Abstract: The disclosure provides a system that may acquire, via an image sensor, an image of an eye of a person; may determine a location of an iris of the eye from the image; may determine a position of a suction ring from the image; may display, via a display, the image; may display, via the display, a first graphic overlay on the image that indicates the location of the iris of the eye;
may display, via the display, a second graphic overlay on the image that indicates the position of the suction ring; may determine multiple iris structures from the image; may determine an orientation of the eye based at least on the multiple iris structures from the image; and may display, via the display, information that indicates the orientation of the eye.

Abstract: The disclosure provides a system that may: receive data associated with multiple locations associated with a cornea of an eye; adjust at least one lens, based at least on diameter information of the data associated with at least one of the multiple locations, to set a diameter of a laser beam; and for each location of the multiple locations: determine if the eye has changed from a first position to a second position; if the eye has not changed from the first position to the second position, adjust, based at least on the location, at least one mirror; if the eye has changed from the first position to the second position, adjust, based at least on the location and based at least on the second position, the at least one mirror; produce the laser beam; and direct the laser beam to the location for a period of time.

Abstract: 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.
