Our training lab uses an Leica M651 microscope which is very nice but also very expensive
Chung and his colleagues from South Korea describe using the Nikon SMZ645 microscope for training. Their used microscope had a working distance of 115 mm which is too close for proper microsurgery. They modified it with a 0.7 auxillary objective lens which increased the working distance to 150 mm.
