摘要： A mobile communication device-based corneal topography system includes an illumination system, a mobile communication device and a corneal topography optical housing. The illumination system is configured to generate an illumination pattern and to generate reflections of the illumination pattern off a cornea of a subject, wherein the illumination system is aligned along an axis of centers of the illumination pattern. The mobile communication device includes an image sensor to capture an image of the reflected illumination pattern. The corneal topography optical housing is coupled to the illumination system and the mobile communication device, wherein the corneal topography optical housing supports and aligns the illumination system with the image sensor of the mobile communication device. The corneal topography optical housing includes an imaging system coupled to the image sensor.

A method of operating a surgical microscope may include: receiving light reflected from the surgical field at an image sensor; processing the received light to generate image data; identifying portions of the image data representative of glare; and controlling an optical element to limit the transmission of light associated with the glare. A surgical microscope may include: an image sensor configured to receive light reflected from the surgical field, a computing device, and an optical element. The computing device may be configured to: identify portions of the light received at the image sensor associated with glare and generate a control signal to limit the transmission of the light associated with the glare. The optical element may be configured to selectively limit the transmission of the light associated with the glare in response to the control signal.

摘要： A single imaging platform for making in vivo measurements of an individual's eye, where the measurements are sufficient to construct an optical model of the individual's eye. The platform includes a plenoptic opthalmic camera and an illumination module. In one configuration, the plenoptic opthalmic camera captures a plenoptic image of a corneal anterior surface of the individual's eye. In another configuration, the plenoptic opthalmic camera operates as a wavefront sensor to measure a wavefront produced by the individual's eye.

摘要： A slit lamp mounted eye imaging a slit lamp integrated, a handheld, OCT integrated, or attached to a separate chinrest-joystick assembly apparatus for producing a wide field and/or magnified views of the posterior or the anterior segments of an eye through an undilated or dilated pupil. The apparatus images sections and focal planes and utilizes an illumination system that uses one or more LEDs, shifting optical elements, flipping masks, and/or aperture stops where the light can be delivered into the optical system on optical axis or off axis from center of optical system and return imaging path from the eye, creating artifacts in different locations on the eye image. Image processing is employed to detect and eliminate artifacts and masks from images. The apparatus can be used in combination with an OCT, microscope and can be disposed in a hand-held housing for hand-held use.
