ABSTRACT
At present, vitreoretinal surgery has gradually entered the era of minimally invasive surgery, and high-speed vitrectomy, micro-incision approach and wide-angle illumination have also pushed it to a higher level. Minimally invasive vitreoretinal surgery has become one of the key and difficult points in the teaching of ophthalmic microsurgery. The three-dimensional (3D) surgical display system can provide high-resolution, multi-level magnification, and stereoscopic images for surgery teachers and multiple observers at the same time, breaking the traditional "one-to-one" teaching of the main surgeon and assistant mirrors, realizing "one-to-more" and "head-up" surgery teaching, and thereby improving the teaching effect of vitreoretinal surgery.
