    摘要: A laser eye surgery system focuses light along a beam path to a focal point having a location within a lens of the eye. The refractive index of the lens is determined in response to the location. The lens comprises a surface adjacent a second material having a second refractive index. The beam path extends a distance from the surface to the focal point. The index is determined in response to the distances from the surface to the targeted focal point and from the surface to the actual focal point, which corresponds to a location of a peak intensity of an optical interference signal of the focused light within the lens. The determined refractive index is mapped to a region in the lens, and may be used to generate a gradient index profile of the lens to more accurately place laser beam pulses for incisions.

    摘要: A system for ophthalmic surgery includes a laser source configured to deliver an ultraviolet laser beam comprising laser pulses having a wavelength between 320 nm and 370 nm to photodecompose one or more intraocular targets within the eye with chromophore absorbance. The pulse energy, the pulse duration, and the focal spot are such that an irradiance at the focal spot is sufficient to photodecompose the one or more intraocular targets without exceeding a threshold of formation of a plasma and an associated cavitation event. An optical system operatively coupled to the laser source and configured to focus the ultraviolet laser beam to a focal spot and direct the focal spot in a pattern into the one or more intraocular targets. The optical system focuses the laser beam at a numerical aperture that provides for the focal spot to be scanned over a scan range of 6 mm to 10 mm.

    摘要: An OCT system for imaging multiple depth positions includes a light source, a sample arm and two or more reference arms. The sample arm propagates light to the object and directs object return light having a first return light beam from a first position and a second return light beam from a second position, the second return light having a dispersion level higher than the first return light beam by a dispersion difference amount. The first and second reference arms produce light beams having substantially the same dispersion as the first and second return light beams, respectively. The optical pathway combines all of the object return light and the reference light beams. An OCT detector measures the resulting interferogram. Imaging information is obtained for both the first position and the second position based on the dispersion difference amount.

    摘要: 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.

    摘要: Method and apparatus for performing a laser-assisted posterior capsulotomy and for performing laser eye surgery on an eye having a penetrated cornea are provided. A method for performing a posterior capsulotomy includes injecting fluid between the lens posterior capsule and the anterior hyaloids membrane to separate the lens posterior capsule and the anterior hyaloids membrane. With the lens posterior capsule separated from the anterior hyaloids membrane, a posterior capsulotomy is performed on the lens posterior capsule by using a laser to incise the lens posterior capsule.

    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.
