Whole eye optical coherence tomography (OCT) imaging systems and related methods are disclosed. According to an aspect, an OCT imaging system includes a source having an associated source arm path. Further, the OCT imaging system includes a reference arm coupled to the source arm. Further, the OCT imaging system includes a sample arm having an associated sample arm path and coupled to the source arm. The sample arm includes at least one optical component configured to simultaneously scan both an anterior and posterior portion of an eye of a subject.

Systems, devices, and methods are disclosed which may be used to detect and determine the extent of brain trauma, mental impairment, physical disability, or other brain dysfunction by tracking one or more ocular responses.

Systems and methods are disclosed herein for detecting eye alignment during retinal imaging. In an embodiment, the system receives an infrared stream from an imaging device, the infrared stream showing characteristics of an eye of a patient. The system determines, based on the infrared stream, that the eye is improperly aligned at a first time, and outputs sensory feedback indicative of the improper alignment. The system detects, based on the infrared stream at a second time later than the first time, that the eye is properly aligned, and receives an image of a retina of the properly aligned eye from the imaging device.

A method, a, controller, a non-transitory computer readable storage medium encoded with instructions; each of which control an apparatus to produce multiple images of an area of an eye in parallel. Selecting one of the images for estimating a change in position of the area to be used for tracking the area of the eye being imaged.

Apparatus and methods for eye tracking using an optical coherence tomography (OCT) device are disclosed. Such eye tracking may be performed by using information about the shape of the cornea and the corneal apex or using the iris/pupil border obtained using the OCT device.

An ophthalmic system may be configured to image an eye of a patient. The system may include a housing, a lens, and a control assembly. The housing may extend along a central axis and between a proximal portion and a distal portion. The lens with a lens axis may be disposed in the distal portion of the housing. The control assembly may be disposed in the proximal portion of the housing. The control assembly may include and operatively connect a camera assembly having a camera axis and a lighting assembly. The lighting assembly may include a non-visible light source configured to focus the camera assembly and a visible light source configured to capture an image of the eye. The lens axis and the camera axis may be along the central axis of the housing.

A multispectral or hyperspectral ocular surface evaluating device is disclosed, comprising an illumination projector, which comprises a broadband illumination source panel and a polarizing structure to illuminate an ocular surface and adjacent structures of an eye and project a pattern on the ocular surface; an imaging system to form images; a detection system to record the images with a plurality of spectral channels in visible and near infrared spectra; and a computer to display and analyze the images. Also disclosed is a method of evaluating ocular surface health using a multispectral or hyperspectral ocular surface evaluating device, which comprises illuminating an ocular surface and adjacent structures of an eye with polarized light from an illumination projector; forming images with the imaging system; recording images formed on the detection system; digitally processing the recorded images; and analyzing the recorded images to evaluate ocular surface health with the computer.

In order to take advantage of the real time nature of intra-operative refraction or wavefront aberrometry, and visually make the history of the measurements apparent to a surgeon, a histogram of frequency vs IOL results calculated from an IOL formula is computed and IOL suggestions being accumulated are displayed in a histogram. One embodiment is a means to present to a surgeon a histogram of intra-operative refractions. Another embodiment is to automatically and intra-operatively detect the aphakic phase of a cataract surgery to display a histogram of a recommended IOL power.

A system for multi-scale closed-loop eye tracking to compensate for translation and rotation motion while imaging in vivo a surface area of an internal structure of an eye of a subject includes a narrow field imaging device optically coupled to an optical path to receive light reflected from the surface area of the structure of the eye. A wide field camera is optically coupled to the optical path by a beam splitter disposed in the optical path. A tracking mirror is disposed in the optical path between the beam splitter and the structure of the eye. A control process algorithm actively compensates substantially in real time for both translational and rotational movements of the eye. A system where a torsional correction device causes a rotating movement of a subject's head and a method for multi-scale closed-loop eye tracking are also described.

The present disclosure provides methods, devices, and systems for automated measured correction of the eyes and provision of sunglasses and eyeglasses for individuals, including individuals with a visual acuity of 20/20 or better. Methods, devices and systems for remote measurement of refraction by an examiner away from the measurement system are also disclosed.
