the procedure," he says. "Some patients want vitrectomy results with
the relatively low risk of YAG laser vitreolysis, and that's not possible.
If you want a completely clear vitreous, you have to do a vitrectomy."
Inder Paul Singh, MD, an ophthalmologist at the Eye Centers of
Racine and Kenosha, Wis., is effusive with his praise for Dr. Shah's
research. "It's a landmark study for modern vitreolysis, because it's
the only one that's been done using the new laser technology," he
says. "The laser has changed, so the safety and efficacy of the proce-
dure has improved."
Dr. Singh says the latest version of the SLT-YAG combination plat-
form used to pulverize floaters features an LED light source, which
lasts longer and produces less glare in the visual field than the older
model's halogen light source. More importantly, says Dr. Singh, the
aiming beam has
changed from red to
green. "Red light has a
longer wavelength,
meaning it gets
absorbed in the red
reflex of the light
source," he says. "The
green aiming beam is
easier to see in the
middle of the vitreous
when you're training
it on floaters."
Dr. Singh says
potential future
upgrades to the laser
platform include pat-
