A microsurgery simulator simulates various microsurgical procedures (e.g., nerve reapproximation, ear drain deployment) that utilize a surgical microscope. A surrogate surgical microscope includes a mobile device and an eye piece. A physical surrogate surgical interface represents an interface between a user and a simulated surgical scenario. Sensors sense the user's manipulation of the surrogate surgical interface. A surgical simulation generator generates a real time 3D surgical simulation based on the sensed manipulation. The generator renders the real time surgical simulation into a real time computer graphics generated video representation that is displayed on a screen of the mobile device. A processor of the mobile device is configured to perform at least a portion of a computational analysis that is used to generate the real time computer graphics generated video representation.
