what are the reasons to regret it?

Taran (ex LTT member) has an excellent video on it as he unfortunately experiences negative side effects: https://www.youtube.com/watch?v=xQDAXSbwhR0

Edit: I misremembered, he got PRK, but he does talk about consequences of both methods.

Taran had very strong myopia, with his eyes at -10.00 and -8.50 before the operation. It's not surprising he's dealing with vision issues like starbursts now. The higher the degree of myopia, the more material in the eye they need to remove, which means a higher chance of side effects.

My friends I know who got LASIK had low/medium myopia and didn't end up with long-lasting side effects like Taran. And the starbursts are much smaller and less noticeable in size.

It can damage your eye If the surgeon takes out too much or too little tissue, and make vision worse (astigmatism.)

> LASIK has an excellent safety profile with a low complication rate. In fact, LASIK is one of the safest elective surgical procedures available today, with a complication rate estimated to be less than 1%.

Some people have long term negative effects from LASIK like extremely dry eyes, halos, loss of night vision, etc. These effects vary in severity. A very, very, very small percentage of people who got LASIK had such severe side effects that they committed suicide.

Also LASIK isn’t always going to correct vision to 20/20. Some people end up close.

I had it, or a newer version of it. I had pain before , which I considered to be a migraine, triggered by bad vision in one eye. But the vision was very close to perfect, one clinic refused to do it. After the procedure, and some amount of healing time the vision was perfect, but the pain came back and became stronger. So I suffered strong migraine like pain for years. Untill last month somebody here recommended NAC (N-acetyl-cysteine) supplement, I tried it and it worked within days. Turns out it was just dry eye. I did not make the connection, because eye drops did not help me, they seemed to make it worse. i was not missing in tears, but the eye lubricant which retains the tears on the surface, and multiple doctors missed it.

I never heard about the supplementation of N-acetyl-cysteine with regards to the treatment of dry eye disease (DED). Could you elaborate on your experiences with the supplementation of NAD? I am unable to find any real useful information in the web

This one was probably best https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8234027/

Also read the wiki https://en.wikipedia.org/wiki/Dry_eye_syndrome

Thank you!

There was a FDA document draft released in 2022, page 14 has examples, page 17 has illustrated examples https://www.fda.gov/media/160239/download

There is no way to prove it, but I am pretty sure I developed Keratoconus due to Lasik.

Are you attempting to fix it?

I am tempted to get a contact lense inserted into one eye to correct it.

I think I developed it as due to Lasik, but it only occurred in my left eye. My right eye is still good.

I only got CXL. After that experience, I am not too tempted to mess with my eyes anymore :(

Because most likely that was only the trigger

Keratoconus has a strong genetic component. And should have been screened (using the corneal scan) prior to surgery

But of course a surface that is frail is going to become more frail after surgery

There was screening. They said the cornea was a bit weak, but still fine… Last time I checked it wasn’t yet declared a genetic thing and there is no history of Keratoconus in my family.
