  • Publication number: 20140107777
    Abstract: An implantable ophthalmic device connectable to an implantable accommodating lens includes a dual-chamber sensor cell having a first and second plate where the second plate is disposed opposite the first plate. A first chamber with a first flexible membrane is disposed on an inner side of the first plate. A second chamber with a second flexible membrane is disposed on an inner side of the second plate. A space resides between the first and second chambers configured to receive a scleral spur of a ciliary muscle of a patient's eye. A connecting element is attached at a first end to the dual-chamber sensor cell. The connecting element includes a first and second channel disposed along a length of the connecting element and in communication with the first and second chamber of the dual-chamber sensor cell, respectively. The second end of the connecting element is connectable to the implantable accommodating lens.

  • Publication number: 20140100654
    Abstract: An ophthalmic multifocal switchable lens includes a deformable element manifesting elevated strain with a formable surface of a multifocal surface shape to provide far and near vision. A transparent chamber is filled with optical matching fluid adjacent to the side of the deformable element opposite to the formable surface. The optical matching fluid has a refractive index that matches a refractive index of the deformable element material. A holding chamber is also filled with the optical matching fluid and connected with the transparent chamber with a means for preventing the optical fluid from being transported from the holding chamber to the transparent chamber which would reduce a strain of the deformable element. A split of light between far and near vision of the multifocal switchable lent changes upon a removal of the means to allow a flow of the optical matching fluid into the transparent chamber.

  • Publication number: 20140085726
    Abstract: A lens in accordance with the present invention includes an switchable cell consisting of optical substrate with diffraction surface, elastic film in contact with the diffraction surface of the substrate, optical fluid that fills the space between the film and diffraction surface and the mean to transfer the optical fluid in and out of the space between the film and diffraction surface. The refractive index of the optical fluid matches the refractive index of the optical substrate. The switchable cell changes focus positions between refractive focus in relaxed state when the pressure at both sides of the film is the same and diffraction focus when the optical fluid is transported from the space between the film and optical substrate for the film to largely conform to the diffraction surface shape of the optical substrate.

  • Patent number: 8668333
    Abstract: An ophthalmic toric lens to be worn on an eye or implanted inside of an eye, the lens includes an anterior surface, a posterior surface, and a toric shape formed into one of the anterior and posterior surfaces, the toric shape comprising two non-spherical principle meridians each having a region within an annular area of optical zone and the region of one principle meridian being configured for producing a longitudinal ray aberration of a different sign than a longitudinal ray aberration sign from the region of another principle meridian.

  • Patent number: 8608800
    Abstract: A lens in accordance with the present invention includes an accommodating cell having two chambers with at least one chamber filled with optical fluid with the refractive index matching the refractive index of the accommodating element separating them. The accommodating element has a diffractive surface with surface relief structure that maintains its period but changes its height due a pressure difference between the chambers to redirect most of light that passes through the lens between different foci of far and near vision. The invention also includes a sensor cell that directly interacts with the ciliary muscle contraction and relaxation to create changes in pressure between the accommodating cell chambers that results in changing surface relief structure height and the lens accommodation.

  • Patent number: 8579970
    Abstract: A telescopic intraocular lens system comprises a telescopic optical system comprising an anterior optic interconnected with a posterior optic. The optics are substantially aligned on an optical axis of the optical system. The optics are formed from a soft material and the optics are substantially immovable relative to each other along the optical axis in response to accommodative forces of the type observed in the capsular bag of the human eye.

  • Patent number: 8287593
    Abstract: An adjustable multifocal intraocular lens system for an individual's eye, includes a base multifocal intraocular lens having an optic with an optical axis, a peripheral edge, a multifocal optical power anterior surface and a posterior surface along with an attachment for maintaining the base multifocal lens in the individual's eye with the optical axis centered along an eye optical axis. An enhanced multifocal intraocular lens is provided with an optic with a peripheral edge, an anterior surface and a reverse multifocal optical power posterior surface, and a coupling enables assembly of the base lens and enhance lens with the enhance lens posterior surface overlaying the base lens anterior surface in order that the enhance intraocular lens reverse multifocal surface adjust multifocal powers of the base IOL by substantially masking near power of the base multifocal intraocular lens.

  • Patent number: 8062361
    Abstract: An accommodating intraocular lens implantable in an eye. The lens comprises an anterior portion having an anterior biasing element and an anterior optic having refractive power. The lens further comprises a posterior portion having a posterior biasing element and a posterior optic having refractive power. The anterior optic and the posterior optic are relatively moveable in response to action of the ciliary muscle to change the separation between the optics and the refractive power of the lens. The lens has an aberration-inducing force characteristic of about 70 mg to about 115 mg to allow aberration-inducing relative movement of the optics when the lens is in the eye, thereby adding optical aberration to the lens which increases depth of focus of the lens. In one variation, the lens has an aberration-inducing force characteristic of 70 mg to 115 mg. Related methods are also disclosed.

  • Publication number: 20110060409
    Abstract: An intraocular lens implantable in an eye includes an optic for placement in the capsular bag of the eye and for directing light toward the eye's retina. The optic has a central optical axis, an anterior surface, an opposing posterior surface and optic peripheral edge surface between the surfaces. The peripheral edge includes regions of a substantially continuous configuration with radii are such that their optical centers either within the optic or outside the optic and also being substantially smaller the radius of the optic of equivalent dimension but circular shape of substantially constant radius. The peripheral edge surface has a substantially flat configuration in the direction between the surfaces. The intersection of the peripheral edge surface and at least one of the anterior surface and the posterior surface, forms a discontinuous sharp corner edge.
