Presbyopia-correcting IOLs
Average annual procedure volumes show that ASCRS
members are performing almost three-quarters of the
cataract surgery performed each year in the U.S. Nearly
25% of respondents performed more than 600 procedures annually. While the average incision size was 2.5
mm, 31% use an incision of 2.2 mm or smaller. While the
average number of vitrectomies following cataract surgery
was 6.5, 52% of respondents had two or less a year.
More than 50% of surgeons are implanting 5% or less of
their cataract patients with a presbyopia-correcting IOL.
International surgeons had a slightly higher average
percentage of conversion to these lenses. Interestingly,
the percentage of cataract patients getting a monovision
procedure is almost twice that of those getting a
presbyopia-correcting IOL.
While most doctors believe that vision at all distances is
equally important to patient satisfaction with presbyopiacorrecting IOLs, almost one-quarter thought that either
distance vision or near vision was the predominant driving
factor.
When asked how much residual sphere and cylinder was
considered acceptable before it started to affect visual
quality, respondents answered 0.61 D of sphere and 0.71
D of cylinder on average. 18% believe that cylinder levels
OVER 0.75 D still did not have a significant impact, while
13% believe the same for sphere. When asked how they
resolve this residual error, 39% do something other than
laser vision correction.
