  • Publication number: 20210093193
    Abstract: Systems and methods for tracking the position and condition of an eye during an ophthalmic procedure include an ophthalmic device configured to measure characteristics of an eye, an eye tracker configured to capture a stream of eye images, and a logic device configured to analyze the stream of images to determine whether the eye is fixating on a target object, detect a predetermined blink sequence in the first stream of images, delay for a predetermined tear stabilization period, start a stable tear film interval, and during the stable tear film interval, capture at least one measurement of the eye using the ophthalmic device when the eye is fixating. The blink sequence may include a plurality of blinks in succession and the detection of the blink sequence may include processing the images through a neural network trained to detect an open eye and/or a closed eye.

  • Publication number: 20190374102
    Abstract: Disclosed are systems and methods for aligning an ophthalmic device with respect to an eye of a patient. In one disclosure, the system may include an ophthalmic device with an on-axis and an off-axis. The system may include an on-axis illuminator that emits light that is reflected by the eye of the patient to form an on-axis reflection having a center. The system may include an on-axis camera pointed along the on-axis. The system may include an off-axis illuminator that emits light that is reflected by the eye to form an off-axis reflection having a center. The system may include an off-axis camera pointed along the off-axis. The ophthalmic device may be operable to be aligned with respect to the eye of the patient when the on-axis is substantially normal to the center of the on-axis reflection and the off-axis is substantially normal to the center of the off-axis reflection.

  • Publication number: 20190361591
    Abstract: The present disclosure provides a system that may display a graphical user interface (GUI) via a display; may receive first user input that indicates that surgical tooling equipment is to be utilized as a pointer associated with the GUI; may receive first multiple images from an image sensor; and may determine a digital model of the surgical tooling equipment, from the first multiple images, that includes a pattern of the surgical tooling equipment. The system may further train the digital model based at least on the first multiple images. The system may further receive second multiple images via the image sensor. The system may further determine, from the second multiple images and the digital model, a pattern of movement of the surgical tooling equipment that is utilizable to select of an icon of the GUI. The system may include a microscope integrated display that includes the display.

  • Publication number: 20190361592
    Abstract: The present disclosure provides a system that may display a graphical user interface (GUI) that includes an icon via a display; may receive a first image from an image sensor; may determine, from the first image and a digital model of surgical tooling equipment, a first position of the surgical tooling equipment within the first image; may display a cursor of the GUI at a second position; may receive a second image from the image sensor; may determine, from the second image and the digital model, a third position of the surgical tooling equipment within the second image; may display the cursor of the GUI at a fourth position; may receive user input that indicates a selection while coordinates of the icon include the fourth position; and may determine that the user input that indicates the selection while the coordinates of the at least one icon include the fourth position.

  • Publication number: 20190191990
    Abstract: A multi-view diagnostic system includes an OCT engine and a plurality of optical elements defining a plurality of beam paths between the OCT engine and an ophthalmic target, with each beam path corresponding to a different viewing angle of the ophthalmic target. The system also includes a scanner to direct OCT imaging beams generated by the OCT engine toward the ophthalmic target along each respective beam path. Instructions stored in memory are executable by a processor to determine a characteristic of the ophthalmic target based on OCT light reflected by the ophthalmic target along each respective beam path and detected by the OCT engine.
