Abstract: An optical coherence tomography (OCT) apparatus includes an optical source module comprising two or more selectable optical sources or an optical source configured to selectively operate in two or more source operating modes, or a combination of both, and further comprises an OCT engine coupled to the optical source module, the OCT engine comprising an OCT interferometer. The OCT apparatus still further includes a mode-switching optics module coupled to the OCT engine and comprising one or more swappable, selectable, or adjustable optical components, such that the mode-switching optics module is configured to selectively provide two or more optical configurations for the optical path between the OCT engine and an imaged object, according to two or more corresponding operating modes.

Abstract: Methods, devices, and systems for determining an orientation of a surgical tool during ophthalmic surgery are disclosed. An example method includes performing an optical imaging scan in the surgical site, using a scan pattern that intersects the surgical tool and generating a scan image from the optical imaging scan. The example method further comprises analyzing the scan image to determine a location in the scan image corresponding to where the surgical tool intersected the optical imaging scan, and determining an orientation of the surgical tool, based on the determined location.

Abstract: Systems, apparatuses, and methods of and for an ophthalmic visualization system are disclosed. An example ophthalmic visualization system may include a first lens positioned relative to a surgical microscope in a manner facilitating viewing of a central region of a retina through the surgical microscope during a surgical procedure. The first lens may be positionable in an optical path between an eye and the surgical microscope during the surgical procedure. The example ophthalmic visualization system may also include a second lens selectively positionable relative to the surgical microscope and the first lens in a manner facilitating viewing of a peripheral region of the retina of the eye during the surgical procedure. The second lens may be selectively positionable in the optical path such that the peripheral region is selectively viewable without changing the position of the first lens during the surgical procedure.
