摘要： A method and an apparatus for extrapolating diagnostic data relating to one pupil diameter to another pupil diameter. Embodiments according to the invention are more particularly directed to extrapolating wavefront aberration data, for example, in the form of Zernike polynomial data, obtained from a smaller pupil diameter, d1, to a larger pupil diameter, d2. Data relating to the first pupil diameter d1 may be obtained in a diagnostic procedure. In the extrapolation, a conversion matrix M is utilized. The conversion matrix M can be generated from a static matrix and a dynamic matrix, the latter taking the pupil diameter d1 into consideration. Data relating the first pupil diameter d1 and wavefront aberration data can be ordered via a permutation matrix P. If necessary, Extrapolated data can be re-ordered via a transposed permutation matrix PT. The extrapolated data relating to the pupil diameter d2 can be processed to obtain an ablation profile, a shot file, or other data for a refractive vision correction treatment.

摘要： The invention relates to an apparatus and a method for determining the applicability of a treatment pattern for manipulation of a cornea of an eye using a laser. The concept of the present invention is based on the determination of an actual volumetric profile based on a set of input data and a theoretical volumetric profile which is created independently based on only the basic optical parameters. On the basis of a comparison of the determined volumetric profiles it is determined whether the actual volumetric profile is within predetermined tolerances.

摘要： A method and apparatus for remotely verifying the calibration status of a diagnostic instrument, for example, following remote installation of a software upgrade on the instrument. In one example, a method of verifying the calibration status of the instrument, includes retrieving stored raw calibration test data generated during a previously-performed calibration of the instrument, processing the raw calibration test data to generate a diagnostic reading, comparing the diagnostic reading to a known nominal reading, and based on the comparison, generating an output indicative of the calibration status of the instrument. In one example, the method is performed without contemporaneously measuring a calibration object with the instrument and therefore, without activating the measurement head or measurement optics of the instrument.

摘要： The invention relates to an apparatus, an algorithm and a method for providing a laser shot file for use in a laser. The laser may be an excimer laser. The shot file may be applied for performing a refractive laser treatment of an eye or for producing a customized contact lens or an intraocular lens. According to the invention information with respect to a desired ablation profile is provided and a first series of laser shot positions is calculated based on the desired ablation profile. A simulated ablation profile is generated using said first series of laser shot positions and using information about pulse characteristics of a single laser shot. The simulated ablation profile is compared with the desired ablation profile and residual structures are determined.

摘要： The invention is generally directed to the field of image processing, and more particularly to a method and an apparatus for determining a wavefront of an object, in particular a human eye. The invention discloses a method and an apparatus for real-time wavefront sensing of an optical system utilizing two different algorithms for detecting centroids of a centroid image as provided by a Hartmann-Shack wavefront sensor. A first algorithm detects an initial position of all centroids and a second algorithm detects incremental changes of all centroids detected by said first algorithm.

摘要： Methods and apparatus for improving vision incorporate the effects of biodynamical and biomechanical (biological) responses of the eye. The eye produces a biological response to trauma, such as a LASIK keratectomy or other necessary traumatic procedure in preparation for refractive surgery. By observing the biological response, a prospective treatment to correct higher order aberrations is adjusted to compensate for the biological effects. An improved photorefractive surgery system incorporates one or more suitable diagnostic devices that provide biological response information in such a manner that the patient need not change position from that assumed for the surgical procedure.
