  • Patent number: 10159406
    Abstract: An ophthalmic surgical apparatus including: a control device; a user interface which, at least intermittently, has data communication with the control device; a first measuring device configured for determining at least one value intraoperatively, the value being characteristic for an eye to be treated by surgery; a second measuring device configured for determining at least one value preoperatively and/or intraoperatively, the value being characteristic for the eye to be treated by surgery, and including a first computing unit which is suitable and intended, using the value determined intraoperatively and the value determined preoperatively and/or intraoperatively, for ascertaining at least one first output value which is characteristic for at least one intraocular lens to be selected, wherein the user interface at least preferably includes an output device suitable for outputting the output value or a value derived therefrom.

  • Patent number: 10058241
    Abstract: Systems and methods for performing a visual field test of a patient are described. One example method for performing the visual field test of the patient using a visual field testing device having a refractive correction element, a patient support, and a motor operably attached to one of the refractive correction element or the patient support includes positioning the patient's head relative to the device using the patient support. An image showing the position of the eye relative to the refractive correction element is collected. The relative displacement of the eye with respect to the refractive correction element is determined based on the collected image. The motor is actuated in a manner to reduce the determined displacement. A series of test stimuli is displayed to the patient's eye and responses to the test stimuli are received from the patient. The responses are analyzed to make an assessment of the patient's visual field.

  • Patent number: 9841615
    Abstract: A method for determining at least one optical design parameter for a progressive ophthalmic lens intended to be fitted in a frame of a wearer, depending on the wearer's visual behaviour, includes: a) placing the wearer in a situation in which he carries out a visual task at a first working distance; b) during this task, determining at least two gaze directions of the wearer at this first working distance in a frame of reference of the wearer's head; c) determining a relative position of a surface related to the frame or to an ophthalmic lens intended to be fitted in the frame; d) determining for each gaze direction at the first working distance the intersection between this gaze direction and the surface so as to establish a map of these points of intersection on this surface; and e) deducing the sought-after optical design parameter from this map.

  • Patent number: 8810933
    Abstract: Disclosed are a lens unit and a method of manufacturing the same. The lens unit includes a lens part including a curved region having a predetermined curvature; and a support part including a hole, in which the lens part is installed, and attached to the lens part at a lateral side of the hole. The lens part having the curvature and the support part of the lens unit are formed in separate processes such that the hole is formed in the support part having the strength, and the lens part is formed by filling the hole with the lens part, so that the movement of resin caused by shrinkage of the lens part when the lens part is cured is inhibited, and the support part and the lens part does not form the layered structure, thereby allowing the lens unit to be formed with a thin thickness.

  • Patent number: 7760448
    Abstract: A image stabilization control circuit for an image capturing device, wherein a gyro-equalizer (24) integrates an angular velocity signal from a gyro-sensor (12) in an integration circuit (46). The integration circuit (46) is composed of a low-boost filter (LBF), and a phase delay in a target compensation region is set to a value appropriate for an integration process. Furthermore, a characteristic whereby the LBF reduces the phase delay at higher frequencies is used, compensation is applied to the excess phase delay of the angular signal in the high-frequency region brought about by the effect of the phase delay generated in the high-frequency region by the output signal of the gyro-sensor (12), and the phase delay in the high-frequency region is brought nearer to 90 degrees. This allows the accuracy of the process for determining the required displacement magnitude of a lens to be increased.

  • Patent number: 7751134
    Abstract: A lens actuator is provided for moving a movable part including a lens, with respect to a fixed part in the optical axis direction of the lens. The lens actuator includes (a) a magnet disposed on the surface of the movable part facing the fixed part and magnetized in the optical axis direction, (b) a coil disposed on the surface of the fixed part facing the magnet, and (c) a pair of magnetic materials disposed on both sides of the magnet in the optical axis direction, to direct magnetic flux from the magnet toward the coil.

  • Patent number: 7616371
    Abstract: A mirror device includes a mirror, an anchor, and a spring coupling the mirror to the anchor. The anchor and/or mirror can define one or more rows of holes adjacent to the coupling location of the spring. The natural frequency of the device can be adjusted by removing material between the perimeter of the mirror/anchor and the outermost holes, and between adjacent holes in the same row. Another mirror device includes a mirror, anchors, and springs coupling the mirror to the anchors. The natural frequency of the device can be adjusted by decoupling one or more springs coupling the mirror to the anchors. The mirror of both devices can includes one or more sacrificial portions. The natural frequencies of the both devices can also be adjusted by trimming the sacrificial portions.

  • Patent number: 7170663
    Abstract: A method of forming an inorganic alignment film on a base substrate is provided comprising forming a film made substantially of an inorganic material on the base substrate, and irradiating ion beams onto the surface of the film from a direction inclined at a predetermined angle ?b with respect to the direction vertical to the surface. By irradiating the ion beams onto the film, concave portions having a predetermined directivity are formed on the film. The predetermined angle ?b is preferably 2° or more.
