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： A corneal topographer includes: a flat panel display configured to display a light pattern and to project the light pattern onto a cornea of an eye disposed on a first side of the flat panel display; an optical system disposed on a second side of the flat panel display, the optical system being configured to receive and process reflected light from the cornea that passes through the flat panel display from the cornea to the optical system; a camera configured to receive the processed reflected light from the optical system and to capture therefrom a reflected light pattern from the cornea produced in response to the projected light pattern; and one or more processors configured to execute an algorithm to compare the projected light pattern to the reflected light pattern from the cornea, and to produce a topographic map of the cornea based on a result of the comparison.

摘要： A system includes a model eye and an optical measurement instrument, which includes: a corneal topography subsystem; a wavefront sensor subsystem; and an eye structure imaging subsystem. The subsystems may have a common fixation axis, and be operatively coupled to each other via a controller. The optical measurement instrument may perform measurements of the model eye to verify correct operation of the optical measurement instrument for measuring one or more characteristics of a subject's eye. The model eye may include an optically transmissive structure having a front curved surface and an opposite rear planar surface, and a material structure provided at the rear planar surface of the optically transmissive structure and having a characteristic to cause a speckle pattern of a portion of a coherent light beam that is directed back out the front curved surface of the optically transmissive structure to have a bright-to-dark ratio of less than 2:1.

摘要： Systems and methods for modifying an eye including a light source with light elements, a photodetector producing a signal representing images of the light elements and corresponding to locations on an ocular surface, an optical system directing light from the light elements reflected by the ocular surface onto the photodetector, a memory including code for processing the signal, and a processor for executing the code and outputting shape data for use in calculating a treatment plan for the eye. The code includes instructions for determining the shape data based on a combination of zonal reconstruction and polynomial fitting using the plurality of images.

摘要： A system for predicting optical power for an intraocular lens based upon measured biometric parameters in a patient's eye includes: a biometric reader capable of measuring one or more biometric parameters of the patient's eye and obtaining at least one value for at least one of the one or more biometric parameters, and further measuring a representation of a corneal topography of the patient's eye; a processor; and a computer readable medium coupled to the processor and having stored thereon a program that upon execution causes the processor to: receive the at least one value; obtain a corneal spherical aberration (SA) based upon the representation of the corneal topography; and calculate an optimized optical power to obtain a desired postoperative condition by applying the received at least one value and the obtained corneal spherical aberration to a modified regression.
