A system and method for measuring a characteristic of an eye of a subject receive data pertaining to the subject; assign the subject to an assigned age category based on the data pertaining to the subject; adjust a brightness level of a fixation target according to the assigned age category for the subject; provide the fixation target for a subject to view; and objectively measure at least one characteristic of the eye of the subject while the subject views the fixation target at the adjusted brightness level.


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.

Wavefront | Date: 2015-04-23

This invention concerns apparatus and a method for authenticating a subject using their eye as an identifying biometric, in particular the shape of their cornea. The apparatus comprises an image projection device to generate and project an image of a pattern, made up of plural discrete points, onto at least a part of the cornea of an eye of the person. An image capture device to capture an image of the pattern of plural discrete points, after reflection in at least a part of the cornea of an eye of the person. And, a computer processor to extract a data set defining the locations of the discrete points in the captured image. The method comprises capturing an image of an illuminated pattern, made up of plural discrete points, after reflection in at least a part of the cornea of an eye of the subject. Comparing the locations of the discrete points in the pattern of the captured image against the locations of the discrete points in the pattern of a reference image. And, authenticating the identity of the subject depending on the similarity of comparison. In a further aspect the invention is software for performing the method.
