Abstract: An adapter (10) for pivoting a lens relative to an image sensor in a camera has lens-side and housing-side supporting rings (20, 30) that slide relative to one another by cylindrically curved sliding surfaces (22, 32) facing one another. A virtual cylinder axis (Z) of the sliding surfaces (22, 32) lies in a plane of the image sensor. A transmission lever (50) with first and second lever arms (51,52) is mounted on the lens-side supporting ring (20) and pivots about an axis (H) parallel to the virtual cylinder axis (Z). The first lever arm (51) extends in a circumferential direction on the lens side of the lever axis (H) and is coupled to an adjusting ring (42) mounted rotatably on the lens-side supporting ring (20). The second lever arm (52) extends axially of the housing side and is supported on an anchor (70) fixed to the housing-side supporting ring (30).

Abstract: Apparatuses and methods for improving aberration determination capabilities, providing corrective prescription verification, and allowing binocular vision correction in ophthalmic wavefront measuring devices. (1) Improved aberration determination capabilities are achieved through input beam modification which includes sensing an image in a wavefront emanating from an eye in response to an input beam with a sensor and then modifying the input beam with an adaptive optical device based on the sensed information. (2) Corrective prescription verification includes modifying an image with an adaptive optical element to produce a corrected image at the patients eye. (3) Binocular vision correction for a pair of eyes includes measuring the aberrations of one eye with a first ophthalmic wavefront measuring device and measuring the aberration produced by the other eye with a second ophthalmic wavefront measuring device substantially simultaneously.

Abstract: Defocus and astigmatism compensation methods and apparatuses for use in an aberration measurement system. The apparatuses including reflectors for altering the optical distance between a pair of lenses passing a wavefront without changing the physical distance between the lenses, thereby compensating for defocus in the wavefront; and cylindrical mirrors for adding and removing curvature from a curved wavefront, thereby compensating for astigmatism in the wavefront. The methods including passing a wavefront having defocus through a first lens on a first path, reflecting the wavefront from the first path to a second path, reflecting the wavefront from the second path to a third path, and passing the wavefront through a second lens as a defocus compensated wavefront; and passing a wavefront through first and second cylindrical lens, and orienting the first and second cylindrical lenses with respect to the wavefront and to one another to compensate for astigmatism in the wavefront.

Abstract: Apparatus and method for subjectively refining a corrective prescription based on feedback from a patient. Subjective refinement of a corrective prescription is accomplished by measuring aberrations of a wavefront emanating from the eye, computing a proposed corrective prescription based on the measured aberrations presenting to the patient an image reflecting the proposed corrective prescription, and varying the proposed corrective prescription based on feedback from the patient through an input device coupled to the processor to obtain the preferred corrective prescription.
