One of the biggest challenges for laparoscopic surgeons is hand–eye coordination within a 3D scene observed on a 2D display. Experienced surgeons learn to use monocular depth cues such as light and shade, relative size of objects, object interposition, texture gradient, aerial perspective, and motion parallax instead of stereovision. Using these cues, all laparoscopic operations can be accomplished; however, time and accuracy may be lost as these techniques do not completely compensate for loss of stereoscopic depth perception [23–32].

The 3D HD view with enhanced haptic feedback makes laparoscopic surgery safer and more intuitive. It improves hand–eye coordination and surgical precision, with the use of all conventional instruments. The 3D view provides increased depth perception and more accurate measurement of the dimensions of the anatomical spaces, enhancing the skills of the laparoscopic surgeon to manipulate tissues, dissect, design surgical strategies, and place intracorporeal sutures. Studies have reported less strain on the surgeon when using 3D rather than 2D vision [33–38].
