Intraoperative
aberrometry
Dr. Whitsett will not
operate on post-
refractive patients
without referencing
intraoperative wave-
front aberrometry,
which combines real-
time information
about the eye's opti-
cal characteristics
with pre-op biometry
data to let surgeons
better predict the
optimal lens power that results in the best refractive outcome.
"For us to operate without being able to scan eyes in real time
involves our best guess [of the optimal implant placement]," says Dr.
Whitsett. He says his surgeons switch out lenses 25% to 30% of the
time based on intraop aberrometry readings. "Usually by only half a
diopter," he says, "but that's oftentimes the difference between happy
and unhappy patients, and patients who need post-op vision enhance-
ments and those who don't."
Newer wavefront aberrometry platforms are user-friendly and
linked directly to surgical microscopes, notes Dr. Krueger. "If you
have real-time wavefront information and perform surgery in a consis-
tent manner, you can use intraop data to predict surgical outcomes,"
he says.
Dr. Galor finds intraoperative aberrometry helpful in patients who

The next step in multifocal lens development
is to come up with implants that are more
forgiving and that provide depth of focus
without post-op visual side effects.
