disposed about an optical axis and a haptic including a protruding portion disposed inside the optic. The optic has an anterior face and an opposing posterior face that are configured to provide a lens power. In response to an ocular force of the eye, the haptic transmits a force that alters one or more of a shape of the optic and an axial thickness of the optic. The protruding portion of the haptic has a refractive index that is equal to a refraction index of the optic for at least one a wavelength within the visible spectrum.

  • Patent number: 8034108
    Abstract: An intraocular lens is disclosed, with an adjustable optic that changes shape in response to a deforming force exerted by the zonules of the eye. A haptic supports the optic around its equator and couples the optic to the capsular bag of the eye. The haptic may include a cap on the anterior and/or posterior surfaces of the lens. The lens may include a force transfer member, such as a hinge, that couples forces from the haptic to the cap, so that a radial force on the haptic changes the curvature of the cap. The haptic and optic may be refractive index-matched. The cap may be made of the haptic material, which is stiffer than the optic material, and can influence the deformation of the lens during accommodation. A cap on the anterior surface may produce an axial movement of the lens in an anterior direction during accommodation. The cap may also protect the surfaces of the optic during handling and installation.

  • Publication number: 20110238174
    Abstract: An accommodating intraocular lens (AIOL) includes an optic adapted to produce a trapezoidal phase shift and a plurality of haptics. Each haptic extends from a haptic-optic junction to at least one transverse arm contacting a capsular bag of the eye, and each haptic has sufficient length and rigidity to stretch a capsular bag of the eye to contact ciliary muscles of the eye. The haptic-optic junctions vault the optic forward relative to the haptics and compression of the haptics by the ciliary muscles moves the anterior optic forward. A combined accommodative power produced by the motion of the anterior optic and the trapezoidal phase shift is at least 0.5 Diopters.

  • Patent number: 7713299
    Abstract: An intraocular lens is disclosed, with an optic that changes shape in response to a deforming force exerted by the zonules of the eye. A haptic supports the optic around its equator and couples the optic to the capsular bag of the eye. The region of contact between the optic and the haptic extends into the edge of the optic, similar to the interface between a bicycle tire and the rim that holds it in place. The haptic may be stiffer than the optic. The haptic may have the same refractive index as the optic. The haptic may include a saddle-shaped portion in contact with the adjustable optic, with a convex profile along an optical axis; and a concave profile in a plane perpendicular to the optical axis.

  • Publication number: 20090292356
    Abstract: An improved multifocal design for IOL is provided. A particular embodiment includes an intraocular lens (IOL) with a foldable optic. The IOL also includes multi-hinged haptics coupled to the foldable optic operable to position the IOL within an eye. Each of the multi-hinged haptics includes a first hinge and a second hinge farther from the foldable optic. The first hinge has a first thickness between an anterior side and a posterior side of the multi-hinged haptic, the second hinge has a second thickness between the anterior side and the posterior side of the multi-hinged haptic, and the first thickness is greater than the second thickness. Another embodiment of the present invention provides a method to correct the visual impairment of an aphakic patient by implanting such an IOL.
