  • Patent number: 10591750
    Abstract: Techniques and mechanisms for determining a direction of gaze by a user of an ophthalmic device. In an embodiment, at least a portion of a magnetic field is generated by one of the ophthalmic device and an auxiliary reference device while the ophthalmic device is disposed in or on an eye of the user, and while the auxiliary reference device is adhered on the user's skin or under a surface of the skin. The ophthalmic device and the auxiliary reference device interact with each other via a magnetic field, and the interaction is detected with one or more sensors of the ophthalmic device. In another embodiment, the ophthalmic device stores predetermined reference information which corresponds various magnetic field signal characteristics each with a different respective direction of gaze. Based on the sensor information and the reference information, a controller of the ophthalmic device determines a direction in which the eye of the user is gazing.

  • Patent number: 10285807
    Abstract: A virtual aperture integrated into an intraocular lens is disclosed. Optical rays which intersect the virtual aperture are widely scattered across the retina causing the light to be virtually prevented from reaching detectable levels on the retina. The use of the virtual aperture helps remove monochromatic and chromatic aberrations yielding high-definition retinal images. For a given definition of acceptable vision, the depth of field is increased over a larger diameter optical zone. In addition, thinner intraocular lenses can be produced since the optical zone can have a smaller diameter. This in turn allows smaller corneal incisions and easier implantation surgery.

In one method, the lens comprises a single polymer matrix containing crosslinkable pendant groups, wherein the polymer matrix increases in volume when crosslinked. The lens does not contain free monomer. Upon exposure to ultraviolet radiation, crosslinking causes the exposed portion of the lens to increase in volume, causing an increase in the refractive index. In another method, the lens comprises a polymer matrix containing photobleachable chromophores. Upon exposure to ultraviolet radiation, photobleaching causes a decrease in refractive index in the exposed portion without any change in lens thickness. These methods avoid the need to wait for diffusion to occur to change the lens shape and avoid the need for a second exposure to radiation to lock in the changes to the lens.

  • Publication number: 20140180408
    Abstract: An intraocular lens (IOL) has an optic, a peripheral rim, and a reduced thickness region connecting the optic to the peripheral rim. The peripheral rim has a continuously curving outer edge that it does not include any tangents parallel to the optical axis either along its length or at the intersection of the outer edge with the anterior or posterior surfaces of the IOL.

  • Publication number: 20140163674
    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 retina of the eye. The optic has a central optical axis, an anterior face, an opposing posterior face and a peripheral edge between the faces. The peripheral edge has one or more curved or angled surfaces that reduce glare within the IOL. For instance, a rounded transition surface on the anterior side of the peripheral edge diffuses the intensity of reflected light, or a particular arrangement of straight edge surfaces refracts the light so as not to reflect, or does not reflect at all. The intersection of the peripheral edge and at least one of the anterior face and the posterior face, preferable both of such faces, forms a peripheral corner located at a discontinuity between the peripheral edge and the intersecting face or faces.

  • Publication number: 20140052245
    Abstract: An intraocular lens for providing vision to a subject contains an optic, a support structure coupled to the optic. The intraocular lens also includes a textured surface and/or subsurface layer. The optic is disposed about an optical axis and comprises an anterior surface and an opposing posterior surface, the surfaces being configured to focus light when implanted within an eye having a capsular bag. The textured surface is disposed over a surface portion of the intraocular lens and includes a plurality of periodically-spaced protrusions, each protrusion having a smooth distal face and a sharp corner edge configured to engage a wall of the capsular bag and/or at least one cell disposed along the wall.

    Abstract: A mask is provided that is configured to increase the depth of focus of a patient. The mask can include an aperture configured to transmit along an optical axis substantially all visible incident light. The mask can further include a portion surrounding at least a portion of the aperture. The portion may be configured to be substantially opaque to visible electromagnetic radiation and be substantially transparent to electromagnetic radiation transmitted from an ocular examination device (e.g., substantially transparent to at least some non-visible electromagnetic radiation with a wavelength between about 750 nm and about 1500 nm).
