Abstract: In certain embodiments, an ophthalmic system images an eye region comprising at least one eye. The system includes a camera system and a computer. The camera system includes cameras that yield image portions of the eye region. Each camera is located at a position relative to the eye region and yields an image portion. The computer receives the image portions from the camera system. A first image portion is provided by a first camera, and a second image portion is provided by a second camera. The computer identifies identify target pixels of the first image portion, where the target pixels image a location of the eye region; determines image information of correction pixels of the second image portion, where the correction pixels image the same location of the eye region; and corrects the target pixels using the identified image information.

Abstract: According to certain embodiments, an ophthalmic system for providing an image of an eye includes a camera system and a computer. The camera system includes stereoscopic cameras that provide image data for images of the eye. The computer: receives the image data from the camera system; accesses overlay data for an overlay for the image of the eye; aligns the overlay data and the image data; digitally combines the overlay data and the image data to yield combined image data for an image with the overlay; and provides the combined image data to a display device to display the image with the overlay in three dimensions.

Abstract: In certain embodiments, an ophthalmic system tracks movement of an eye region and includes a camera system and a computer. The camera system has cameras that yield image portions of the eye region, where each camera images at least a part of the eye region. The camera system has a system axis and system field of view. The eye region includes one or both eyes, and each eye has an eye center and eye axis. The computer receives the image portions from the camera system and tracks movement of at least one eye according to the image portions.
