摘要： A method of imaging and treating ocular tissue of an eye having a cornea, an iris, an anterior chamber, an irido-corneal angle, and a direction of view includes establishing a common optical path through the cornea and the anterior chamber into the irido-corneal angle for each of an optical coherence tomography (OCT) beam and a laser beam, where the common optical path is offset from an optical axis within the direction of view. The method also includes obtaining a circumferential OCT image of the irido-corneal angle, obtaining an azimuthal OCT image of the irido-corneal angle, and determining a treatment pattern for a volume of ocular tissue of the irido-corneal angle based on the circumferential OCT image and the azimuthal OCT image. The method further includes delivering optical energy through the laser beam in accordance with the treatment pattern.

摘要： 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.

摘要： A target volume of ocular tissue is treated with a laser having a direction of propagation toward the target volume, where the target volume is characterized by a distal extent, a proximal extent, and a lateral extent. A layer of tissue at an initial depth corresponding to the distal extent of the target volume is initially photodisrupted using a femtosecond laser by scanning the laser in multiple directions defining an initial treatment plane. Tissue at one or more subsequent depths between the distal extent of the target volume and the proximal extent of the target volume is subsequently photodisrupted using a femtosecond laser by moving a focus of the laser in a direction opposite the direction of propagation of the laser and then scanning the laser in multiple directions defining an subsequent treatment plane. Photodisruption is repeated at different subsequent depths until tissue at the proximal extent of the target volume is photodisrupted.

摘要： 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.

摘要： 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.
