Abstract
Purpose :
The Beyeonics system is a digitally enhanced surgical visualization system that was adapted from a fighter pilot technology. It consists of a head wearable display, and a high-resolution 3D imaging and software platform. The head display projects magnified images and data from multiple sources and is controlled by intuitive head gestures. Due to the use of head wearable display and head gesture usage, concerns were raised about the learning curve, fatigue and discomfort, which may rise during intraocular surgery. Thus, a clinical study was initialized aimed to compare surgeons' opinions and comfort levels using Beyeonics system, as well as performing a primary evaluation of anatomical surgical results.
Methods :
Five surgeons performed the total of 34 surgeries using the Beyeonics system. 9 surgeries were cataract extraction performed by anterior segment surgeon (DV). All other surgeries were primarily vitrectomies with/without cataract extraction-performed by experienced vitreoretinal surgeons. Ergonomics, educational value, image sharpness, depth perception, field of view and technical skills were analyzed through analysis of a questionnaire, comparing surgeons experiences to normal microscope usage.
Results :
34 patients were enrolled in the study. Surgeries included cataract surgeries (9) and variety of vitreoretinal procedures, including vitrectomy for retinal detachment, ERM removal, vitreous hemorrhage and silicone oil removal. Depth perception was rated similar to normal microscopy. Field of view, educational values and image resolution were rated superior when using the 3-D system. Color perception and ergonomics were rated superior when using traditional microscopy. All 34 surgeries (100%) achieved anatomic success with one surgery.
Conclusions :
The Beyeonics system was superior from an ergonomics perspective, as compared with the microscope. It enabled the physician freedom of movement, operating while being aware of the happening in the OR. Physicians reported a short learning curve and was described by surgeons as equal or superior in most surgeries performed. The head-wearable display system is offering a novel way of operating which may become a new standard for ophthalmic surgery as ongoing improvements are applied.
