摘要： A method of photodisruptive laser surgery includes selecting a target region of a tissue for fragmentation, directing a beam of laser pulses to the selected target region of the tissue, and forming cells in the target region of the tissue by directing the laser beam to generate cell boundaries. The cells can be arranged in regular or irregular arrays. The cells can be generated in parallel or successively, with cell sizes and laser parameters which reduce the time of ophthalmic surgery considerably.

摘要： The present invention generally relates to a method and system for determining the position and alignment of a plane in relation to an intersecting axis and using that known position and alignment to allow for corrections to be made when using the plane as a reference plane. More particularly, the invention relates to a method and system for determining the angle of tilt of a planar surface in relation to a laser beam, and using the determined angle of tilt to calculate a correction factor to be applied to the laser beam. Briefly stated, the method and system ultimately calculates a correction factor, z-offset, that is applied when using the laser beam in a procedure.

摘要： A laser scanner is disclosed. The laser scanner comprises a laser source, a first optical element, and a focusing element. The first optical element is adapted to move along the optical axis of light from the laser source. The focusing element receives laser light from the first optical element and is adapted to move orthogonally to the optical axis. Optionally, the focusing element may include multiple focusing lenses. A first focusing lens may be adapted to move along a first axis which is orthogonal to the optical axis. A second focusing lens may be adapted to move along a second axis which is orthogonal to the optical axis and to the first axis. The laser scanner may also include a second optical element which receives light from the focusing element and is adapted to effectively increase the focal length of the focusing element without increasing its f number.

摘要： An electronically controlled fixation light system is described for ophthalmic systems. The ophthalmic system can include an ophthalmic imaging device that generates an image of a portion of an imaged eye, a fixation light controller that includes an input module, configured to receive an input in relation to the image generated by the ophthalmic imaging device, and a control signal generator that generates an electronic fixation light control signal in response to the received input, and a fixation light source, configured to receive the fixation light control signal, and to generate a fixation light according to the received fixation light control signal. A surgeon can image a portion of an eye with the imaging device, determine a misalignment of the imaged eye relative to the imaging device based on the image, and control the fixation light with an electronic control signal to reduce the determined misalignment.

摘要： Techniques and systems for gradient search are provided based on sensing or measuring at selected locations of a target object without performing full-field sensing or measuring over the entire field of the target object. Search methods are provided to include determining a coordinate of a boundary of a region in relation to a loop in a proximity of a first location, determining a direction of a gradient of the coordinate corresponding to the first location, and selecting a second location based on the determined direction. A search system can be implemented to include an imaging system to determine a coordinate of a feature of an object on a loop in a proximity of a first location, and a controller, coupled to the imaging system, to determine a direction of a gradient of the coordinate corresponding to the first location, and to select a second location based on the determined direction.

摘要： Systems and techniques for laser surgery based on imaging a target tissue by nonlinear scanning are presented. In one implementation, a method for guiding an eye surgery can include the steps of: positioning an eye in relation to an imaging system; creating first scan data by determining a depth of an eye target region at a first set of points along a first arc; creating second scan data by determining a depth of the eye target region at a second set of points along a second arc; determining target region parameters based on the first and second scan data; and adjusting one or more surgical position parameters according to the determined target region parameters.
