Abstract
An apparatus and method for treating and/or diagnosing a patient's eye. A light source produces fixation light and procedure (treatment and/or diagnosis) 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.
Claims31
An optical scanning system for treating and/or diagnosing a patient's eye, comprising:
- a light source for producing fixation light which is light for attracting and keeping said patient's gaze in a nominally fixed direction and procedure light which is light for treating and/or diagnosing said patient's eye;
- a scanning device for deflecting the fixation light to produce a fixation pattern of the fixation light on the eye, and for deflecting the procedure light to produce a procedure pattern of the procedure light on the eye;
- and
- a controller for controlling the scanning device such that at least one of the fixation and procedure patterns on the eye is moved relative to the other of the fixation and procedure patterns on the eye.
A method of treating and/or diagnosing a patient's eye, comprising:
- generating fixation light which is light for attracting and keeping said patient's gaze in a nominally fixed direction;
- generating procedure light which is light for treating and/or diagnosing said patient's eye;
- deflecting the fixation light to produce a fixation pattern of the fixation light on the eye;
- deflecting the procedure light to produce a procedure pattern of the procedure light on the eye;
- and
- moving at least one of the fixation and procedure patterns on the eye relative to the other of the fixation and procedure patterns on the eye.
