Astigmatism
Management
Key Findings:
Educational initiatives are
necessary to provide insight
and close educational gaps
pertaining
to reducing the level of
rotational error from the intended
axis, accurately assessing power
and axis levels, and the alignment
of pre- and intraoperative intended
axis.
ASCRS members reported that the
average acceptable rotational error
from the intended axis in toric IOL
patients is 6.6 degrees.
29% of toric IOL surgeons
believe that 10 degrees or more
of postoperative rotational error
is acceptable with a toric IOL
before visual quality and acuity are
significantly affected.
36% of respondents are using
anatomical landmarks or ink marking
without the aid of axial instruments.
Almost 50% of respondents
report using the average 0.5 D
to determine their surgically
induced astigmatism.
"
Obtaining the best result from the
use of a toric IOL requires fastidious
attention to detail. Many practices
and technologies may have been
adequate in the past; however,
patient expectations of excellent
uncorrected vision require a more
controlled approach. We look forward
to educating on the full continuum of
technologies and approaches for
astigmatism management to help
improve patient outcomes.
