    摘要： An optical measurement system: passes a probe light beam through a variable focal length lens to the retina of an eye, and returns light from the retina through the variable focal length lens to a wavefront sensor; adjusts the focal length of the variable focal length lens to provide a desired characteristic to at least one of: the probe light beam, and the light returned by the retina to the wavefront sensor; passes a calibration light through the variable focal length lens to the wavefront sensor while the variable focal length lens is at the adjusted focal length to ascertain the adjusted focal length; and makes a wavefront measurement of the eye from the light returned from the retina of the eye through the variable focal length lens to the wavefront sensor, and from the adjusted focal length ascertained from the calibration light received by the wavefront sensor.

    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： A system includes: a group of first light sources arranged around a central axis, the group being separated from the axis by a radial distance defining an aperture in the group; a plurality of second light sources; a detector array; and an optical system adapted to provide light from the second light sources through the aperture to a cornea of an eye, and to provide images of the first light sources and images of the second light sources from the cornea, through the aperture, to the detector array. The optical system includes a field flattener such that a shape of a surface of best focus on the detector array curves away from detector array in generally a same direction as the eye and a sclera of the eye.

    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.
