Intraoperative aber-
rometry's time
Intraoperative aberrometry is
one of the latest advances
designed to help surgeons
achieve better astigmatism out-
comes. Typically, a cataract sur-
geon determines the astigma-
tism treatment plan pre-opera-
tively based on the patient's bio-
metry measurements, and does-
n't find out if the astigmatism is
reduced sufficiently until the
patient recovers. Enter aberrom-
etry, which uses a device
attached to your microscope to
analyze a patient's refractive
power in real-time as you oper-
ate.
Aberrometry works by bounc-
ing a light off of the patient's
retina and analyzing the wave-
front that comes back, telling
the surgeon if the astigmatism
has been reduced. The technolo-
gy lets a surgeon know if he's hit
the mark, or if he needs to
rotate the toric IOL or change
the LRI to achieve better refrac-
tive power. It also can guide a
surgeon in choosing the correct
