He mentioned both non-normal dis-
tributions and single lens constants.
He mentioned refraction predic-
tion error, which is the main measure
of performance. Mean numerical
error tells how formulas consistent-
ly perform. You also look at RMS
How are we doing? Across the
board, cataract surgeons are about
74% within about 0.5 D of target, he
said, but can improve to 92%.
Sources of error in IOL power
calculations include effective lens
position, postop refraction, axial
length, and corneal power. People
are trying to get around this, he said.
As formulas have evolved, they've
incorporated various ways to get
around or mitigate some of these
sources of error, but modern formu-
las are black boxes. You can study
how they perform, but we don't have
insight into their inner workings.
Things break down when
patients' eyes are more atypical,
Dr. Weikert said. He took a quick
detour to discuss statistics. There's
confusion and debate on how to best
analyze performance in atypical eyes.

Main Stage session featured a
guest speaker, a special panel
featuring female leaders in
ophthalmology, and the Binkhorst
Lecture.
Binkhorst Lecture: IOL
calculations in atypical
eyes
This year's Cornelius D. Binkhorst,
MD, Lecture was given by Mitchell
Weikert, MD, who spoke on the topic
of IOL calculations in atypical eyes.
He said that this is an important
topic and an area where his team at
Baylor has done a lot of work. Dr.
Weikert said he was also hoping that
attendees would walk away with
several pearls from his lecture to use
in their practices.
