  • Patent number: 10863899
    Abstract: Systems and methods for locating the center of a lens in the eye are provided. These systems and methods can be used to improve the effectiveness of a wide variety of different ophthalmic procedures. In one embodiment, a system and method is provided for determining the center of eye lens by illuminating the eye with a set of light sources, and measuring the resulting first image of the light sources reflected from an anterior surface of the lens and the resulting second image of the light sources reflected from a posterior surface of the lens. The location of the center of the lens of the eye is then determined using the measurements. In one embodiment, the center of the lens is determined by interpolating between the measures of the images. Such a determination provides an accurate location of the geometric center of the lens.

  • Publication number: 20200188168
    Abstract: Embodiments of this invention relate to systems and methods for automatic depth (or Z) detection before, during, or after laser-assisted ophthalmic surgery. When performing ophthalmic laser surgery, the operator (or surgeon) needs to make accurate and precise incisions using the laser beam. With the automatic depth detection systems and methods, the same laser used for the surgical procedure may be used for depth measurement of the surgical incisions. The surgical laser system may include a laser delivery system for delivering a pulsed laser beam to photoalter an eye, a mirror to transmit at least a portion of reflected light of the pulsed laser beam, a lens positioned to focus the transmitted reflected lighted on to a detector, (such as a CCD), and a depth encoder configured to automatically detect depth according to one or more of color, intensity, or shape of the focused spot on the CCD.

  • Patent number: 9877649
    Abstract: Systems and methods are provided for performing a photorefractive assessment. The system comprises a computing device including an image-capturing device, a display device, and a computer application that is executable on the computing device and operable to perform a method including receiving input specifying subject information, capturing an image using the image-capturing device containing eye pupils of a subject, and analyzing the image captured to determine a distance between the subject and the image-capturing device using the subject information and predetermined interpupilary distance information. A remediation action may be performed if the distance determined is not within an appropriate distance range for the photorefractive assessment. An illuminance level of the environment may be analyzed using the image captured to determine whether lighting conditions are appropriate for performing the photorefractive assessment.

  • Publication number: 20170112373
    Abstract: Systems and methods are provided for managing, optimizing subject information, recommending ophthalmologic assessments, and performing diagnostic assessments. The system includes a computing device having an image-capturing device and a display. The system includes a computer application that is executable on the computing device and operable to receive information regarding a subject, recommend ophthalmologic tests based on the information received, and perform ophthalmologic assessments on a subject. Performance of the ophthalmologic assessments causes the application to generate information regarding the ophthalmologic health of the subject, analyze the information generated, and present results of the analysis on the display.

  • Patent number: 9521949
    Abstract: Systems and methods for analyzing the anatomy of a patient's eye with circular or rotated polarized laser beams, or with laser beams of different wavelengths are disclosed. One system includes a polarization beam-splitter and a quarter-wave plate, wherein the quarter-wave plate is configured to circularly rotate a laser beam received from a laser that is transmitted and passes through the polarization beam-splitter, and to transform a circularly rotated back-reflected beam to a linearly polarized laser beam that is perpendicular to the beam that was transmitted through the polarization beam-splitter. Substantially all of the back-reflected beam is directed to a photo-detector for analysis. A Faraday rotator subsystem may be substituted for a polarization beam-splitter. An optical system including a laser that generates a laser beam of a first wavelength for therapeutic treatment, and another laser that generates a laser beam of a second wavelength for measurement is also disclosed.
