Abstract: An apparatus and method: project a plurality of light spots onto a cornea of an eye having a tear film disposed thereon, wherein the light spots are broadband light spots or are narrowband light spots whose bandwidth is tuned in time across a broad bandwidth; image the light spots from the cornea onto at least one two-dimensional detector array; spectrally resolve each of the plurality of imaged light spots; perform interferometry on the spectrally resolved imaged light spots to identify an anterior interface and a posterior interface of the tear film of the eye; and determine a thickness of the tear film as a distance between the anterior interface and the posterior interface.

Abstract: A method and device: pass a probe beam to the retina of an eye through a refractive region of a combined diffractive-refractive intraocular lens (IOL) which is implanted into the eye; provide light returned from the retina to a wavefront sensor which includes a detector array and images the returned light onto the detector array to produce a first set of light spots which returned from the retina through the refractive region of the combined diffractive-refractive IOL and a second set of light spots which returned from the retina through a diffractive region of the combined diffractive-refractive IOL; select a first region of the detector array which includes at least some of the first set of light spots and excludes the second set of light spots; and determines a refraction of the eye with the combined diffractive-refractive IOL implanted therein using only data from the first set of light spots.

Abstract: A system includes: a group of first light sources arranged around a central axis, the group being separated from the axis by a radial distance defining an aperture in the group; a plurality of second light sources; a detector array; and an optical system adapted to provide light from the second light sources through the aperture to a cornea of an eye, and to provide images of the first light sources and images of the second light sources from the cornea, through the aperture, to the detector array. The optical system includes a field flattener such that a shape of a surface of best focus on the detector array curves away from detector array in generally a same direction as the eye and a sclera of the eye.

Abstract: Embodiments of this invention generally relate to systems and methods for optical treatment and more particularly to non-invasive refractive treatment method based on sub wavelength particle implantation. In an embodiment, a method for optical treatment identifies an optical aberration of an eye, determines a dopant delivery device configuration in response to the optical aberration of the eye, wherein the determined dopant delivery device is configured to impose a desired correction to the eye to mitigate the identified optical aberration of the eye by applying a doping pattern to the eye so as to locally change a refractive index of the eye.

Abstract: An instrument includes: one or more scanning mirrors to receive an OCT sample beam and to scan the sample beam in two orthogonal directions; and an optical system to receive the sample beam and provide the sample beam to an eye. The optical system includes: a first lens having a first focal length, disposed along an optical path from the scanning mirror(s) to the eye at a distance from the cornea which is approximately equal to the first focal length, and a second lens disposed along the optical path between the first lens and the scanning mirror(s). The second lens receives the sample beam from the scanning mirror(s) and provides the sample beam to the first lens as a converging beam such that, as the sample beam is scanned, the sample beam passes through a pivot point located along an optical axis between the eye and the first lens.

Abstract: An optical measurement system method for measuring a characteristic of a subject's eye use a probe beam having an infrared wavelength in the infrared spectrum to measure a refraction of the subject's eye at the infrared wavelength; capture at least two different Purkinje images at two different corresponding wavelengths from at least one surface of the lens of the subject's eye; determine from the at least two different Purkinje images a value for at least one parameter of the subject's eye; use the value of the at least one parameter to determine a customized chromatic adjustment factor for the subject's eye; and correct the measured refraction of the subject's eye at the infrared wavelength with the customized chromatic adjustment factor to determine a refraction of the subject's eye at a visible wavelength in the visible spectrum.

Abstract: An optical measurement system: passes a probe light beam through a variable focal length lens to the retina of an eye, and returns light from the retina through the variable focal length lens to a wavefront sensor; adjusts the focal length of the variable focal length lens to provide a desired characteristic to at least one of: the probe light beam, and the light returned by the retina to the wavefront sensor; passes a calibration light through the variable focal length lens to the wavefront sensor while the variable focal length lens is at the adjusted focal length to ascertain the adjusted focal length; and makes a wavefront measurement of the eye from the light returned from the retina of the eye through the variable focal length lens to the wavefront sensor, and from the adjusted focal length ascertained from the calibration light received by the wavefront sensor.
