[Optoelectronic display system for minimal invasive laparoscopic operations: initial experiences with new...

A major aspect of efforts to improve minimally invasive surgery is the optimization of visualization, which is currently unsatisfactory due to the limited number of pixels in the monitors used, and inadequate alignment of the optical axis. Optical systems provided with commercially available head-mounted displays have failed to improve optical quality and significantly facilitate or improve laparoscopic surgery [2,3]. Innovations in the field of consumer video using a new optical prism and a high-resolution matrix (180,000 pixels) are the core elements of a new face-mounted display (FMD-Eye-Trek 700, Olympus Optical Co, Europe GmbH, Hamburg, Germany) that provides high image quality. This device has now been tested for the first time during laparoscopic procedures (n = 14) and combined laparoscopic-endoscopic procedures (n = 7) under clinical conditions. Impressive optical, ergonomic and surgeon-related benefits were established.
