That's weird, almost looks like newton rings. I assume you've tried artificial
tears to give the smoothest optical surface you can get?

All of our patients are well dilated. Today's two patients were both phakic.

Can you give us a little more information? Is it happening with all patients
across the board? Dilated, undilated? Both phakic and pseudo-?

We are slowly learning to use the Clarus 500. The color images are superb and
typically without artifacts.
The green FAF images, however, are not up to par as almost every picture
displays a series of dark concentric rings in the periphery along with uneven
illumination, nasally and temporally.
Because of our relative inexperience with this instrument, we don't know if the
cause is operator, patient, or equipment related. What do you think? How can we
eliminate these unwanted artifacts.
