Can seeing a surgical site in 3D
improve procedures and outcomes?
Would you rather have surgeons oper-
ate with one eye open or both? That's
really what it boils down to once all
potential obstacles related to 3D are
overcome. All else being equal,
enabling depth perception can only
help.
Dr. Renton has seen both the advan-
tages and challenges of working with
3D-equipped endoscopes. He isn't ready
to fully embrace the technology yet,
noting issues with eye fatigue,
headaches, and getting stereoscopic
projections to line up perfectly.
"Eventually I think it may become
something we use all the time in every
case, but I don't think the technology is
there yet," he says.
The development of deflectable-tip
3D laparoscopes is a big step forward.
Previously, says Dr. Renton, tilting the
camera to try to look around corners
offset the horizon, causing the image to
blur. "And someone in the OR invari-
