    Abstract: PROBLEM TO BE SOLVED: To provide a method and an apparatus for objectively measuring aberration of an optical system by wavefront analysis. SOLUTION: A method for enhancing vision of an eye includes a laser supply device having a laser beam for ablating corneal material from the cornea of the eye. Measurements are made to determine an optical path difference between a plane wave and a wavefront emanating from the retina of the eye for a location at a surface of the cornea. An optical correction is provided to the laser delivery system for the location based on the optical path difference and refractive indices of media through which the wavefront passes. The optical correction includes dividing the optical path difference by a difference between an index of refraction of corneal material and an index of refraction of air. The laser beam is directed to the location on the surface of the cornea and corneal material ablated at the location in response to the optical correction to cause the wavefront to approximate the shape of the plane wave at that location.

    Abstract: PROBLEM TO BE SOLVED: To provide a zooming mechanism for an eye tracking system. SOLUTION: The zooming mechanism 30 includes a pyramidal prism 31 having a plurality of reflecting small faces 32 or transmissive small surfaces crossing at an apex. Incident light beams 35 sent toward the respective small surfaces 32 of the prism 31 are reflected or refracted on a plane nearly vertical to an optical axis 34 to form a plurality of optical spots disposed around the optical axis 34. The prism 31 can make translation along the optical axis 34 among a plurality of axial direction positions for changing intervals between the optical spots substantially without varying its size. The optical spots are desirably sent toward a boundary regulated by the two adjacent surfaces of an eye having different reflectances. Reflected energy is detected from each of a plurality of positions to adjust the size of a pattern formed by the optical spots substantially without varying the diameters of the individual spots.

    Abstract: The invention provides a zooming mechanism for use in an eye tracking system (100) includes a pyramidal prism that has either a plurality of reflective facets or of transmissive facets meeting at an apex. An incident light beam (35,45) directed onto each facet of the prism is reflected/refracted onto a planar surface substantially normal to the optical axis (34,44), to form a plurality of light spots (21,22,23,24) arrayed about an optical axis. The prism is translatable along the optical axis between axial positions for altering a spacing of the light spots without substantially changing their size. Preferably the spots are directed onto a boundary defined by two adjoining surfaces of the eye (10) having different coefficients of reflection. Reflected energy from each of the plurality of positions is detected, and a size of a pattern (39,49) formed by the light spots is adjustable without substantially changing a diameter of the individual light spots.

    Abstract: A system and method for objective measurement and correction of focusing optical systems comprising optics disposed in the path of the beam (18) which directs the beam through the focusing optical system, e.g., and eye (120) and focuses the beam at its rear portion (122). The beam is diffusely reflected back and a wavefront analyzer (26) is disposed in the path of the wavefront projected from the optics and calculates the distortions as an estimate of aberrations of the focusing optical system.

    Abstract: An apparatus for determining aberrations of an eye includes a patient head rest allowing for positioning adjustment. The patient head rest is operable with an optical table having a base. The base includes a probe beam generating apparatus, probe beam directing optics which itself comprises a beam splitter; a mirror; and a lens. The probe beam directing optics is capable of directing a probe beam toward an eye of a patient positioned on the patient head rest. Video image components are provided and comprise a light source, a mirror; and a video camera. The video image components are capable of generating an image of an eye of a patient positioned on the patient head rest. Eye fixation components generate a target that the eye of a patient positioned on the patient head rest can view. The eye fixation components comprise a fixation target, a light source, a lens, and a mirror. Wavefront directing and analyzing components measure a wavefront emanating from the eye of a patient positioned on the patient head rest and determine aberrations of the eye that range from at least about + or - 1 diopters to at least about + or - 6 diopters. The wavefront directing and analyzing components include a lens; a mirror, a microlens array, a camera, and a data processor.
