    Abstract: An ophthalmic surgical instrument for delaminating a retinal membrane includes a handpiece and an actuator mounted on the handpiece. An outer tube has a proximal end mounted to the handpiece. A dissection spatula is extendable outwardly relative to a distal end of the outer tube responsive to movement of the actuator, the dissection spatula defining a channel connected to an opening proximate a distal edge of the dissection spatula. A dispensing system is in fluid communication with the channel. The dispensing system may include a reservoir within the handpiece. The fluid may be dyed blue to enhance visibility of a delaminated portion of the retinal membrane.

    Abstract: An ophthalmic surgical instrument for peeling a retinal membrane includes a handle and an actuator mounted on the handle. A first arm and a second arm extend outwardly from a distal end of an outer tube mounted to the handle. The first arm includes a first pulling surface and a first gripping surface and the second arm includes a second pulling surface and a second gripping surface. The pulling surface of each arm is substantially perpendicular to the gripping surface of each arm and the gripping surfaces of the arms face one another. The first pulling surface and the second pulling surface move toward one another when the outer tube is extended over the first arm and the second arm in order to raise a flap of the retinal membrane that is then gripped between the first gripping surface and the second gripping surface.

    Abstract: A surgical microscope is configured to capture images of an eye of a patient and defines an optical axis. An illumination source is configured to emit a plurality of beams onto the eye of the patient at a plurality of angles relative to the optical axis. A controller is coupled to the surgical microscope and the illumination source, the controller configured to independently control values for illumination parameters for each beam of the plurality of beams to facilitate imaging of the eye of the patient. The illumination parameters may compensate for reflections from the iris, offset of the eye relative to the optical axis, and reflections of ambient light. The illumination parameters may be controlled subject to inputs received from a surgeon or other user.
