Abstract: A system and method for a reconfigurable surgical microscope is disclosed. The reconfigurable microscope includes an eyepiece; a relay lens system optically coupled to the eyepiece; a zoom lens system optically coupled to the eyepiece and the relay lens system; an illumination unit; and an objective lens capable of being repositioned between a first objective lens position and a second objective lens position, the first objective lens position comprising a slot located between the zoom lens system and the illumination unit and the second objective lens position comprising a slot located such that the illumination unit is located between the second objective lens position and the zoom lens system.

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: The present disclosure provides a system and method for cutting a flap in laser ophthalmic surgery using polarization sensitive optical coherence tomography (PS-OCT). The system includes a PS-OCT system, a femtosecond laser, control device, and processor. The PS-OCT system includes a PS-OCT source, a polarization component, a reference reflector, a beam splitter, a wave plate, and a detector. The processor receives data relating to an interference pattern of a reflected PS-OCT beam, received at the detector, determines a relative fiber orientation of the sample, determines whether a photodisruption pattern generated by the femtosecond laser to cut the flap should be adjusted horizontally or vertically, based on the relative fiber orientation, and may generate a control signal to adjust the photodisruption pattern generated by the femtosecond laser. The disclosure further provides a method for cutting a flap on an eye using PS-OCT.
