Dr. Ristvedt and Dr. Swan said they wait up
to 3 months to get repeat measurements that
are consistent before scheduling the patient for
a LASIK fine tune.
How much residual astigmatism is impact-
ful enough to correct? Dr. Wiley's comment
about patient perception comes into play here,
but Dr. Berdahl said he and his team recent-
ly analyzed their data as they corrected low
amounts of residual astigmatism (0.5–0.75 D)
with LASIK and found it had a meaningful im-
pact on patients' visual acuity.
Dr. Swan emphasized the importance of
following the entire optical path through the
eye before taking corrective action, making
sure that things like dryness, lens positioning,
early PCO, or low-grade CME aren't the cause of
refractive error.

"Rule out all treatable causes and also rule
out the potential untreatable causes that might
be the real reason and don't try to blame the
astigmatism," Dr. Wiley said.
