  • Patent number: 11294179
    Abstract: A small imager mounted on a user's eye (referred to as a femtoimager) is coordinated with an external camera. The femtoimager may be contained in a contact lens, and it may be aligned with the gaze a user's eye. The femtoimager and external camera capture images with overlapping views of the external environment. Images from the two imagers may be compared with one another to estimate the femtoimager's view of the external environment relative to the camera's view of the external environment. This may then be used for different applications.

  • Patent number: 11234593
    Abstract: In a slit lamp microscope, ease of maintenance of an illumination-power-supply cable is improved while preventing the cable from appearing untidy. An illumination support arm of a slit lamp microscope is provided with a groove-shaped cable holder in which the illumination-power-supply cable is disposed along the outer surface of the illumination support arm in an externally exposed state. This configuration facilitates replacement of the illumination-power-supply cable even when a problem, such as breaking of the illumination-power-supply cable, occurs, thus improving ease of maintenance. Furthermore, because the illumination-power-supply cable is disposed along the groove-shaped cable holder, the slit lamp microscope has a neat appearance.

    Abstract: A camera capable of quickly updating a region of interest (ROI) in its sensor array is provided. The camera is configured to image individual scan lines of a scan imager created as a scan beam is scanned across a subject. A different ROI is defined for each scan line to be imaged. To achieve this, a table of ROI-defining entries is loaded into the camera prior to imaging the scan lines. The ROI-defining entries are used to update the sensor's ROI during the camera's Frame-Overhead-Time. In this manner, the ROI is changed in between the imaging of consecutive scans lines.

  • Patent number: 10984756
    Abstract: A display system divides a screen into regions and applies a different set of rendering/encoding parameters to each region. The system applies a first set of parameters to a first region that is being viewed by a fovea of an eye of a user. The system may also apply a second set of parameters to a second region that is being viewed by a parafovea of the eye, and apply a third set of parameters to a third region that is being viewed by the area of the eye outside of the parafovea. The first set of parameters are selected to yield relatively high image quality, while the second set of parameters are yield intermediate quality, and the third set of parameters yield lower quality. As a result, the second region and the third region can be rendered, encoded, and transmitted with less computing power and less bandwidth.

  • Patent number: 10966607
    Abstract: Techniques for measuring optical aberrations of the eye are disclosed. An example method comprises positioning the eye in a measurement location adjacent to a measurement arm of an optical coherence tomography (OCT) interferometer apparatus, so that source light from the measurement arm passes into the anterior segment of the eye and detecting an interference pattern, the interference pattern resulting from a combination of light reflected from the eye and light reflected from a reference arm of the OCT interferometer apparatus. Based on the interference pattern, an optical delay between a reference surface in the anterior segment of the eye and a measured surface in the eye is calculated, the reference surface being the anterior surface of the cornea or the lens, wherein said calculating comprises measuring an optical phase shift between the reference surface and the measured surface, based on the detected interference pattern.

  • Patent number: 10631724
    Abstract: An optical measurement instrument performs a series of wavefront measurements to obtain a plurality of sets of wavefront aberrometry data for an eye, and performs a series of corneal topography measurements to obtain a plurality of sets of corneal topography data for the eye. Each set of wavefront aberrometry data is obtained at a corresponding different point in time, and each set of corneal topography data is obtained at a corresponding different point in time. The wavefront aberrometry data and the corneal topography data are processed to produce combined tear film breakup data as a function of time. The combined tear film breakup data may be employed as a metric for evaluating a level of tear film breakup of the eye as a function of time.

  • Patent number: 10595720
    Abstract: Improvements to user interfaces for ophthalmic imaging systems, in particular Optical Coherence Tomography (OCT) systems are described to improve how diagnostic data are displayed, analyzed and presented to the user. The improvements include user customization of display and reports, protocol driven work flow, bookmarking of particular B-scans, accessing information from a reference library, customized normative databases, and ordering of follow-up scans directly from a review screen. A further aspect is the ability to optimize the contrast and quality of displayed B-scans using a single control parameter. Virtual real time z-tracking is described that maintains displayed data in the same depth location regardless of motion.
