Embodiments of this invention generally relate to systems and methods for wavefront interactive refraction display and more particularly to systems and methods for capturing and displaying eye wavefront interactive refraction data based on the desired refractive state of the patient's eye.

Wavefront interactive refraction display

An enhanced dynamic range wavefront sensing system includes a light source disposed on a first side of an optically transmissive device, a wavefront sensor disposed on a second side of an optically transmissive device, a relay imaging system disposed between the optically transmissive device and the wavefront sensor, and means for adjusting a distance between the light source and the optically transmissive device. Beneficially, the relay imaging system includes a range-limiting aperture to insure that the wavefront sensor never goes out of range so that a feedback system can be employed to move the light source one focal length away from the optically transmissive device.

Method and system for sensing and analyzing a wavefront of an optically transmissive system

A method for computing the visual performance of a human or animal subject based on objective measurements of visual refraction, including higher order aberrations, includes measuring wavefront aberrations of a subject ocular pupil, computing a point-spread-function from the measured pupil aberration, providing a test image, and convolving the test image with the point-spread-function. A simulated image may be produced from the convolution result of the test image with the point-spread-function. One or more specific terms of the point-spread-function may be subtracted therefrom prior to the convolving step to simulate an effect of a correcting means, such as spectacles lenses, contact lenses, or laser surgery. A best correction for a given subject may be determined by adjusting the terms that are subtracted to optimize the resultant image.

Method for computing visual performance from objective ocular aberration measurements

A Shack-Hartmann wavefront sensor having an aperture which is smaller than the size of an object being measured is used to measure the wavefront for the entire object. The wavefront sensor and the object are translated relative to one another to measure the wavefronts at a plurality of subregions of the object. The measured wavefronts are then stitched together to form a wavefront of the object. The subregions may overlap in at least one dimensions. A reference surface may be provided to calibrate the wavefront sensor.

Apparatus and method for evaluating a target larger than a measuring aperture of a sensor

An apparatus and method for characterizing a pulsed energy beam with a two-dimensional wavefront sensor. The data acquisition is synchronized with the output of the beam from the pulsed source, so that a beam characterization, including phase, can be determined in a single pulse.
