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: Systems and methods for call detail record (CDR) analysis to determine a risk score for a call and identify fraudulent activity and for fraud detection in Interactive Voice Response (IVR) systems. An example method may store information extracted from received calls. Queries of the stored information may be performed to select data using keys, wherein each key relates to one of the received calls, and wherein the queries are parallelized. The selected data may be transformed into feature vectors, wherein each feature vector relates to one of the received calls and includes a velocity feature and at least one of a behavior feature or a reputation feature. A risk score for the call may be generated during the call based on the feature vectors.

Abstract: A method of altering a refractive property of a crosslinked acrylic polymer material by irradiating the material with a high energy pulsed laser beam to change its refractive index. The method is used to alter the refractive property, and hence the optical power, of an implantable intraocular lens after implantation in the patient's eye. In some examples, the wavelength of the laser beam is in the far red and near IR range and the light is absorbed by the crosslinked acrylic polymer via two-photon absorption at high laser pulse energy. The method also includes designing laser beam scan patterns that compensate for effects of multiphone absorption such as a shift in the depth of the laser pulse absorption location, and compensate for effects caused by high laser pulse energy such as thermal lensing. The method can be used to form a Fresnel lens in the optical zone.

Abstract: The amount of energy to provide optical breakdown can be determined based on mapped optical breakdown thresholds of the treatment volume, and the laser energy can be adjusted in response to the mapped breakdown thresholds. The mapping of threshold energies can be combined with depth and lateral calibration in order to determine the location of optical breakdown along the laser beam path for an amount of energy determined based on the mapping. The mapping can be used with look up tables to determine mapped locations from one reference system to another reference system.

Abstract: A fiducial is generated on an internal anatomical structure of the eye of a patient with a surgical laser. A toric artificial intraocular lens (IOL) is positioned so that a marker of the toric IOL is in a predetermined positional relationship relative to the fiducial. This positioning aligns the toric IOL with the astigmatic or other axis of the eye. The toric IOL is then implanted in the eye of the patient with high accuracy.

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.

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.
