A microsurgical laser probe has a handle and a tubular tip that projects from the handle, and three optic fibers that extend through the handle and the tip. One of the optic fibers is a laser optic fiber that is adapted to be connected to a source of laser light at one end of the laser optic fiber, and to transmit the laser light from the opposite end of the laser optic fiber at the distal end of the instrument tip. The other two optic fibers are illumination light optic fibers. Each illumination light optic fiber has one end that is adapted to be connected to a illumination light source, and an opposite end that projects the illumination light from the distal end of the instrument tip. By providing two laser light optic fibers in the instrument, the amount of illumination directed to the surgical site being accessed by the laser optic fiber is effectively doubled.
