Patent ID: 8568393

Claim:
A method of performing therapy on target eye tissue of a patient, comprising: producing a beam of light; deflecting the beam of light to produce a light beam pattern at a first angular orientation using a scanning device; reflecting the light beam pattern onto the target eye tissue using an ophthalmic lens assembly with a reflective optical element; rotating the reflective optical element to a first position to angularly align the light beam pattern at the first angular orientation to the target eye tissue; applying the light beam pattern onto the target eye tissue with the reflective optical element in the first position; orienting the light beam pattern at a second angular orientation that is separated from the first angular orientation by a predetermined angle RA; manually rotating the reflective optical clement, using the light beam pattern at the second angular orientation as visual guidance, to a second position to angularly align the light beam pattern at the second angular orientation to the target eye tissue; and applying the therapeutic light beam pattern onto the target eye tissue with the reflective optical element in the second position; wherein the predetermined angle RA is selected such that the light beam patterns applied to the target eye tissue with the reflective optical element in the first position and the second position, adjacently abut each other on the target eye tissue.
