Key findings
More than 80% of the survey's respondents said they use
toric IOLs in their current cataract surgery practice. Of
the less than 20% who said they do not, 49% said cost to
the patient is a deterrent. If cost was not an issue, nearly
50% said patients with clinically significant astigmatism
would likely receive toric IOLs.
More than 60% of those using toric IOLs think 5 degrees
or less of postoperative rotational error is acceptable, but
29% said 10 or more degrees is acceptable before visual
quality and degradation is significantly affected.
As for toric power calculations, 72% of respondents take
posterior corneal astigmatism into consideration (U.S.
respondents 75% and non-U.S. respondents 69%).
I think the good news is that the number
of surgeons using toric IOLs is starting to
trend upward. It's no surprise that there
is going to be a small subset of surgeons
who do a higher volume of refractive
cataract surgery, as evidenced by the
11% of surgeons who place toric IOLs in
about 20% of their patients. As we know,
there is a third of patients who we are
seeing for cataract surgery with at least
1 D of corneal astigmatism, so there is
a gap in terms of who is getting their
astigmatism fixed and who is not
undergoing this correction during
cataract surgery.
