Abstract
An apparatus and method for treating and/or diagnosing a patient's eye. A light source produces fixation light and procedure light. A scanning device deflects the fixation light to produce a fixation pattern of the fixation light on the eye, and deflects the procedure light to produce a procedure pattern of the procedure light on the eye. A controller controls the scanning device such that the fixation and procedure patterns move relative to each other, and/or the fixation pattern dynamically changes.
