摘要： A system and method are provided for fragmenting a crystalline lens, to facilitate its removal from the lens bag during an ophthalmic laser surgery. First, a predetermined pattern is used to make Laser Induced Optical Breakdown (LIOB) cuts that section the lens into asymmetrical, operational segments. At least one operational segment is then selected and softened with a plurality of compact LIOB cuts. Once softened, the selected segment is aspirated. The remaining operational segments are then subsequently removed. During a procedure, an imaging unit can monitor movements of the lens bag to ensure proper placement of the LIOB cuts on the lens.

摘要翻译：提供了一种用于使晶状体碎裂的系统和方法，以便于在眼科激光手术期间从晶状体袋移除晶状体。首先，使用预定的图案来制造将透镜划分为不对称的，可操作的部分的激光诱导光学分解（LIOB）切割。然后，利用多个紧凑的LIOB切割来选择和软化至少一个操作段。一旦软化，所选择的部分被吸出。其余的操作段随后被移除。在一个过程中，成像单元可以监控透镜袋的运动，以确保LIOB切口在透镜上的正确放置。

摘要： A system and method are disclosed for using a laser unit to treat a crystalline lens (or lens capsule) to compensate for any tilt angle “φ” there may be between a lens axis and an operational axis of the laser unit (i.e. “z” axis). To begin, a contiguous sequence of procedure paths that collectively define the boundary surface of a lens volume are identified, with each procedure path inclined by the tilt angle “φ”. A slice occurs in an x-y plane that is on the boundary surface of the volume of lens and includes portions of several procedure paths. The slices are projected into the x-y plane where they are sequenced for use as trace paths for the laser unit. The trace paths are used to guide a laser beam to perform LIOB along the slice for the different values of “z” to incise the boundary surface.
摘要翻译：公开了一种用于使用激光单元来处理晶状体（或透镜胶囊）来补偿任何倾斜角度“＆phgr”的系统和方法，其可以在透镜轴和激光单元的操作轴之间（即“z” “轴”）。为了开始，识别共同定义透镜体积的边界表面的连续的程序路径序列，每个过程路径倾斜倾斜角“＆phgr”。切片出现在透镜体积的边界表面上的x-y平面中，并包括几个程序路径的部分。切片被投射到x-y平面中，在这些平面上它们被排序用作激光单元的迹线路径。迹线路径用于引导激光束沿着切片执行LIOB以获得不同的“z”值来切割边界表面。

摘要： A system and method for creating a line recognition template that replicates an object is provided for use as a control reference during ophthalmic surgery on the object. Creation of the template first requires aligning a plurality of reference points along a central “z” axis, with anatomically measured lengths (Δ“z”n) between adjacent reference points. Axially-symmetric surfaces can then be traced between selected, adjacent, reference points to create the template. For the present invention, the location of reference points, and the tracing of axially-symmetric surfaces, are based on a cross sectional image of the object for surgery. Preferably, the cross sectional image is obtained using Optical Coherence Tomography (OCT) techniques.

摘要： A system and method for performing a femto-fragmentation procedure on tissue in the crystalline lens of an eye requires that a laser beam be directed and focused to a focal point in the crystalline lens of the eye. The focal point is then guided, relative to an axis defined by the eye, to create a segment cluster by causing Laser Induced Optical Breakdown (LIOB) of tissue in the crystalline lens. The resultant segment cluster includes a plurality of contiguous, elongated segments in the crystalline lens that are individually tapered from an anterior end-area to a posterior end-area. Specifically, this is done to facilitate the removal of individual segments from the segment cluster in the crystalline lens.

摘要： A system and method are provided wherein an operational characteristic of a laser beam is identified. A predetermined ophthalmic reference datum is also identified. The identified laser beam characteristic is then used in its relationship with the reference datum for guidance and control of the laser beam's focal point. In operation, the laser beam's focal point is moved through eye tissue while minimizing any deviations of the operational characteristic of the laser beam from the reference datum.

摘要： A system, apparatus, and method may provide laser beams of two or more wavelengths from diode pumped solid-state laser sources (220, 222, 224). The beam paths of these laser beams with different wavelengths, which are generated by the laser sources (220, 222, 224), may be aligned along a common optical axis 280 by an optical configuration, to treat at least one target area. Frequency-doubled laser beams, output from a plurality of diode pumped solid state laser cavities, may be passed through fold mirrors (M2, M5, M8), and combined on a common optical axis 280, using one or more combiner mirrors (M10, M11, M12), to unify the beam paths. Selected laser beams may be delivered to a target using one or more delivery systems.
