A Study of Teleoperation Methods in a Simulated Virtual Eye Surgery Environment (2507.13654v1)

Abstract: This paper examines the performance of Inside and Outside Control modes at various scaling factors in a simulated vitreoretinal surgical setting. The IRISS teleoperated surgical system's console (cockpit) was adapted to project a simulated microscope view of an intraocular setup to a virtual reality (VR) headset. Five experienced vitreoretinal surgeons and five engineers with no surgical experience used the system to perform tasks common to vitreoretinal surgery. Experimental results indicate that Inside Control methods at higher scaling factors (20 or 30) achieved the best performance overall, though the optimal scaling factor may vary by task and complexity. Optimizing control methods and scaling factors could lead to improvements in surgical efficiency and accuracy, as well as minimize risks in future robotic-assisted intraocular procedures.
