Abstract: 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.

Abstract: A system and method are provided for debulking scar tissue in the retina by the Laser Induced Optical Breakdown (LIOB) of scar tissue. The identification, location and extent of the scar tissue is accomplished using Optical Coherence Tomography (OCT) techniques. OCT imaging is also used to monitor the debulking procedure.

Abstract: A system and its method for creating a microchannel in the trabecular meshwork of an eye include a laser unit for generating a laser beam, and an imaging unit for creating an image of the trabecular meshwork. 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.

Abstract: A system and method are provided for combining the imaging capabilities of an Optical Coherence Tomography (OCT) device with the calculated results of ray tracing techniques. The combination is then used to derive a predictive refractive outcome for an optical model. The resultant optical model includes diopter power and size information for use in preoperative planning (e.g. a capsulotomy) and/or for the manufacture of an Intraocular Lens (IOL).

Abstract: 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.
