Toric IOLs
Conversion to toric IOLs was higher with international
surgeons versus U.S. surgeons, and more than twice the
conversion rates for presbyopia-correcting IOLs. When
asked what amount of rotational error from the intended
axis was acceptable before it affected visual quality and
acuity, the average was 7.2 degrees, and one-third of
respondents set this threshold at 10 degrees or higher.
When targeting toric IOL calculations, about half of
respondents target the lowest level of error regardless of
axis, while the other half choose the lowest error but keep
the same preoperative axis, never wanting to flip the axis
on these patients.
When calculating the power of toric IOLs,
respondents use the IOLMaster the majority of the
time with topography as the second most common
option. Manual Ks were an interesting third choice.
When deciding on the axis of toric IOLs, topography
becomes the primary diagnostic measure, with
IOLMaster as a second option, and manual Ks
continue to be a third option.
