useful to cataract surgeons. On the contrary, I
have found that intraoperative OCT has opened
up a new dimension in phaco cataract surgery."
First and foremost, Dr. Yeoh said intraopera-
tive OCT is helpful for the teaching of trainees.
"We are operating on a 3-D structure, and
intraoperative OCT allows us to see the eye
in cross section during surgery," he said. "This
leads to a better understanding and apprecia-
tion of the surgical anatomy and fluidic move-
ments during cataract surgery. This in turn is an
invaluable aid to trainee cataract surgeons who
get far more information compared to just a
microscopic view."
Dr. Yeoh noted how with intraoperative
OCT, a trainee can see and adjust his or her
technique while sculpting a groove in the nu-
cleus (Figure 1). When inexperienced, knowing
how deep to create a groove or how it should be
shaped can be difficult.
Dr. Yeoh said intraoperative OCT is also
helpful in diagnosing a posterior subcapsular
cataract vs. a posterior polar cataract (Figure 2)
and showing pseudoexfoliation material on the
anterior lens surface (Figure 3). He admitted
that while this function "gives us pretty pic-
tures, [it] does not always contribute to better
or safer surgery."
Intraoperative OCT has helped surgeons see
and better understand where the fluid planes
are in hydrodissection and hydrodelineation.
