    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: 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: 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 translation: 用于在目标眼组织（例如视网膜）上产生瞄准和治疗光的图案P的系统和方法。 该系统包括用于治疗和瞄准光的光源，用于产生所产生的光斑的扫描器，控制器和图形用户界面，其允许用户选择几种可能的斑点图案之一，调整斑点密度和/ 或斑点尺寸，并应用固定或不同密度的图案。 图案可以由交错的子图案形成和/或扫描，而没有相邻的点被连续地形成以减少局部加热。 图案中的部分或全封闭排除区域可保护敏感的目标组织免受光线的侵害。
