摘要： An ophthalmic apparatus for precisely positioning an optical instrument, such as a wavefront aberrometer, in three dimensions with respect to a patient's eye. The ophthalmic apparatus may include an optical instrument directed in a first direction toward a target area to receive light therefrom and a camera directed in a second direction toward the target area to receive light therefrom, the first and second directions being non-parallel. The camera may include imaging optics to form an optical image on a photodetector array using light reflected from the target area. The ophthalmic apparatus may also include a processor configured to correlate a position of the optical image on the photodetector array with the distance between the optical instrument and the target area.

摘要： A wavefront sensor is integrated with a surgical microscope for allowing a doctor to make repeated wavefront measurements of a patient's eye while the patient remains on an operating table in the surgical position. The device includes a wavefront sensor optically aligned with a surgical microscope such that their fields of view at least partially overlap. The inclusion of lightweight, compact diffractive optical components in the wavefront sensor allows the integrated device to be supported on a balancing mechanism above a patient's head during a surgical procedure. As a result, the need to reposition the device and/or the patient between measuring optical properties of the eye and performing surgical procedures on the eye is eliminated. Many surgical procedures may be improved or enhanced using the integrated device, including but not limited to cataract surgery, Conductive Keratoplasty, Lasik surgery, and corneal corrective surgery.

摘要： A system and method for determining an objective quality metric for image data collected by a wavefront aberrometer. The method may include quantifying a plurality of characteristics of the image data and calculating the objective quality metric based on the quantified characteristics of the image data. The objective quality metric can be a weighted sum of the quantified characteristics of the image data. The weightings for the weighted sum can be determined based on subjective quality metrics assigned to a set of training image data by a human expert.

摘要： An ophthalmic method for determining a relationship between aphakic ocular power and estimated effective lens position (ELP) of an intraocular lens (IOL) to be implanted in a patient's eye. The method can be used to determine an estimate of the ELP of an IOL given the aphakic ocular power of the patient's eye, for example, without measurement of the corneal curvature or axial length of the patient's eye. The estimate of ELP can then be used to determine a suitable value of optical power for the IOL to be implanted in the patient's eye.

摘要： An ophthalmic apparatus for measuring spatial distances within a patient's eye is disclosed. The apparatus can be used to measure, for example, the capsular bag depth in an aphakic eye. The spatial measurement system can direct laser light into a patient's eye so that a portion of the light is scattered by the capsular bag. The scattered light can be directed to a detector where spots can be formed corresponding to the locations on the capsular bag from which the light was scattered. The distance from the cornea to the capsular bag can be determined based, for example, at least in part on the distance between the spots formed on the detector. In some embodiments, the apparatus can include a surgical microscope and/or a wavefront aberrometer. In some embodiments, an alignment system can be used to precisely position the apparatus relative to the patient's eye. The ophthalmic apparatus can be used for variety of ophthalmic procedures, such as predicting the postoperative position of an intraocular lens (IOL) and determining appropriate optical power for the IOL.

摘要： An ophthalmic optical power measurement device can include a light source configured to direct an input beam of light into the eye of a patient. The ophthalmic optical power measurement device can also include an aperture configured to receive an output beam that consists of light from the input beam that scatters from a location on the retina of the eye and exits through the pupil of the eye. The ophthalmic optical power measurement device can also include a detector configured to receive the output beam after it has passed through the aperture. A processor can be configured to determine the size of a spot created by the output beam on the detector, and to determine the optical power of the eye based upon the size of the spot.
