    摘要： A system and method for performing Laser Induced Optical Breakdown (LIOB) on a target tissue includes a detector for imaging the interface surface between the target tissue and a base tissue. Also included is a laser unit for generating a laser beam, and for focusing the laser beam to a focal point. A computer is provided for controlling movement of the focal point. Specifically, this control is accomplished to maintain the focal point in the target tissue, but beyond a predetermined distance from the interface surface. For the present invention, the predetermined distance is established by considerations of laser beam geometry, which are applied in the context of images that are created of the interface surface.

    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 and its method for treating targeted tissue in the vitreous cavity of an eye include a laser unit for generating a laser beam and a detector for creating an image of the targeted tissue. The system also includes a computer which defines a focal spot path for emulsifying the targeted tissue. A comparator that is connected with the computer then controls the laser unit to move the focal spot of the laser beam. This focal spot movement is accomplished to treat the targeted tissue, while minimizing deviations of the focal spot from the defined focal spot path.

    摘要： A system and method are provided for obviating Posterior Capsule Opacification (PCO) which require an Optical Coherence Tomography (OCT) device for imaging the interface surface between the posterior surface of an intraocular lens (IOL) and the capsular bag. Further, the OCT device is used to identify areas of relative opacity caused by a biological growth on the interface surface in the optical zone of the IOL. A laser unit is then used to direct the focal point of a femtosecond laser beam onto the areas of relative opacity to ablate the biological growth by Laser Induced Optical Breakdown (LIOB) to thereby obviate the PCO.

The system also includes a computer which defines the microchannel. A comparator that is connected with the computer then controls the laser unit to move the focal point of the laser beam. This focal point movement is accomplished to create the microchannel, while minimizing deviations of the focal point from the defined microchannel.
