Abstract: 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.

Abstract: A laser eye surgery system produces a treatment beam that includes a plurality of laser pulses. An optical coherence tomography (OCT) subsystem produces a source beam used to locate one or more structures of an eye. The OCT subsystem is used to sense the distance between a camera objective on the underside of the laser eye surgery system and the patient's eye. Control electronics compare the sensed distance with a pre-determined target distance, and reposition a movable patient support toward or away the camera objective until the sensed distance is at the pre-determined target distance. A subsequent measurement dependent upon the spacing between the camera objective and the patient's eye is performed, such as determining the astigmatic axis by observing the reflection of a plurality of point source LEDs arranged in concentric rings off the eye.

Abstract: A laser surgical method for performing a corneal incision while maintaining iris exposure below a predetermined exposure limit includes: determining an initial iris exposure based on an initial treatment scan, determining whether the initial iris exposure is less than the predetermined exposure limit; generating a revised treatment scan comprising one or more treatment scan modifying elements when the initial iris exposure is greater than the predetermined exposure limit, and scanning the focal zone of a pulsed laser beam according to the revised treatment scan, thereby performing the corneal incision, wherein the one or more treatment scan modifying elements causes the iris exposure to be smaller than the predetermined exposure limit.

Abstract: A method for measuring the intraocular pressure (IOP) of an eye docked to an ophthalmic surgical laser system via a patient interface assembly. While the eye is docked to the laser system, and as the vertical force exerted on the eye by the patient interface fluctuates as the patient breaths and moves, the amount of corneal deformation is continuously measured by an optical coherence tomography device of the laser system and the force exerted on the eye is continuously measured by force sensors integrated in the patient interface assembly. Based on the real-time force signal and real-time corneal deformation signal, a controller calculates a linear relationship between force and corneal deformation, and determines the IOP of the docked eye by comparing a slope of the linear relationship against a pre-established slope vs. IOP calibration curve. The IOP of the docked eye can be used when setting laser treatment parameters.

Abstract: In an ophthalmic laser surgical system, a real-time optical coherence tomography (OCT) measurement method acquires OCT data during laser treatment. The treatment laser beam and OCT sample beam are generated simultaneously, and the optical delivery system scans them simultaneously in the eye tissue, where the focus of the treatment laser beam and the focus of the OCT beam coincide with each other in space. While both beams simultaneously scanned in the eye tissue, the OCT device detects returned OCT light from the sample during a data acquisition period, and generates an OCT A-scan based on the detected OCT light. Based on the A-scan, a controller determines a structure of the eye in a depth direction relative to the focus of the OCT beam, and controls the operations ophthalmic laser surgical system accordingly. One exemplary application is the formation of an arcuate corneal incision in cataract surgery.

Abstract: In a laser delivery system for an ophthalmic laser surgery system, a laser beam scanner employs a single or two MEMS micromirror arrays. Each micromirror in the array is capable of being independently actuated to rotate to desired angles. In one embodiment, one or two micromirror arrays are controlled to scan a laser beam in two directions. In another embodiment, a micromirror array is controlled to both correct optical aberrations in the laser beam and scan the laser beam in two directions. In yet another embodiment, a micromirror array is controlled to cause the laser beam to be focused to multiple focal spots simultaneously and to scan the multiple focal spot simultaneously. The ophthalmic laser surgery system also includes an ultrashort pulse laser, a laser energy control module, focusing optics and other optics, and a controller for controlling the laser beam scanner and other components of the system.

Abstract: 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.
