20120259320 | System and Method for Performing Lens Fragmentation - 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. | 10-11-2012 |
20130072915 | System and Method for Moving the Focal Point of a Laser Beam - 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. | 03-21-2013 |

20130103010 | System and Method for Laser Ablation on a Surgical Surface - 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. | 04-25-2013 |
20130103011 | System and Method for Lowering IOP by Creation of Microchannels in Trabecular Meshwork Using a Femtosecond Laser - 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. | 04-25-2013 |
20130103012 | System and Method for Obviating Posterior Capsule Opacification - 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. | 04-25-2013 |
20130103015 | OCT-Guided Femtosecond Laser to Measure a Retinal Surface for Use in Performing an Intra-Retinal Ablation - 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. | 04-25-2013 |
20130289543 | SYSTEM AND METHOD FOR IN SITU CREATION OF A SMALL APERTURE INTRAOCULAR LENS - A system and method are provided for altering the optical characteristics of an Intraocular Lens (IOL), in situ, using laser techniques. Specifically, a computer-controlled laser unit either creates microbubbles, or converts inclusions, inside the IOL, to establish a predetermined optical barrier having a predetermined opacity. The resultant optical barrier is oriented in the IOL to control light passing through the IOL, and to thereby minimize or correct adverse optical effects that would otherwise be present. | 10-31-2013 |

20130345683 | SYSTEM AND METHOD FOR GENERATING TREATMENT PATTERNS - A method of treating target tissue of an embodiment comprises: selecting a treatment pattern of spots; generating an aiming beam of aiming light; translating the aiming beam to form an aiming pattern of the aiming light on the target tissue that indicates the extent of the treatment pattern; generating a treatment beam of treatment light; and translating the treatment beam to form the selected treatment pattern of spots of the treatment light on the target tissue. | 12-26-2013 |
20140135749 | SYSTEM AND METHOD FOR FEMTO-FRAGMENTATION OF A CRYSTALLINE LENS - 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. | 05-15-2014 |
20140135751 | SYSTEM AND METHOD FOR INCISING A TILTED CRYSTALLINE LENS - 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. | 05-15-2014 |
