Abstract: 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.

Abstract: An optical measurement system and apparatus for carrying out cataract diagnostics in an eye of a patient includes a Corneal Topography Subsystem, a wavefront aberrometer subsystem, and an eye structure imaging subsystem, wherein the subsystems have a shared optical axis, and each subsystem is operatively coupled to the others via a controller. The eye structure imaging subsystem is preferably a fourierdomain optical coherence tomographer, and more preferably, a swept source OCT.

Abstract: An optical coherence tomography (OCT) system includes: a light source; a multi-focal delay line; and a light detector. The multi-focal delay line includes: a positive lens; and an optical switch configured to: receive a light from the light source; selectively direct the sample light to the positive lens via a selected one of a plurality of light interfaces each located a different distance from the focal plane of the positive lens; and direct the sample light to an object to be measured. The light detector is configured to receive return light returned from the object to be measured in response to the sample light, and to receive a reference light produced from the light from the light source, and in response thereto to detect at least one interference signal. An associated OCT method may be performed with the OCT system.

Abstract: 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.
