System and method for accessing different tissue targets of the eye

A method of accessing one of a plurality of target volumes of ocular tissue in an eye having an optical axis, the method comprising:

• receiving a first light beam at a first optical transmission subsystem;
• directing, by the first optical transmission subsystem, the first light beam to a select one of a plurality of first inputs axes of an optics assembly coupled to the eye, wherein the optics assembly has an optical axis and is configured to couple to the eye to align its optical axis with the optical axis of the eye;
• directing, by the optics assembly, the first light beam along the select one of the plurality of first inputs axes to a corresponding one of a plurality of first output axes of the optics assembly aligned with a corresponding one of the plurality of target volumes of ocular tissue in the eye;
• and
• rotating a housing about the optical axis of the optics assembly such that one or more components of the optics assembly rotate about the optical axis of the optics assembly and one or more components of the first optical transmission subsystem revolve around the optical axis of the optics assembly, wherein:
• the optics assembly comprises an exit lens having a convex surface to which the first light beam is incident, a concave surface opposite the convex surface, a side region that extends between the convex surface and the concave surface, and a reflecting surface associated with the side region, which receives the first light beam and redirects the first light beam through the concave surface along the corresponding first output axis,
• the one or more components of the first optical transmission subsystem are mechanically coupled to the housing, and
• the optics assembly is asymmetric and is mechanically coupled to the housing.
