ARASH:ASiST includes two similar devices specially designed to operate as a training system for minimally eye surgery. These similar devices operate as a dual haptic-surgery robot. In minimally invasive vitreoretinal eye surgery, unlike a general surgery, it requires 3 degrees of freedom to cover a spherical workspace. ARASH:ASiST operates as a mechanically remote center of motion (RCM) mechanism to provide the required spherical workspace for vitrectomy eye surgery and provide a safe environment for the robotic surgery process. In minimally-invasive eye surgery, the surgical instrument enters the patient’s eye through a small incision, and the surgery process takes place around this pivot point. Video © Ali Hassani
