Myopia Yag laser

[ardyp]

Hello everybody,



my father is an optician and do have a Yag laser like the one in attachment for myopia. This should be a Yag/Argon laser, do you know how much is rated in mw? I can say to you that he do have 2 big tanks with nitrogen i think for cooling or something.


Bye

Lots n lots n lots, most probably... The Medical Lasers board has been deleted, sux2bU!

Oh wow!

Ask your dad if he'll let you use it to pop balloons ;D

 

[VillageIdiot]

Yeah, I mean if you damage your eyes in the process... you're prepared!! ;D ;D ;D

lol sometime i go with him inside the operation room(i'm a medicine student) and it's great how the laser burns the eyes of people, you can even see the little "smoke" coming up... ;D

One time we tried to make a hole in a box and it takes only 2 or 3 shots(actually you shot with a pedal) but the hole was really little :-?



I will ask my father's assistant, cause i know that my father will not answer my question! :-/

Oh... man...

So...cool...

Wish my dad was that cool Coolest thing my dads done is that he's been to Antarctica a dozen or so times. No lasers there :-/

Of course the hole is small, the beam must be focused to a pinpoint.But lol, avoid eye exposure doesn't work here ;D It should be able to pop a balloon in a single pulse.

well trust me, he is not cool at all, he only need need it for work... :


The assistant is pretty cool, cause is only 5-6 years older than me so we have lot of fun together...

i dont think it should have HUGE power as you think. you really dont need 1W to burn somebody's eye

But if it's myopia it's fixing, the retina shouldn't be the target

you are right, the target should be the cornea...

On a scale of 1 to jello, how sure are you this isn't an excimer laser?

 

[ardyp]

i'm not really sure what kind of laser is this, but actually the dot is visible when you shot and it's red.

I 'm not 100% sure about what i say... :-/

You may be viewing incandescence rather than a direct reflection. The "dot" of my CO[sub]2[/sub] is white, but 10.6µm radiation is not. Surely it has a safety label you can read?

If the laser is for the treatment of myopia then it would have to be an excimer.....if there's a red dot then that probably is some sort of targeting beam.

Argon lasers for eyes are used to cauterize leaking blood vessels in the retina, but they are usually smaller than this laser and all the photos of these lasers I've ever seen it looks as though the patient is treated while he/she sits up, rather than laying flat.

I did ask an eye doctor a long, long time ago (not long after I had my near-sightedness permanently banished by an excimer laser) how many watts in the beam, and he said something like "a few millijoules". Being that UV is higher energy + pulsed I don't think it would take much to ablate away corneal cells. But when I had my surgery, I do recall seeing both a red and green light shining in my eye.....I doubt they were lasers as I was told to stare into the lights.

But I'll say one thing....I do distinctly remember the burning hair stench of my corneas being partially vaporized! Gee I guess I'm the only one here who has smelled their flesh being vaporized by a laser....not something you want to smell, even if you are having surgery!

I had lasik a few months ago - not a lot of fun
