  • Patent number: 10828197
    Abstract: A device for producing control data for a laser device for the surgical correction of defective vision. The device generates the control data to control the laser, the optics and the scanner to cut the cornea by focusing the laser radiation and by shifting the position of the focus within the cornea. The control data controls the scanner to shift the position of the focus within the cornea. The device generates the control data such that the laser, the optics and the scanner emit and focus the laser radiation such, that a volume in the cornea is isolated. The removal of which volume from the cornea effects a desired correction of the defective vision. To determine the control data, the device is configured to calculate a radius of curvature Rcv* of the cornea reduced by the volume wherein the radius of curvature Rcv* is locally varying.

    Abstract: A method and device for non-invasive monitoring of the temperature of the retina and the retinal pigment epithelium inside the eye, particularly during heating of the bottom of the eye, wherein alternating probing short-duration pulses of light, one at wavelength close to the absorption maximum of the photoreceptor cell type and the other at wavelength in the near-infrared region, are directed at the retinal tissue at appropriate time intervals. Photoreceptor cell electrical signals, photoresponses, are recorded using electroretinography (ERG) and the changes in retinal temperature are determined from changes in photoresponse kinetics and changes in photoreceptor sensitivity to the stimuli. The method is especially applicable at temperatures up to 45° C. for humans and for other animals.

  • Patent number: 10694941
    Abstract: A device for determining biometric variables of the eye, as are incorporated in the calculation of intraocular lenses including a multi-point keratometer and an OCT arrangement. The keratometer measurement points are illuminated telecentrically and detected telecentrically and the OCT arrangement is designed as a laterally scanning swept-source system with a detection region detecting the whole eye over the whole axial length thereof. The multi-point keratometer ensures that a sufficient number of keratometer points are available for measuring the corneal surface. By contrast, telecentricity ensures that the positioning inadequacies of the measuring instrument in relation to the eye to be measured do not lead to a local mismatch of the reflection points. The swept-source OCT scan detects the whole eye over the length thereof so that both anterior chamber structures and retina structures can be detected and a consistent whole eye image can be realized.

This image display device is provided with the following: a distance computation unit that computes the distance to a subject in a field-of-view image; a visual-acuity-information acquisition unit that stores visual-acuity information for the user in advance; a corrected-image generation unit that generates and outputs a corrected image on the basis of the field-of-view image and an eye image generated from the field-of-view image, the distance information, and the visual-acuity information; and a display unit that displays the corrected image by superimposing same onto the user's field of view. Since the corrected image is superimposed without the use of lenses, lenses being the cause of the abovementioned distortion, the user can see close objects clearly.

  • Patent number: 9700204
    Abstract: An ophthalmological device emits light from a measurement optical system to an eye to be examined and calculates a dimension along the eye axis of a target portion of the eye from interfering light composed of reflected light from the eye and reference light. The measurement optical system includes incidence position changing member that changes the incidence position of light emitted to the eye, and driving unit that drives the incidence position changing member so as to scan at the incidence position of emitted light in a predetermined region of the eye. The predetermined region is a region where a straight line passes through when the straight line radially extended from the cornea apex of the eye is circumferentially moved over a predetermined angle range in the case of the eye is viewed from the front.

  • Patent number: 9696134
    Abstract: A system (10) for measuring a physical characteristic of an object (11) using dual path, two-dimensional Optical Coherence Tomography (OCT) includes an extended broadband light source (13) producing an incident light beam (14) and an interferometer (15) having a beam splitter (16) that splits the incident beam into first and second component (17, 18) beams and directs the second component beam (18) on to a moveable mirror (19) for creating an optical path difference between the first component beam (17) and a reflection (20) of the second component beam. A focusing lens (21) having a focal plane (22) focuses the first component beam and the reflection of the second component beam to form a fringe pattern (23) on the focal plane, and a configurable imaging system (25) images the fringe pattern on to a plane (12) of the object to allow two-dimensional measurement of the object without spatial scanning.

  • Patent number: 9510748
    Abstract: Embodiments of this invention relate to the generation of wavefronts for measurements, diagnostics, and treatment planning for ophthalmic applications. In some embodiments, a wavefront generator generates light having a uniform wavefront, which is focusable on the retina of an emmetropic eye by the normal function of the emmetropic eye. In some embodiments, the wavefront generator can generate light having a custom wavefront which is not focusable on the retina of the emmetropic eye. In some embodiments, the wavefront generator can receive information relating to an optical aberration of the eye, generate a custom wavefront, and project light having this custom wavefront, which in combination with the optical aberration of the eye is focusable on the retina.

  • Patent number: 9504378
    Abstract: The present disclosure relates generally to a system and method for determining the refractive error of a person, more particularly determining the person's refractive error by using a computerized screen, and providing the person with a prescription for the person's preferred type of corrective lenses. The system and method do not require the trip or expense of a doctor visit, and are optimized for convenience and cost effectiveness. In a general embodiment, the present disclosure provides a method for determining a corrective lenses prescription for a person. The method includes, separately, for each eye of the person, determining the sphere prescription for the person via a computerized screen and without the use of a refractor lens assembly. Determining the sphere prescription is done, in part, by displaying a sphere figure to the person via the computerized screen and enabling the person to select at least one input, where the input corresponds to a sphere measurement.
