Lasik corneal thickness and pupil size

[chantana]

Hi! Sorry, this isn't exactly related to diving anymore, but I had such a large response and helpful response before I hope you don't mind posting about this.

For those of you who did lasik, do you remember what your cornea thickness and pupil sizes were?

My corneas are 529 and 537 which they say is average and my pupils are 6.5 and 7 which is larger than average. I'm cleared for lasik but they said that I can only have it once and there won't be enough cornea for a second go if I need an enhancement. I've got quite a high perscription.

I think I'm going to not do it, I see excellent with contacts and just feel it's too much of a risk to spend all that time and money and end up stuck wearing glasses or special contacts if they screw it up. Maybe in the future the procedure will get better.

Anyway, not sure why I'm posting other than to see if maybe someone thinks I'm making the right decision or not. It would be so cool to not have to wear contacts while I'm diving. But it's so cool to be able to see at all like I can right now...

Had I been in your position I would not have had it done either. I don't remember exactly what my cornea size was but it wasn't an issue (could have handled more than 1 correction if it had been necessay). My pupil size was rather large however, 7mm+ which is the absolute max size my doctor would allow. It did cause me to have rather large halo's when I'm very tired.

Best of luck.

what are your numbers?
i have astigmatism ( -7.0 and -4.5 diopters), thin corneas , and big pupils. all the wrong things for correction.

a full correction was not assured ( not enough cornea to remove) and it would have made me instantaneously need reading glasses, which i do not normally need now, and there is a risk of abberations (halos etc.)

when you are in the "experimental" range with a higher risk of bad or unsatisfactory results , your eyesight is not something to be cavalier about.

i have prescription ground mask lenses and a small reading lens glued to the lower corner of my left lens.
in low light conditions i need the reading lens to read my spg
this setup works great, my vision is excellant i do not have to worry about problems with contacts underwater.
maybe as the technology improves i will reevaluate surgical correction, but for eyes that need lots of correction and are anatomically imperfect like mine, the downside is too great.

let us know what you do

I am -9.00 diopters in both eyes no astig.

My eyes see 20/20 now with contacts and I can wear focus dailies with no problems all day but do have to take them out at nite.

I did a lot of research and even if you are a perfect candidate, there is a lot to think about. if you are less than a perfect candidate, i think it's best to wait for technology to catch up. why damage something that is already good?

i'm not going to not have the surgery, it's just postponed 5 or 10 years. i don't want to end up blind or seeing worse than i do now, or even just have wasted the money and end up back in glasses again (your cornea is changed and you can only wear special contacts after surgery).

thanks for posting and good luck to you.
