The change is relative
Relative to:
Individual corneal "softness"
What kind of dilation, how much dilation
What is the question, what is the answer?
I don't believe any hard fast rules
BUT, if basing premium IOL Toric Multifocal Post LASIK calculations on
Topography I want the MOST VIRGIN cornea can get
In this case, every micron counts.....

We never did a Pentacam post dilation when I was working, it effects the
reading due to the way the drops interact with the cornea.
Our Cataract and Refraction specialist, Dr. Michael Goggin showed me first hand
how much it changed the readings, and that convinced me.

I was going to send this question directly to Denice Barsness but thought the
information may be beneficial for all who perform corneal topography...
Do you perform corneal topography always pre-dilation? We have been doing
this but performing post dilation is better for our patient flow...
In which instances must this always be done pre-dilation and when is it
acceptable to perform after dilation. Or does it not matter at all?
Looking forward to your response.
