Systems and methods are disclosed for performing ophthalmic optical coherence tomography with multiple resolutions. In some embodiments, a system comprises a light source, an output lens, and a set of optical components between the light source and the output lens, the set of optical components comprising an afocal zoom telescope. The set of optical components is adapted to provide imaging both at a first field of view with a first resolution and at a second field of view with a second resolution, wherein the first field of view is wider than the second field of view and the second resolution is higher than the first resolution. A method of performing ophthalmic optical coherence tomography with multiple resolutions may be performed using one or more of the systems described herein.

Ophthalmic optical coherence tomography with multiple resolutions

An adapter system for displaying and recording stereoscopic images from a single lens optic device and methods of producing stereoscopic images using such an adapter are provided herein. The adapter system utilizes an active stereoscopic shutter mounted along the optical path of the single lens optic device, such as, for example, a microscope or an endoscope, to provide a stereoscopic image to a video or still camera mounted along the same optical path.

Stereoscopic optics

An ophthalmic apparatus for precisely positioning an optical instrument, such as a wavefront aberrometer, in three dimensions with respect to a patient's eye. The ophthalmic apparatus may include an optical instrument directed in a first direction toward a target area to receive light therefrom and a camera directed in a second direction toward the target area to receive light therefrom, the first and second directions being non-parallel. The camera may include imaging optics to form an optical image on a photodetector array using light reflected from the target area. The ophthalmic apparatus may also include a processor configured to correlate a position of the optical image on the photodetector array with the distance between the optical instrument and the target area.

Optical instrument alignment system

A relay optic adapter system for imaging stereoscopic images with a single lens optic device and methods of producing stereoscopic images using such a relay optic adapter are provided herein. The relay optic adapter system utilizes an active stereoscopic shutter mounted along the optical path of the single lens optic device, such as, for example, a still or video camera, to provide a stereoscopic image to imaging plane of the device.

Stereoscopic relay optics

An ophthalmic optical power measurement device can include a light source configured to direct an input beam of light into the eye of a patient. The ophthalmic optical power measurement device can also include an aperture configured to receive an output beam that consists of light from the input beam that scatters from a location on the retina of the eye and exits through the pupil of the eye. The ophthalmic optical power measurement device can also include a detector configured to receive the output beam after it has passed through the aperture. A processor can be configured to determine the size of a spot created by the output beam on the detector, and to determine the optical power of the eye based upon the size of the spot.

Geometric optical power measurement device

An ophthalmic system for use in performing angular measurements in relation to a patient's eye. The ophthalmic system can include an optical angular measurement device that can provide angular indicia by, for example, projecting an image of an angular measurement reticle onto a patient's eye or by superimposing an image of an angular measurement reticle onto an image of the patient's eye. The ophthalmic system can include an optical refractive power measurement device for providing desired angular orientations for ocular implants or for incisions. The ophthalmic system can be used, for example, to align a toric intraocular lens to a desired angular orientation.

Optical angular measurement system for ophthalmic applications and method for positioning of a toric intraocular lens with increased accuracy

An ophthalmic apparatus for measuring spatial distances within a patient's eye is disclosed. The apparatus can be used to measure, for example, the capsular bag depth in an aphakic eye. The spatial measurement system can direct laser light into a patient's eye so that a portion of the light is scattered by the capsular bag. The scattered light can be directed to a detector where spots can be formed corresponding to the locations on the capsular bag from which the light was scattered. The distance from the cornea to the capsular bag can be determined based, for example, at least in part on the distance between the spots formed on the detector. In some embodiments, the apparatus can include a surgical microscope and/or a wavefront aberrometer. In some embodiments, an alignment system can be used to precisely position the apparatus relative to the patient's eye. The ophthalmic apparatus can be used for variety of ophthalmic procedures, such as predicting the postoperative position of an intraocular lens (IOL) and determining appropriate optical power for the IOL.

Ophthalmic surgery measurement system

Objective lenses for endoscopes are made substantially of sapphire. The high refractive index of sapphire results in optical components with shallower curvatures, leading to smaller geometric aberrations, and consequently, fewer components are required to correct for these aberrations. Chromatic aberrations are less severe because of sapphire's low dispersion. The objectives may be either of the landscape or retrofocus type, and are compact with moderate field of view, low f-number, and less distortion than most conventional designs.
