The largest challenge for laparoscopic surgeons is the eye-hand coordination
within a three-dimensional (3D) scene observed on a 2D display. The 2D view on
flat screen laparoscopy is cerebrally intensive. The loss of binocular vision on
a 2D display causes visual misperceptions, mainly loss of depth perception and
adds to the surgeon's fatigue. This compromises the safety of laparoscopy. The 3D
high-definition view with great depth perception and tactile feedback makes
laparoscopic surgery more acceptable, safe and cost-effective. It improves
surgical precision and hand-eye coordination, conventional and all straight stick
instruments can be used, capital expenditure is less and recurring cost and
annual maintenance cost are less. In this article, we have discussed the physics
of 3D laparoscopy, principles of depth perception, and the different kinds of 3D
systems available for laparoscopy. We have also discussed our experience of using
3D laparoscopy in over 2000 surgeries in the last 4 years.
