摘要： Devices, systems, and methods that facilitate optical analysis, particularly for the diagnosis and treatment of refractive errors of the eye. Embodiments of the invention may facilitate the use of multi-modal diagnostic instruments and instrument systems, making it easier to acquire and fuse data from different measurements of the eye. For example, wavefront aberrometry may be fused with corneal topography, optical coherence topography and wavefront, optical coherence topography and topography, pachymetry and wavefront, etc. While some of these different optical datasets may be obtained simultaneously, it is often difficult and/or disadvantageous to attempt to acquire the images or other data at exactly the same time. Advantageously, both patient movement between measurements (and/or during a measurement sequence) can be identified, as well as changes in the eye itself (including those induced by the measurement, such as changes in the size of the pupil, changes in pupil location, etc.).

摘要： A system for mapping a three-dimensional structure includes a projecting optical system adapted to project light onto an object, a correction system adapted to compensate the light for at least one aberration in the object, an imaging system adapted to collect light scattered by the object and a wavefront sensor adapted to receive the light collected by the imaging system and to sense a wavefront of the received light. For highly aberrated structures, a number of wavefront measurements are made which are valid over different portions of the structure, and the valid wavefront data is stitched together to yield a characterization of the total structure.

摘要： A method and associated system improve accuracy in objective refraction measurements by including the measured distance between the photoreceptors of a subjects eye and the scattering location of light during the objective refraction measurements. Chromatic aberrations in the objective measurements are also compensated. The distance between the photoreceptors and the scattering location may be determined by adjusting a distance between a rotating speckled light pattern and an eye until the speckled light pattern appears to be stationary, or by employing a Scheiner disk.

摘要： A phase diversity wavefront sensor includes an optical system including at least one optical element for receiving a light beam; a diffractive optical element having a diffractive pattern defining a filter function, the diffractive optical element being arranged to produce, in conjunction with the optical system, images from the light beam associated with at least two diffraction orders; and a detector for detecting the images and outputting image data corresponding to the detected images. In one embodiment, the optical system, diffractive optical element, and detector are arranged to provide telecentric, pupil plane images of the light beam. A processor receives the image data from the detector, and executes a Gerchberg-Saxton phase retrieval algorithm to measure the wavefront of the light beam.

摘要： A system for determining a surface shape of a test object includes a pattern having a plurality of first elements dispose about a central axis and defining an aperture containing the central axis. The first elements includes a plurality of common elements having a common form and a reference element having a reference form that is different than the common form. The system further comprises a detector array and an optical system. The optical system is adapted to provide an image of the first elements when light reflects off a surface of a test object, passes through the aperture, and is received by the detector array. The reference form may be configured to facilitate an association between the common elements and the spot images of the common elements.

摘要： Improved devices, systems, and methods for planning cataract surgery on an eye of a patient incorporate results of prior corrective surgeries into a planned cataract surgery of a particular patient by driving an effective surgery vector function based on data from the prior corrective surgeries. The exemplary effective surgery vector employs an influence matrix which may allow improved refractive corrections to be generated so as to increase the overall efficacy of a cataract surgery by specifying one or more parameters of an intraocular lens (IOL) to be implanted during the cataract surgery.

摘要： Devices, systems, and methods that facilitate optical analysis, particularly for the diagnosis and treatment of refractive errors of the eye. An optical diagnostic method for an eye includes obtaining a sequence of aberration measurements of the eye, identifying an outlier aberration measurement of the sequence of aberration measurements, and excluding the outlier aberration measurement from the sequence of aberration measurements to produce a qualified sequence of aberration measurements. The sequence of aberrations measurements can be obtained by using a wavefront sensor. An optical correction for the eye can be formulated in response to the qualified sequence of aberration measurements.
