    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 laser system for eye surgery comprises a laser source for emitting a laser beam and a beam delivery means to direct the laser beam to a position where a patient's eye is located. The beam delivery means within a beam delivery arm is arranged at an angle α with respect to the direction of the beam when emitted from the laser source. The angle α is in a range of 105° to 165°, preferably in a range of 115° to 155°, and more preferably the angle α is approximately 135°. The system may comprise a device body in which the laser source may be arranged. The beam delivery means may comprise a beam delivery arm extending to a position above the patient's eye. Preferably, the laser source is arranged to emit the laser beam in a direction from the head to the feet of the patient when being positioned for surgery. That is, the laser beam is emitted in a direction away from an operator of the device.

    摘要： A device for calibrating a laser beam system includes a calibration member having a surface positioned at a predetermined distance from the base datum of the unit. Further, the system includes a mechanism for focusing the beam to a focal point and for moving the focal point relative to the surface of the calibration member. When the focal point reaches the surface of the calibration member, Laser Induced Optical Breakdown (LlOB) is induced. Thereafter, the position of the location of LIOB may be measured relative to the base datum to calibrate the laser beam. Further, patterns may be applied to the calibration member using LIOB to calibrate tilt/decenter of the beam and to determine the energy density and uniformity in the focal spot of the laser beam.
