    Abstract: Methods, systems, and devices are provided for measuring eye refraction without a lens, and more particularly, for measuring eye refraction with a mobile device application. An exemplary method includes measuring a distance between a patient and a mobile device, presenting to the patient one or more visual targets sized and shaped to represent perfect vision such as by using Vernier targets or grating targets, instructing the patient to indicate whether the patient can accurately read the visual targets and, if not, to move closer to the mobile device until the patient can accurately read the visual targets, calculating a vision prescription for the patient based on the visual targets and a final distance between the patient and the mobile device, and displaying the vision prescription for the patient.

The fixation projection system is configured to project fixation light flux onto a fundus of a subject's eye. The interference optical system includes an optical scanner and is configured to split light from light source into measurement light and reference light, to irradiate the subject' eye with the measurement light deflected by the optical scanner, and to detect interference light between returning light of the measurement light from the subject's eye and the reference light. The controller is configured to perform OCT measurement on a first scan region and a second scan region, which are different from each other in the subject's eye, by controlling the interference optical system in a state where a projected position of the fixation light flux on the fundus is fixed.

  • Publication number: 20200397283
    Abstract: The invention relates to a method to quantify human corneal tissue parameters to improve biomechanical modelling of refractive and therapeutic procedures to reduce or eliminate refractive errors and unwanted wavefront aberrations. The analysis of the preoperative biomechanical properties of cornea assists in predicting the postoperative biomechanical response of cornea. The computational models of extreme properties of the corneal tissue are conducted and the 3-D finite element models are populated with tomographic information of the cornea and artificial intelligence is trained to consider the pre-operative characteristics of the corneal tissue. The post-operative refractive procedures are simulated using the said finite element models. Finally, biomechanical deformations are prospectively estimated and method builds a deep learning approach to link clinical features to changes in biochemical outcomes.

For example, a product may include one or more tangible computer-readable non-transitory storage media including computer-executable instructions operable to, when executed by at least one computer processor, enable the at least one computer processor to implement operations of measuring a pupillary distance between pupils of a user. The operations may include receiving a captured image comprising first and second reflections of a light of a light source, the first reflection comprising a reflection of the light from a first pupil of the user, and the second reflection comprising a reflection of the light from a second pupil of the user; and determining the pupillary distance based on locations of the first and second reflections in the captured image and an estimated distance between an image capturing device and pupils of the user, when the image is captured.
