This is a place to share greentexts and witness the confounding life of Anon. If you're new to the Greentext community, think of it as a sort of zoo with Anon as the main attraction.

There's a lot of folks in the comments who are pretty cavalier about the safety, yet the CEO who produces Lasik machines refuses to get the procedure and just wears glasses.
Obviously there's a lot of folks happy with it.
However, many people end up needing glasses within ten years. "Relating to the legal requirements in Germany, sufficient visual acuity was found in 76.7 % of the LASIK group, in 73.9 % of the Ortho-K users and in 85.7 % of the reference group (72.7 % in the adult group, 100 % in the juvenile group)." https://pubmed.ncbi.nlm.nih.gov/23508754/
"Nearly 5% of subjects were dissatisfied with their vision after Lasik... eyes feeling irritated (50%), glare (43%), halos (41%), and [trouble] seeing in dim light (35.2%)." Source: Mamalis N. Laser vision correction among physicians: "the proof of the pudding is in the eating". J Cataract Refract Surg. 2014 Mar;40(3):343-4.
"Lasik Suicide" is a real thing, most of the folks who have been affected don't take the time to say much about the excruciating pain, they just commit suicide.

Definitely think very carefully, your eyes are something you can't fix if you get this surgery. For some people enough nerves are damaged to cause persistent pain that doesn't go away.
I almost got the surgery a few years ago, if it worked 100% of the time I would have taken the risk. But vision is so important that I didn't want to take the risk. Several of my family members did get it and still have dry eyes and halos ten years later, and two now need glasses again anyway.
The sample size of that study was only ~300 people. A study with 20,000 participants in Singapore found that 90% of patients had 20/40 or higher vision after 10 years. It found that high-myopia (-14+)(the most extreme form of near sightedness) patients had a much higher rate of regression, with 39% of those patients losing 2 points or more from their vision within 10 years of tratment (and likely choosing to wear glasses [not listed in the study] or get retreatment [27%]).
So basically, if you have extreme vision problems before LASIK you're much more likely to have to wear glasses again down the road.
Also, worth pointing out that almost everyone will need reading glasses as they age regardless of LASIK. This conversation only surrounds glasses for near sightedness.
Good points. So roughly 10% chance of needing to get glasses or surgery again, which gets higher the worse your vision is to start.
Yep you got it. So for people with only minimal vision issues it might not be worth it, but for those with severe vision problems it may be worth the risk even though their vision likely will degrade slowly back to their original prescription.
Yup friend of the family got it years ago and now sees coronas of light intensely enough while driving at night that they had to stop driving at night in their mid-40s.
