Abstract: A method and system for extracting the zoom level of a microscope is disclosed. The method includes capturing a reference image; recording a first zoom level corresponding to a first magnification at which the reference image is captured; capturing a second image; determining a second zoom level by comparing the second image and the reference image, the second zoom level corresponding to a second magnification at which the second image is captured; and recording the second zoom level at a location accessible by a microscope application.

Abstract: A device for removing a tissue from an eye of a patient is disclosed, comprising a housing, a cutter, and an actuator. The cutter comprises an outer cutting tube coupled to the housing, an outer port formed in the outer cutting tube, an inner cutting tube slidable along the longitudinal axis within the outer cutting tube between a retracted position proximal to the outer port and an extended position distal to the outer port, and a tissue sensor positioned on the cutter and configured to measure a characteristic of the tissue received within the outer port to identify when nontarget tissue enters the outer port. The actuator within the housing is configured to reciprocate the inner cutting member between the retracted position and the extended position to open and close the outer port and cut the tissue.

Abstract: An OCT tracking system includes an imaging unit operable to generate a fundus image of a patient's eye and a tracking system operable to process the fundus image to determine a location of a surgical instrument inserted into the patient's eye. The OCT tracking system further includes an OCT system including an OCT light source operable to generate an OCT imaging beam and a beam scanner. Based at least in part on the determined location of the surgical instrument, the beam scanner directs the OCT imaging beam to a particular region within the patient's eye, the particular region within the patient's eye including the determined location of the surgical instrument inserted into the patient's eye.

Abstract: A surgical probe (e.g., for treating an eye of a patient) includes a body, a cutting element extending distally from the body including a sleeve member comprising a port at an end, and an inner member disposed within the sleeve member, the inner member being movable (e.g., axially) with respect to the sleeve member to open and close the port. The probe further includes an illumination element disposed within the sleeve member, the illumination element configured to project light out of the port.
