  • Method and arrangement for eye pressure measurements
    Patent number: 11659994
    Abstract: An intraocular pressure measurement arrangement is disclosed for measuring pressure of an eye of a patient. The arrangement can include at least one source for producing mechanical waves of several frequencies from a distance to the eye of the patient to generate at least one surface wave to the eye, a detector for detecting at least one surface wave from a distance from the eye to extract surface wave information, and a device for determining pressure information of the eye based on the surface wave information.
    Type: Grant
    Filed: June 4, 2021
    Date of Patent: May 30, 2023
    Assignee: PHOTONO OY
    Inventors: Antti Kontiola, Edward Häggström, Ari Salmi, Heikki Nieminen
