Claim 20:
21. A system, comprising:
a probe that is insertable into and repositionable in an anterior chamber of an eye to perform a surgical procedure, the probe defining a probe axis that extends from a distal end of the probe, wherein the probe is configured to have an implant provided at or near the distal end of the probe, wherein the implant is configured for insertion into target tissue at a target location;
a microscope optical coherence tomography (OCT) system for generating OCT data;
a viewing device, wherein the viewing device is configured to present to a user a view of at least a portion of an eye, wherein the portion of the eye includes at least one of a trabecular meshwork and Schlemm's canal, wherein Schlemm's canal has an inner wall, wherein the view includes an OCT image produced from the OCT data, and wherein the OCT image is configured to show the target tissue, and is further configured to show at least one of the implant and the distal end of the probe when the at least one of the implant and the distal end of the probe is in a region that cannot be visualized in a microscopic image of the eye due to total internal reflection; and
at least one processor configured to:
receive, when the probe and implant have been inserted into the anterior chamber of the eye and positioned and repositioned within the anterior chamber, the OCT data, wherein the OCT data updates as the probe and implant are repositioned;
determine, from the OCT data, at least one position of at least one of the probe and the implant relative to at least one of the target location or adjacent tissue as the probe and implant are repositioned, wherein the target location is on or near at least one of the trabecular meshwork or the Schlemm's canal of the eye
cause the viewing device to display, based on the determined at least one position, at least one graphical visual element, the at least one graphical visual element including a first graphical visual element for repositioning the probe and implant such that the implant extends toward the target location, wherein the first graphical visual element updates as the probe and implant are repositioned; and
determine, from the OCT data, that the probe and implant are positioned such that the implant has reached the target location,

wherein the at least one probe is used to surgically implant the implant at the target location, and
wherein the system is configured to indicate to the user, from the OCT data, at least one of: when the trabecular meshwork has been contacted as a result of movement of the probe; and when the inner wall of Schlemm's canal has been penetrated as a result of movement of the probe.
