Abstract: An optical switch incorporated in a photomedical system, and a method of treating tissue using the optical switch for creating pulsed light. A light source generates an optical beam. An aperture element includes a light-transmitting portion and a light-blocking portion. An optical element such as a mirror, prism or lens directs the optical beam to the aperture element, wherein the optical element is movable for translating the optical beam across the light-transmitting and light-blocking portions of the aperture element, or changing its angle of incidence through the aperture to produce one or more pulses of light from the optical beam. A lens focuses the one or more pulses of the optical beam onto target tissue. A controller controls the movement of the optical element to produce the one or more pulses of light.

Abstract: System and method for generating patterns P of aiming and treatment light on target eye tissue (e.g. the retina) of a patient's eye. The system includes light sources for treatment and aiming light, a scanner for generating patterns of spots of the generated light, a controller, and a graphic user interface that allows the user to select one of several possible spot patterns, adjust the spot density and/or spot size, and apply patterns with fixed or varied density. The patterns can be formed of interlaced sub-patterns and/or scanned without adjacent spots being consecutively formed to reduce localized heating. Partially or fully enclosed exclusion zones within the patterns protect sensitive target tissue from exposure to the light.

Abstract: A method of treating target tissue of an embodiment comprises: selecting a treatment pattern of spots; generating an aiming beam of aiming light; translating the aiming beam to form an aiming pattern of the aiming light on the target tissue that indicates the extent of the treatment pattern; generating a treatment beam of treatment light; and translating the treatment beam to form the selected treatment pattern of spots of the treatment light on the target tissue.
