  • Patent number: 10295816
    Abstract: A surgical microscope employs a pentaprism beam splitter as a branching unit to branch each beam passed through variable power optical systems into a first beam and a second beam, the first beam being horizontally reflected for an eyepiece unit, the second beam being vertically transmitted for an imaging device. The pentaprism alone is capable of simultaneously conducting reflection to provide an erect image and transmission to provide a photographing image, thereby reducing the number of optical parts in a microscope body of the surgical microscope.

  • Patent number: 10292864
    Abstract: Embodiments of the present invention encompass systems and methods for generating a vision treatment target for an eye of a patient. Exemplary techniques can involve obtaining a wavefront measurement for the eye of the patient, processing the wavefront measurement, using a low pass filter, to obtain an ocular wavefront, and generating the vision treatment target based on the ocular wavefront. In some cases, the wavefront is processed by applying a Fourier transform to the wavefront measurement to obtain a Fourier spectrum of the wavefront, convolving, in the Fourier domain, the Fourier spectrum of the wavefront and the low pass filter to obtain a Fourier spectrum convolution result, and applying an inverse transform to the convolution result to obtain the ocular wavefront. The ocular wavefront can represent a low pass filtered version of the wavefront measurement, such that high spatial frequency features present in the wavefront measurement are not present in the ocular wavefront.

    Abstract: A display device is mounted on and/or inside the eye. The eye mounted display contains multiple sub-displays, each of which projects light to different retinal positions within a portion of the retina corresponding to the sub-display. The projected light propagates through the pupil but does not fill the entire pupil. In this way, multiple sub-displays can project their light onto the relevant portion of the retina. Moving from the pupil to the cornea, the projection of the pupil onto the cornea will be referred to as the corneal aperture. The projected light propagates through less than the full corneal aperture. The sub-displays use spatial multiplexing at the corneal surface. Various electronic devices interface to the eye mounted display.

  • Patent number: 9936866
    Abstract: According to certain embodiments, a system comprises one or more memories and one or more processors. The one or more memories store optical data from an optical recorder comprising at least two optical data sets by: receiving a first optical data set of an eye with a pupil having a first pupil size; and receiving a second optical data set of the eye with the pupil having a second pupil size. The one or more processors determine a pseudo-rotation related to a pupil size change, receive a measured cyclotorsion, calculate an actual cyclotorsion from the measured cyclotorsion and the pseudo-rotation, and adjust a laser treatment according to the actual cyclotorsion.

  • Patent number: 9931032
    Abstract: A device providing an indication of eye disease in a patient comprises a light emitter; an optical assembly arranged so that light emitted from the light emitter reaches an eye of the patient; a camera arranged to image the eye of the patient; and a controller. The controller measures the eye's pupil area using images received from the camera and adjusts the luminance of the light emitted from the light emitter as a non-constant function of the eye's pupil area so as to create a plurality of stimulus intervals. At least two of the stimulus intervals differ in their average retinal illuminance. The controller analyzes the pupil measurements and/or an electrical response in at least two of the stimulus intervals to provide an indication of eye disease based. In some embodiments, the patient's age is also used in the analysis. Methods of using said device are also contemplated.

  • Patent number: 9910294
    Abstract: A computer-implemented method for calculating or optimizing a spectacle lens for at least one eye of a spectacle wearer. Refraction data of the at least one eye of the spectacle wearer is collected. An individual eye model is defined, wherein the eye model defines at least the topography of a corneal front surface of the at least one eye, position and power of a lens of the eye, and a retina position of the eye such that the eye exhibits the collected refraction data. A first surface and a second surface for the spectacle lens to be calculated or optimized is specified. The path of a main ray through at least one visual point of at least one spectacle lens surface to be calculated or optimized is determined. A spherical wavefront incident on the first surface of the spectacle lens along the main ray is specified.

  • Patent number: 9888839
    Abstract: Methods and apparatuses for determining contact lens intolerance in contact lens wearer patients based on tear film characteristics analysis and dry eye symptoms are disclosed. In embodiments herein, imaging of the ocular tear film is performed during contact lens wear. An analysis of the image of the ocular tear film is performed to determine one or more tear film characteristics of the ocular tear film. The tear film characteristics can be used to determine the effect or possible effect of contact lens wear on the ocular tear film, and thus be used to determine contact lens intolerance of the patient. The tear film characteristics used to analyze contact lens intolerance based on images of the ocular tear film involving contact lens wear may include dry eye symptoms, including but not limited to tear film (e.g., lipid and/or aqueous) thickness, tear film viscosity, and tear film movement rate in the eye.

  • Patent number: 9867535
    Abstract: A method for determining the axial length of an eye by optical coherence tomography (OCT), in which the alignment of the measuring instrument to the eye is monitored to enable reliable determination of the axial length of the eye. B-scans are carried out following alignment from which scans of the retinal tissue structures are detected to determine the axial lengths, which are then used in the detection of the fovea in order to monitor alignment. The axial lengths determined from the B-scans are then confirmed or corrected and output depending, on the determined position of the fovea or the lateral distance thereof from the optical axis of the measuring instrument. The method is particularly suitable for OCT methods in which the axial length is determined on the basis of an A-scan along the axial dimension of the eye.
