Depth Perception of Surgeons in Minimally Invasive Surgery

Area of Science:

• Surgical Visualization
• Medical Imaging
• Human Factors in Medicine

Background:

• Minimally invasive surgery (MIS) limits surgeons' natural 3D depth perception.
• Reliance on monoscopic cues in MIS can lead to spatial misjudgment and potential patient safety risks.
• Understanding surgeon visual challenges is crucial for improving MIS outcomes.

Purpose of the Study:

• To review natural human depth perception and cues available in open surgery.
• To identify depth cues lost in MIS and surgeon compensation strategies.
• To explore and evaluate innovative solutions for enhancing 3D visualization in MIS.

Main Methods:

• Review of literature on human depth perception and visual cues.
• Analysis of visual challenges specific to the MIS environment.
• Survey of recent technological advancements for 3D image presentation in surgery.

Main Results:

• Open surgery utilizes multiple depth cues, while MIS relies on limited monoscopic information.
• Surgeons develop compensatory strategies for the lack of binocular disparity in MIS.
• Various technologies, including 3D monitors and head-mounted devices, aim to restore depth perception.

Conclusions:

• Addressing depth perception deficits in MIS is critical for surgical performance and patient safety.
• Technological innovations offer promising avenues for improving 3D visualization during minimally invasive procedures.
• Further research into optimal 3D display technologies is warranted to support surgeons effectively.
