Abstract: Diagnostic instruments, systems and methods for performing measurements on eyes are disclosed. In one embodiment of the instrument, a left ocular is disposed in a portion of a left visual path for the left eye, the left ocular positioned to permit the left eye to view a target, a right ocular is disposed in a portion of a right visual path for the right eye, the right ocular positioned to permit the right eye to view a target. The instrument can also include a wavefront sensor disposed on a translation stage, the wavefront sensor having an optical path to an imaging sensor, the translation stage being movable to position the optical path of the wavefront sensor in alignment with the portion of the left visual path in a first state and in alignment with the portion of the right visual path in a second state. One or more light sources are optionally provided for propagating light along a least part of the left and right visual paths to illuminate the left and right eyes.

Abstract: Wavefront measuring systems and methods are disclosed which may be employed, for example, in detecting phase aberrations in a spectacle lens and in an eye. Various embodiments include disposing a modulation pattern in the path of a return beam from the spectacle lens or the eye, and imaging a diffraction pattern at a self-imaging plane relative to the modulation pattern with a detector. The diffraction pattern is analyzed and the results are used to produce a representation of the wavefront phase characteristics that describe aberrations in the lens or eye being measured. Illumination and processing techniques for improving the measurement results are disclosed. Various embodiments comprise systems adaptable to both measure aberrations in lenses in spectacles as well as in a patient's eyes.
