摘要： An apparatus to treat a patient comprises a laser beam, a measurement module, a scanner and a curved patient interface lens. The curved patient interface is measured with a pattern so as to determine a plurality of distances of the curved surface at a plurality of measurement locations. The measurement pattern may comprise the plurality of measurement locations distributed about a central measurement axis corresponding to the laser treatment axis. The plurality of measurement locations of the curved surface may correspond to a portion of a planned treatment profile, such that the measured distances correspond to alignment of the planned treatment. The plurality of distances can be used to determine an apex of the curved surface of the patient interface and to align the laser treatment axis with the apex of the curved surface.

摘要： Embodiments of the invention provide methods and systems for analyzing the ophthalmic anatomy of a patient posterior to the cornea. The method may include scanning a focus of a femtosecond laser beam along a path within the patient's eye. A portion of the path may be disposed posterior to the patient's cornea. The method may also include acquiring a first reflectance image and a second reflectance image associated with the focus disposed respectively at a first location of the path and a second location of the path. The method may further include determining the presence or absence of an ophthalmic anatomical feature of the eye based on a comparison between the first reflectance image and the second reflectance image.

摘要： Methods of photoaltering a region of a material using a pulsed laser beam. The method includes scanning the pulsed laser beam in a first portion of the region with a first pattern, scanning the pulsed laser beam in a second portion of the region with a second pattern, and separating a flap of the material at the region. The system includes a laser, a controller selecting at least first and second patterns, and a scanner operable in response to the controller. The first pattern has a first maximum acceleration associated with the second portion, and the second pattern has a second maximum acceleration associated with the second portion. The second maximum acceleration is less than the first maximum acceleration. The scanner scans the pulsed laser beam from the laser in the first portion with the first pattern and in the second portion with the second pattern.

摘要： Systems and methods for locating the center of a lens in the eye are provided. These systems and methods can be used to improve the effectiveness of a wide variety of different ophthalmic procedures. In one embodiment, a system and method is provided for determining the center of eye lens by illuminating the eye with a set of light sources, and measuring the resulting first image of the light sources reflected from an anterior surface of the lens and the resulting second image of the light sources reflected from a posterior surface of the lens. The location of the center of the lens of the eye is then determined using the measurements. In one embodiment, the center of the lens is determined by interpolating between the measures of the images. Such a determination provides an accurate location of the geometric center of the lens.

摘要： Embodiments of this invention relate to systems and methods for automatic depth (or Z) detection before, during, or after laser-assisted ophthalmic surgery. When performing ophthalmic laser surgery, the operator (or surgeon) needs to make accurate and precise incisions using the laser beam. With the automatic depth detection systems and methods, the same laser used for the surgical procedure may be used for depth measurement of the surgical incisions. The surgical laser system may include a laser delivery system for delivering a pulsed laser beam to photoalter an eye, a mirror to transmit at least a portion of reflected light of the pulsed laser beam, a lens positioned to focus the transmitted reflected lighted on to a detector, (such as a CCD), and a depth encoder configured to automatically detect depth according to one or more of color, intensity, or shape of the focused spot on the CCD.
