Patent number: 10441464Abstract: Systems and methods automatically locate optical surfaces of an eye and automatically generate surface models of the optical surfaces. A method includes OCT scanning of an eye. Returning portions of a sample beam are processed to locate a point on the optical surface and first locations on the optical surface within a first radial distance of the point. A first surface model of the optical surface is generated based on the location of the point and the first locations. Returning portions of the sample beam are processed so as to detect second locations on the optical surface beyond the first radial distance and within a second radial distance from the point. A second surface model of the optical surface is generated based on the location of the point on the optical surface and the first and second locations on the optical surface.Type: GrantFiled: December 12, 2016Date of Patent: October 15, 2019Assignee: OPTIMEDICA CORPORATIONInventors: Javier G. Gonzalez, Bruce Woodley

Publication number: 20190290490Abstract: The amount of energy to provide optical breakdown can be determined based on mapped optical breakdown thresholds of the treatment volume, and the laser energy can be adjusted in response to the mapped breakdown thresholds. The mapping of threshold energies can be combined with depth and lateral calibration in order to determine the location of optical breakdown along the laser beam path for an amount of energy determined based on the mapping. The mapping can be used with look up tables to determine mapped locations from one reference system to another reference system.Type: ApplicationFiled: June 10, 2019Publication date: September 26, 2019Inventors: David Angeley, Bruce Woodley, David Dewey, Michael Simoneau, Georg Schuele, Gloria Londono

Publication number: 20190231590Abstract: A laser system is calibrated with a tomography system capable of measuring locations of structure within an optically transmissive material such as a tissue of an eye. Alternatively or in combination, the tomography system can be used to track the location of the eye and adjust the treatment in response to one or more of the location or an orientation of the eye. In many embodiments, in situ calibration and tracking of an optically transmissive tissue structure such as an eye can be provided. The optically transmissive material may comprise one or more optically transmissive structures of the eye, or a non-ocular optically transmissive material such as a calibration gel in a container or an optically transmissive material of a machined part.Type: ApplicationFiled: April 8, 2019Publication date: August 1, 2019Inventors: Bruce Woodley, Javier Gonzalez

Publication number: 20190076017Abstract: A laser surgery system includes a light source, an eye interface device, a scanning assembly, a confocal detection assembly and preferably a confocal bypass assembly. The light source generates an electromagnetic beam. The scanning assembly scans a focal point of the electromagnetic beam to different locations within the eye. An optical path propagates the electromagnetic beam from a light source to the focal point, and also propagates a portion of the electromagnetic beam reflected from the focal point location back along at least a portion of the optical path. The optical path includes an optical element associated with a confocal detection assembly that diverts a portion of the reflected electromagnetic radiation to a sensor. The sensor generates an intensity signal indicative of intensity the electromagnetic beam reflected from the focal point location. The confocal bypass assembly reversibly diverts the electromagnetic beam along a diversion optical path around the optical element.Type: ApplicationFiled: November 12, 2018Publication date: March 14, 2019Inventors: Georg Schuele, Noah Bareket, David Dewey, John S.
