A method of treating a target volume of ocular tissue of an irido-corneal angle of an eye with a laser source configured to deliver optical energy sufficient to affect ocular tissue at each of a plurality of instances during a scanning of a laser beam through a scanning pattern includes placing a focus of the laser beam at an initial depth in the target volume of ocular tissue; determining one or more instances at which to prevent a delivery of optical energy sufficient to affect ocular tissue; and delivering optical energy sufficient to affect ocular tissue at each of the plurality of instances during a scanning of the laser beam through the scanning pattern except for the determined one or more instances, to thereby affect an initial treatment plane of the target volume of ocular tissue at the initial depth.

Systems and methods for performing laser operations on the structures of the eye, including the drain angle, trabecular mesh and the area of the eye where the iris and cornea meet. Laser systems and methods for treating glaucoma. Laser assisted MIGS procedures.

In certain embodiments, a patient interface apparatus for ophthalmic surgery comprises an annular member and an evacuation conduit. The annular member has an outer side, an inner side, a distal side, and a proximal side. The inner side defines an opening that allows for a laser beam to reach a treatment region of an eye free from reflection or refraction. The proximal side has a contact surface shaped to affix to a surface of the eye, and a groove that defines a suction chamber with the surface of the eye. The evacuation conduit is capable of fluid communication with the suction chamber, and conducts fluid away from the suction chamber to affix the contact surface to the surface of the eye.

An imaging probe comprises a camera or endoscope with an external detector array, in which the probe is sized and shaped for surgical placement in an eye to image the eye from an interior of the eye during treatment. The imaging probe and a treatment probe 500 can be coupled together with a fastener or contained within a housing. The imaging probe and the treatment probe 500 can be sized and shaped to enter the eye through an incision in the cornea and image one or more of the ciliary body band or the scleral spur. The treatment probe 500 may comprise a treatment optical fiber or a surgical placement device to deliver an implant. A processor coupled to the detector can be configured with instructions to identify a location of one or more of the ciliary body band, the scleral spur, Schwalbe's line, or Schlemm's canal from the image.
