Hi Joe:
Sorry to hear that you are going through this. If you want to feel scared or angry, go right ahead.
We’re all Human after all. I didn’t feel scared the first time I went for the laser since the Dr. said
it wouldn’t hurt .
Okay with most People, that may be true. I have talked to many and they said
it didn’t hurt. I guess my eyes are just more sensitive than others. I carry this “chicken” label on me.
“Do what you want to me but DON’T touch my eyes unless you put me out first.” 
For several reasons, I needed laser for Retinopathy 22 yrs. after being dxd. I was
25 at the time. I don’t recall my Ophthalmologist mentioning the optic nerve so you should ask
yours to explain about that, so you will understand it. I find most Specialists explain as little as
possible unless you happen to know what questions to ask them at the time.
Anyways, I only had to get my left eye lasered since my right has always been fine. I had 250 shots
the first visit. I found it Very uncomfortable, right up to painful burning even. So much so, that I made
the occasional movement while he was lasering my eye which didn’t please my Ophtho much. When
I was leaving, he asked if I wanted him to freeze my eye at my next appointment, not explaining about
the freezing, of course. I’m thinking, “eye drops”. NOT!
The next visit, he told me to close my eye since he was going to freeze it. What??? He’s got this long
hypodermic needle heading for my eye and had it stuck in my eye socket and under my eye before I
had a chance to comment. He was SO fast. (You better believe, I did make a few choice comments
after the fact
).
So then, my eye was frozen, no movements from me during these 250 shots. (I actually dozed off since
he had my head held in a lodging and a circular thingy in my eye to keep it open. I had to wear a patch for
a couple days and I had a black eye for about a week(from the hypo). I had “star wars” nightmares for
about a month. That was it. That was 24 yrs. ago. I’ve never needed any more lasers. At my last eye
appointment, my Ophtho said my eyes looked beautiful and he doesn’t need to see me for a year.
I’m sure that you will do much better and I bet it won’t hurt you at all. Don’t forget, the laser eqiupment
that they had 24 yrs. ago was quite primitive compared to the ones they have nowadays. Good Luck!
I didn’t have much time but I just found this for you if it helps:
Healthy optic nerve illustration.
More eye anatomy information.
The optic nerve, which is the nerve that takes all of the visual information from the retina to the brain, can sometimes become swollen in diabetics. The cause of this optic neuropathy is unclear but it may also be due to insufficient blood supply. Like the nerve palsies mentioned above, the majority of these optic neuropathies resolve on there own over several weeks. Overall, this is an uncommon problem in diabetics.
