Abstract
Purpose:
This work assesses the educational use of a 3-dimensional (3D) heads-up visualization system for vitreoretinal surgery.
Methods:
A cross-sectional survey was performed among 18 medical students, 18 residents, 7 VR fellows, 6 nurses, 4 anesthesiologists, and 3 surgeons on their experience with the Ngenuity 3D Visualization System (TrueVision and Alcon) compared with the standard microscope.
Results:
Most medical students (88%) reported better identification of surgical landmarks; 63% ranked the Ngenuity as their preferred method of learning (vs microscope or 2-dimensional display). Residents reported a superior understanding of anatomy (69%), an increased ability to ask questions (63%), and improved ergonomics (94%). Epiretinal membrane peel, internal limiting membrane peel, and core vitrectomy were most enhanced (69% to 77%) for residents. Fellows’ experience with trocar placement, vitrectomy, and oil/gas insertion was the same as before (67% to 100%), whereas endolaser and closing were worse (67% to 100%). Regarding autonomy, 83% of fellows reported no change, whereas 17% reported increased levels. Nurses were better able to track case progress (67%) and anticipate which tools were needed (50%). All anesthesiologists reported the same or worse engagement in cases, noting it was difficult to switch between the 3D screen and the anesthesia equipment. All surgeons reported a better awareness of trainees in the room and an improved ability to point out landmarks; 67% reported being more comfortable with resident and fellow autonomy.
Conclusions:
The Ngenuity is most helpful to students and residents. Integrating 3D displays into the surgical curriculum is beneficial, with care to ensure nurse and anesthesiologist satisfaction.
