    Abstract: Devices, systems, and methods for visualizing moving tissue with strobed light are provided. A surgical system includes a surgical device configured to operate on anatomy at a first frequency such that the anatomy moves at the first frequency when the surgical device is in contact therewith; and a light source configured to provide pulses of light at a second frequency to illuminate the moving anatomy; wherein the second frequency is different than the first frequency. A method of treating an ophthalmic condition includes operating a surgical device at a first frequency such that anatomy moves at the first frequency when the surgical device is contacted therewith; and controlling a light source to provide pulses of light at a second frequency to illuminate the moving anatomy; wherein the second frequency is different than the first frequency. An ophthalmic surgical system includes a cutting probe, a strobed light source, and a computing device.

    Abstract: An ophthalmic surgical microscope includes a beam coupler positioned along an optical path of the surgical microscope between a first eyepiece and magnifying/focusing optics, the beam coupler operable to direct the OCT imaging beam along a first portion of the optical path of the surgical microscope between the beam coupler and a patient's eye (an OCT image being generated based on a reflected portion of the OCT imaging beam). The surgical microscope additionally includes a real-time data projection unit operable to project the OCT image generated by the OCT system and a beam splitter positioned along the optical path of the surgical microscope between a second eyepiece and the magnifying/focusing optics. The beam splitter is operable to direct the projected OCT image along a second portion of the optical path of the surgical microscope between the beam splitter and the second eyepiece such that the projected OCT image is viewable through the second eyepiece.

    Abstract: A vitrectomy surgical system is disclosed herein. The surgical system includes a vitrectomy probe having a cutting portion comprising an inner cutting tube, an outer cutting tube, and an outer port. The inner cutting tube is movable relative to the outer cutting tube to cut vitreous humor during a vitrectomy procedure. The surgical system further includes a motor configured to move the inner cutting tube relative to the outer cutting tube and one or more pressure sensors coupled to the vitrectomy probe to measure a pressure proximate to a distal portion of the vitrectomy probe and provide pressure feedback. Related systems and methods are also included.
