    Abstract: Methods and apparatus are configures to measure an eye without contacting the eye with a patient interface, and these measurements are used to determine alignment and placement of the incisions when the patient interface contacts the eye. The pre-contact locations of one or more structures of the eye can be used to determine corresponding post-contact locations of the one or more optical structures of the eye when the patient interface has contacted the eye, such that the laser incisions are placed at locations that promote normal vision of the eye. The incisions are positioned in relation to the pre-contact optical structures of the eye, such as an astigmatic treatment axis, nodal points of the eye, and visual axis of the eye.

    Abstract: A laser eye surgery system used to treat vitreous bodies 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. In some embodiments, 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. In other embodiments, Purkinje imaging, Scheimpflug imaging, confocal or nonlinear optical microscopy, ultrasound, stereo imaging, fluorescence imaging, or other medical imaging technique may be used.

    Abstract: A laser surgery system includes a light source, an eye interface device, a scanning assembly, a confocal detection assembly and preferably a confocal bypass assembly. The light source generates an electromagnetic beam. The scanning assembly scans a focal point of the electromagnetic beam to different locations within the eye. An optical path propagates the electromagnetic beam from a light source to the focal point, and also propagates a portion of the electromagnetic beam reflected from the focal point location back along at least a portion of the optical path. The optical path includes an optical element associated with a confocal detection assembly that diverts a portion of the reflected electromagnetic radiation to a sensor. The sensor generates an intensity signal indicative of intensity the electromagnetic beam reflected from the focal point location. The confocal bypass assembly reversibly diverts the electromagnetic beam along a diversion optical path around the optical element.

    Abstract: A laser system calibration method and system are provided. In some methods, a calibration plate may be used to calibrate a video camera of the laser system. The video camera pixel locations may be mapped to the physical space. A xy-scan device of the laser system may be calibrated by defining control parameters for actuating components of the xy-scan device to scan a beam to a series of locations. Optionally, the beam may be scanned to a series of locations on a fluorescent plate. The video camera may be used to capture reflected light from the fluorescent plate. The xy-scan device may then be calibrated by mapping the xy-scan device control parameters to physical locations. A desired z-depth focus may be determined by defining control parameters for focusing a beam to different depths. The video camera or a confocal detector may be used to detect the scanned depths.

    Abstract: Methods and systems for performing laser-assisted surgery on an eye form a layer of bubbles in the Berger's space of the eye to increase separation between the posterior portion of the lens capsule of the eye and the anterior hyaloid surface of the eye. A laser is used to form the layer of bubbles in the Berger's space. The increased separation between the posterior portion of the lens capsule and the anterior hyaloid surface can be used to facilitate subsequent incision of the posterior portion of the lens capsule with decreased risk of compromising the anterior hyaloid surface. For example, the layer of bubbles can be formed prior to performing a capsulotomy on the posterior portion of the lens capsule.

    Abstract: An imaging system includes an eye interface device, a scanning assembly, a beam source, a free-floating mechanism, and a detection assembly. The eye interface device interfaces with an eye. The scanning assembly supports the eye interface device and scans a focal point of an electromagnetic radiation beam within the eye. The beam source generates the electromagnetic radiation beam. The free-floating mechanism supports the scanning assembly and accommodates movement of the eye and provides a variable optical path for the electronic radiation beam and a portion of the electronic radiation beam reflected from the focal point location. The variable optical path is disposed between the beam source and the scanner and has an optical path length that varies to accommodate movement of the eye. The detection assembly generates a signal indicative of intensity of a portion of the electromagnetic radiation beam reflected from the focal point location.
