摘要： The amount of energy to provide optical breakdown can be determined based on mapped optical breakdown thresholds of the treatment volume, and the laser energy can be adjusted in response to the mapped breakdown thresholds. The mapping of threshold energies can be combined with depth and lateral calibration in order to determine the location of optical breakdown along the laser beam path for an amount of energy determined based on the mapping. The mapping can be used with look up tables to determine mapped locations from one reference system to another reference system.

摘要： One embodiment is directed to a method for interfacing an ophthalmic intervention system with an eye of a patient, comprising: placing a patient interface assembly comprising a housing, an optical lens coupled to the housing, and an eye engagement assembly coupled to the housing, the eye engagement assembly comprising an inner seal and an outer seal, into contact with the eye of the patient by sealably engaging the eye with the inner and outer seals in a vacuum zone defined between the inner and outer seals; applying a vacuum load between the inner and outer seals to engage the eye using the vacuum load; and physically limiting an amount of distension of the eye in the vacuum zone.

摘要： An RF (radio frequency) positioning system and related method for automated or assisted eye-docking in ophthalmic surgery. The system includes an RF detector system on a laser head and an RFID tag on a patient interface to be mounted on the patient's eye. The detector system includes four RF antennas located on a horizontal plane for detecting RF signals from the RFID tag, where one pair of antennas are located along the X direction at equal distances from the optical axis of the laser head and another pair are located along the Y direction at equal distances from the optical axis. Based on relative strengths and phase difference of the RF signals detected by each pair of antennas, the RF detector system determines whether the patient interface is centered on the optical axis. The RF detector system controls the laser head to move toward the patient interface until the latter is centered on the optical axis.

摘要： A system and method for inserting an intraocular lens in a patient's eye includes a light source for generating a light beam, a scanner for deflecting the light beam to form an enclosed treatment pattern that includes a registration feature, and a delivery system for delivering the enclosed treatment pattern to target tissue in the patient's eye to form an enclosed incision therein having the registration feature. An intraocular lens is placed within the enclosed incision, wherein the intraocular lens has a registration feature that engages with the registration feature of the enclosed incision. Alternately, the scanner can make a separate registration incision for a post that is connected to the intraocular lens via a strut member.

摘要： A method of imaging an object includes obtaining an image data set from a raster scan. The image data set has a plurality of data points, each data point having an associated location and intensity; generating a reduced data set by selectively removing one or more data points from the image data set based upon an assigned probability of retaining the one or more data points in the data set, the assigned probability being a function of the intensity of a data point; generating a triangulation graph as a planar subdivision having faces that are triangles, the vertices of which are the data points and the edges of which are adjacent vertices; and segmenting the triangulated data set by finding a path with lowest cost between that vertex and every other vertex, wherein the cost is a function of the respective intensity of the vertices.

摘要： A method of cataract surgery in an eye of a patient includes identifying a feature selected from the group consisting of an axis, a meridian, and a structure of an eye by corneal topography and forming fiducial mark incisions with a laser beam along the axis, meridian or structure in the cornea outside the optical zone of the eye. A laser cataract surgery system a laser source, a topography measurement system, an integrated optical subsystem, and a processor in operable communication with the laser source, corneal topography subsystem and the integrated optical system. The processor includes a tangible non-volatile computer readable medium comprising instructions to determine one of an axis, meridian and structure of an eye of the patient based on the measurements received from topography measurement system, and direct the treatment beam so as to incise radial fiducial mark incisions.

摘要： The patient interface may comprise an axis for alignment with an axis of the eye such as an optical axis of the eye. The interface may comprise a guide to allow the interface to move along the axis with the eye, which can inhibit increases in intraocular pressure when the patient is aligned with the laser. The interface may comprise a lock to hold the patient interface at a location along the axis, which can maintain alignment of the patient with the laser eye surgery system. The interface may comprise a plurality of transducers to measure forces to the eye during surgery. The laser eye surgery system can be configured in one or more of many ways to respond to the measured forces. For example, the system may offset the position of laser beam pulses to increase the accuracy of the placement of the beam pulses on the eye.

摘要： Apparatus to treat an eye with an ophthalmic laser system comprises a patient interface having an annular retention structure to couple to an anterior surface of the eye. The retention structure is coupled to a suction line to couple the retention structure to the eye with suction. Liquid is added above the eye to act as a transmissive medium. A coupling sensor is coupled to the suction line to determine coupling of the retention structure to the eye. A separate pressure monitoring circuit having a much smaller volume than the suction line is connected to the annular retention structure to measure suction pressure therein. A system processor coupled to the monitoring pressure sensor includes instructions to interrupt firing of a laser when the pressure measured with a monitoring pressure sensor rises above a threshold amount.

摘要： A laser eye surgery system includes a laser to generate a laser beam. A spatial measurement system generates a measurement beam and measure a spatial disposition of an eye. A processor is coupled to the laser and the spatial measurement system, the processor comprising a tangible medium embodying instructions to determine a spatial model of the eye in an eye coordinate reference system based on the measurement beam. The spatial model is mapped from the eye coordinate reference system to a machine coordinate reference system. A laser fragmentation pattern is determined based on a plurality of laser fragmentation parameters. The laser fragmentation pattern and the spatial model is rotated by a first rotation angle such that the spatial model is aligned with the reference axis of the machine coordinate reference system and the rotated laser fragmentation pattern is aligned with the corneal incision.
