What is 3d laparoscopic surgery?


Laparoscopy enabled the advent of minimally invasive surgery, encompassing many advantages such as smaller surgical wounds, less postoperative pain and shorter hospital stays (1,2). However, it also has its unique limitations (3); one of them being loss of depth perception and surgeons need to acquire the psychomotor skills to work with two-dimensional (2D) images. Three-dimensional (3D) laparoscopy has been introduced to address this issue.


Three dimensional, or 3D, laparoscopic surgery allows surgeons to perform procedures with greater speed and accuracy -- shortening operating times and improving surgical outcomes. 3D laparoscopic surgical video systems can be used to perform minimally invasive surgeries.


Principles of 3D laparoscopy






Depth perception is the ability to estimate and interpret the relative distances of different objects by our eyes. The human brain estimates the depth of the object based on five major principles: stereopsis, parallax, depth of field, environmental context, and tactile feedback. Parallax is the difference in relative positions of objects as the observer move and views the objects from different point of views, in which monocular vision is sufficient. On the other hand, stereopsis relies on the identification of disparities between two eyes in binocular vision to allow the brain to compute the relative depth of an object (4). When viewing a motion picture on a monitor, as in the case of a laparoscopic procedure with the conventional 2D laparoscopy, stereopsis is lost and relative distance is perceived by analyzing visual clues. 3D laparoscopy uses two cameras instead of one to recapitulate the effect of human binocular vision: producing two different views of the same object, which are then co-displayed on the screen with oppositely polarized lights. Eyeglasses containing oppositely arranged polarizing filters on each side allow each eye to view differently in accordance with the two cameras’ arrangement, permitting depth perception by stereopsis. It is worthy of note that not everyone possess the ability to perceive depth by stereopsis, and 3D laparoscopy would not have any additional effects in these individuals.
