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/
