  • Publication number: 20240099887
    Abstract: A system accesses a target volume of ocular tissue and treats the target volume with a laser based on the pigmentation of the tissue. A visual observation apparatus captures a color image of the target volume through an optics assembly. A control system processes the captured image and determines an energy parameter based on pigmentation of the target volume of ocular tissue. A laser source outputs a laser beam, and one or more components focus, scan, and direct the laser beam through the target volume by way of the optical assembly. The control system controls the one or more components based on a treatment pattern to place a focus of the laser beam at an initial location within the target volume of ocular tissue, and controls the laser source to apply photodisruptive energy at the initial location based on the energy parameter determined by the control system.

  • Publication number: 20230165719
    Abstract: A look-up table for use in determining an energy parameter for photodisrupting ocular tissue with a laser is generated by determining a plurality of individual spot size distributions, wherein each of the plurality of individual spot size distributions is based on a different set of simulated data and includes an expected spot size of a laser focus at each of a plurality of locations within a modeled target volume of ocular tissue. The plurality of individual spot size distributions are combined to obtain a final spot size distribution that includes a final expected spot size of the laser focus at the plurality of locations of the focus within the modeled target volume of ocular tissue. An energy value is assigned to the plurality of locations of the focus within the modeled target volume of ocular tissue based on the final expected spot size at that location.

  • Publication number: 20230128830
    Abstract: A target surface in an eye is located using a dual aiming beam apparatus that transmits a first aiming beam of light and a second aiming beam of light. An optics subsystem receives a laser beam from a laser source, the first aiming beam of light, and the second aiming beam of light, and directs the beams of light to be incident with the target surface and aligns the beams of light such that they intersect at a point corresponding to a focus of the laser beam. An imaging apparatus captures an image of the target surface including a first spot corresponding to the first aiming beam of light and a second spot corresponding to a second aiming beam of light. A separation between the spots indicates that the focus is away from the target surface, while overlapping spots indicate the focus is at or on the target surface.
