I'm not 100% it's a spit/blink/tear spot, but I am 100% it's on the front
element. There's actually two spots, and the alignment of the two doesn't
match up with the typical alignment you see with the fixation aids, likely
moot anyways as it's a 50x and they didn't feature those.
If I had a nickel for every time someone swore a front element was clean,
only to find it looked like someone had covered it in oatmeal.. Well, I'd
have a few nickels.

Subject: [optimal] artifact issue
Optimalers:
I have a practice with an artifact problem. They are using a Topcon 50X
camera.
At first blush it looks like a typical tears on the objective lens issue,
but fervent cleaning of the lens didn't fix the problem, and it can't be
viewed either from the front or through the minus diopter lens setting. I
have asked 5 times if they are sure they cleaned the lens well.
I am assuming it's something on the objective lens, as it's a white
artifact (I am troubleshooting this over the phone, as they are very rural,
and no chance I will be in their neck of the woods anytime soon. If I am,
something has gone terribly wrong in my career).
I am thinking it's on the anterior surface of the objective lens, but it's
not easy talking someone through dismantling the objective lens over the
phone. Changing filters, magnification and focus doesn't change the
appearance of this artifact. This came on rather sudden as well- not a slow
growing problem.
I have attached the example they sent me- if anyone has any ideas,
thoughts, etc, I welcome your input.
Thanks in advance
