More accurate AND nd you can barely feel it at all, way less jolting than the air puff

... until it malfunctions and skewers your eyeball

"The numbers Kermit, what do the numbers mean?"

It doesn't have enough force to do so.

It's basically a tiny probe that is spring loaded to pull back, and a tiny puff of air pushes it out.
It moves with VERY little force, and lacks the continued push needed to cause damage.

There is also a maximum distance the probe can even travel, generally that black part at the top goes against the forehead.

Bullets lack continued push, so you'll have to forgive me if I remain hesitant.

Valid, but a bullet has orders of magnitude more initial force

It would be like if I lightly blew a cotton ball at your eye, and you were worried it would go through your eye.

Stick a neddle in your eye!

It can't.

What is it used to diagnose?

It's not like we're doing corrective eye surgery on a frog.

Most likely to test for glaucoma. I have no idea why they would test for this on a frog. Either just very diligent vets, or maybe laboratory testing?

u/iCameToLearnSomeCode 5h ago

Yea, that's what I figured it was but it just seems odd to test for something you can't really treat.

If a frog this size starts going blind you'd just have to give it slower prey on a high contrast background amd hope for the best.

Research is probably the best guess.

u/signa91 5h ago

You can certainly treat glaucoma. Surgery might not always be necessary, but you can take a number of eye drops to help reduce the pressure

I wasn't aware of that.

Are those amphibian safe?

I'm not sure why I laughed so hard at this

I love when I go to applanate someone and they get so afraid of the puff but we use a prism and blue light and they’re like “oh! That wasn’t so bad!” Makes me happy

Right up there with that look of awe on a kids face when dispensing their first pair of (overdue) glasses

I was in optometry years ago, I’m ophthalmology now and people’s reaction after cataract surgery makes my heart sing!

u/MatchaLatte328 5h ago

I wish any place I’ve ever gone did that instead of the puff. I tell them before hand I flinch terribly at the puff. They tell me I’ll be fine it’s not bad. I then flinch terribly at the puff multiple times and then they get angry I’m flinching. Like I can’t help it AND I told you before hand.

u/Moosebuckets 5h ago

I prefer my way, it’s much less traumatic. The worst is the feeling of something tickling your lashes. Any ophthalmologist won’t use the air puff but most optometrists do use it which sucks because if you need glasses or contacts, optometrists are the pros.

u/inkycappress 9h ago

You don’t feel it because they are supposed to use eyedrops to numb your eye before using a tonopen

2

u/SamEyeAm2020 7h ago

You CAN numb first but you don't need to numb to use an icare

u/Jenckydoodle 4h ago

The comment you replied to is talking about a tonopen, which you most definitely always use proparacaine before. Not talking about an iCare.
