    Abstract: A laser eye surgery system includes a computer which scans a focused laser beam in a trajectory over a reticle or target and determines beam quality via laser light reflected from the target. The target may have a grid pattern of lines, with the diameter of the focused laser beam determined based on a time interval for the scanned beam to move onto a line of the grid pattern. Methods for measuring beam quality in a laser eye surgery system provide a direct, quantitative quality measurement of the focused laser beam, and may be performed quickly and automatically. Using scanning mirror position information together with signals resulting from laser light reflected from the target, the laser eye surgery system may also be calibrated.

    Abstract: A system for laser ophthalmic surgery includes: a single laser source, under the operative control of a controller, configured to alternatively deliver a first treatment laser beam and a second treatment laser beam. The first treatment laser beam has a pulse energy of 10 to 500 μJ. The second pulsed laser beam has a second pulse energy of about 0.1 to 10 μJ, lower than the first treatment laser beam. An optical system focuses the first treatment laser beam to a first focal spot and directs the first focal spot in a first treatment pattern into a first intraocular target. The optical system also focuses the second treatment laser beam to a second focal spot and direct the second focal spot in a second treatment pattern into a second intraocular target. The first intraocular target and second intraocular target are different.

    Abstract: A laser eye surgery system includes a laser source, a ranging subsystem, an integrated optical subsystem, and a patient interface assembly. The laser source produces a treatment beam that includes a plurality of laser pulses. The ranging subsystem produces a source beam used to locate one or more structures of an eye. The ranging subsystem includes an optical coherence tomography (OCT) pickoff assembly that includes a first optical wedge and a second optical wedge separated from the first optical wedge. The OCT pickoff assembly is configured to divide an OCT source beam into a sample beam and a reference beam. The integrated optical subsystem is used to scan the treatment beam and the sample beam. The patient interface assembly couples the eye with the integrated optical subsystem so as to constrain the eye relative to the integrated optical subsystem.

    Abstract: A laser eye surgery system includes a laser to generate a laser beam. A topography measurement system measures corneal topography. A processor is coupled to the laser and the topography measurement system, the processor embodying instructions to measure a first corneal topography of the eye. A first curvature of the cornea is determined. A target curvature of the cornea that treats the eye is determined. A first set of incisions and a set of partial incisions in the cornea smaller than the first set of incisions are determined. The set of partial incisions is incised on the cornea by the laser beam. A second corneal topography is measured. A second curvature of the cornea is determined. The second curvature is determined to differ from the target curvature and a second set of incisions are determined. The second set of incisions is incised on the cornea.

    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.
