Cool tests. You said tests run with loupes had the same results, right? How did you run the loupe test?
You’re holding the loupes right in front of the PerioLase meter and directing the laser right into the loupe lens?
When we are operating, the laser beam is always directed away from the eye, to me this makes it even safer. Good thing. Where are those darn loupe filters I had anyway, some where around here.

What about a carbon dioxide laser wonder if it would be any different?

It’s just age Ron. When I had the photorefractive keratotomy in 1997 my doctor said “You’re still gonna have to get the little grandpa readers when you turn 42”. I still have perfect vision at distance.

Ron,

Great test!

Ummmmm………….

I started forgetting to put the right laser glasses on about 14 years ago.

I’d put the Nd:YAG glasses on, then take them off to put on the Argon surgical glasses, then the Holmium, then ………

When I got confused and used the Argon glasses with the Nd:YAG laser, and I didn’t go blind I stopped using glasses.  Really haven’t for over a decade and that inclde using a microscope all that time.

No changes in  my vision.  I’m 48 and no presbyopia.  I still need glasses for distance as I have fo 25 years.  

Having said that, we train our doctors to wear safety glasses.  “Do as we say, NOT as we do.”  Also, when the new filter for the Global scope comes out, I’m gonna buy it as it sets the right example and won’t interfere with the vision.

But I think it was always a question whether the scope was increasing the focusing of the diverging Nd:YAG or other beams when I was using it.  We have hand-held power meters that we can test with, but I doubt it would show much difference–other than they are more sensitive to powers below 1 watt.

Del  feels the scattered near-nfrared light he gets from biostimulating his sinuses has been the reason he no longer wears corrective lens?

Allen, I’m thinking about getting refractive surgery.  Any focusing problems up close to near as in he practice of dentistry?

Nice post Ron.

Bob
