Provided herein is a probe for treating an eye of a patient. In one or more embodiments, the probe includes a body, and a tubular element having a main lumen extending from the body, the tubular element comprising a distal end. The probe further includes a visualization optical fiber within the main lumen, the visualization optical fiber adapted to emit an illumination provided by at least one of a plurality of light sources connected to the visualization optical fiber. In some embodiments, the probe further includes an optical switching system (e.g., a time-division multiplexor) operable with the plurality of light sources, wherein the optical switching system is adapted to independently control each of the plurality of light sources. By providing time-division multiplexing between different surgical light sources, quasi-simultaneous illumination delivery through the same optical path may be achieved.
