Abstract: A laser indirect ophthalmoscope (LIO) apparatus for photomedical treatment and/or diagnosis is presented. The LIO apparatus allows multiple spot ophthalmic surgery to be performed in a wider range of patient positions and less intrusively than currently available methods. The LIO apparatus utilizes a separate or integral beam multiplier that generates one or more optical beams via spatial and/or temporal separation, and an optical system that conditions and directs the one or more optical beams to a target to form a pattern. The LIO apparatus includes a headset, and is therefore wearable by the user (e.g., a physician).

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: A system and method for treating target tissue including a light source for generating a beam of light, a plurality of optical fibers, a deflection device configured to selectively deflect the light beam into the input ends of the optical fibers, one optical fiber input end at a time, and a probe having a tip with the output ends of the optical fibers and configured for insertion into target tissue. The probe tip is configured to sequentially project spaced apart spots of the light beam from the output ends as the deflection device deflects the light beam into the optical fibers. One or more moving or static deflecting optics at the probe tip can be used to statically or dynamically deflect the beam exiting the optical fibers.

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 system and method for treating ophthalmic target tissue, including a light source for generating a beam of light, a beam delivery system that includes a scanner for generating patterns, and a controller for controlling the light source and delivery system to create a dosimetry pattern of the light beam on the ophthalmic target tissue. One or more dosage parameters of the light beam vary within the dosimetry pattern, to create varying exposures on the target tissue. A visualization device observes lesions formed on the ophthalmic target tissue by the dosimetry pattern. The controller selects dosage parameters for the treatment beam based upon the lesions resulting from the dosimetry pattern, either automatically or in response to user input, so that a desired clinical effect is achieved by selecting the character of the lesions as determined by the dosimetry pattern lesions.
