Had LASIK and there are some holes in your logic
first off , complications, they are generally minor and can be resolved. Too much cheese gives me complications. My cousin had complications and the other was flat out rejected. Side effects can last a while, months even, no worse than side effects of contact lenses.
secondly, trust issues on cornea thickness. There has been millions who have it done, I know a ton, haven’t seen a single person lost vision. This procedure is rather mature, like boob jobs.
third, this is an elective surgery, their marketing is profitable, not grossly. I got serious discounts on my eyes (haggling), you don’t have to get it, unlike many other racketeering practices like healthcare in general.
Lastly, you have two eyes and it’s done one at a time, there is room for error. I know women that have died giving birth, it’s about perspective.
the eye can be a scary place to get surgery, but having been through way worse medical trauma to the eye for my daughter and tens of thousands in costs, if eye surgeons can handle that, lasik should be cake.
