Patents Assigned to Envision Diagnostics, Inc.
  • Patent number: 11717153
    Abstract: Apparatus and methods for eye tracking using an optical coherence tomography (OCT) device are disclosed. Such eye tracking may be performed by using information about the shape of the cornea and the corneal apex or using the iris/pupil border obtained using the OCT device.

  • Patent number: 11559198
    Abstract: A mask for performing an eye exam of a subject includes one or more optically transparent sections for transmitting an incident light beam therethrough and incident on the subject's eye. In some embodiments, the one or more optically transparent sections are coated with an anti-reflective coating configured to reduce reflection of the incident light beam by the one or more optically transparent sections. In some embodiments, the one or more optically transparent sections may have a portion thereof that is tilted with respect to the incident light beam when the mask is optically interfaced with the docking portion of an ophthalmic instrument, such that the incident light beam forms a finite angle of incidence with respect to the corresponding portion of the optically transparent sections.

  • Patent number: 10631725
    Abstract: An inflatable mask with two ocular cavities can seal against a user's face by forming an air-tight seal around the periphery of the user's eye socket. The sealed air-tight ocular cavity can be pressurized to take ocular measurements. The mask can conform to the contours of a user's face by inflating or deflating the mask. In addition, the distance between the user and a medical device (e.g. an optical coherence tomography instrument) can be adjusted by inflating or deflating the mask. Also disclosed herein is an electronic encounter portal and an automated eye examination. Other embodiments are also described.
