Getting LASIK never made sense to me given the risks. Essentially, take a very very low risk of permanent eye problems to not have to wear contact lenses. I'd rather pay for contact lenses forever, put them in, and take them out every day than risk anything to my vision. Obviously contacts have risks as well but infinitesimal if used correctly.

Permanent changes can't be undone for newer advances and options that come out in the next 30-50 years.

Glasses are annoying, and I’m not particularly risk averse, but unless I was completely blind or in excruciating pain, I can’t imagine any scenario in which I would elect to have someone cut, lase, or reshape my eyeball.

Everybody I know who had LASIK is thrilled with the results. Even the ones with complaints consider them minor compared to being able to see from the moment they wake up in the morning.

I'm still not gonna let somebody shoot my eyes with lasers. I'm just terrified that something will go wrong, and it won't be fixable. But that terror isn't justified by either anecdotal experience or the overall statistics.

My eyes are naturally about diopter 12.

I found the risk/reward ratio of surgery* acceptable.

* Lasik is only used up to about diopter 6ish; I had ICL surgery.

That'd be nice. I had LASIK a few years ago and the number of Windows Vista generic error sounds (BONG BONG) I heard during the procedure was a little unsettling. Ended up working out just fine though, so far at least. EDIT: Given some of the comments below, for reference: mine was done almost six years ago.

The fact the procedure involves me looking down the barrel of a flesh-vaporizing laser has always has made me reconsider.

That's an advantage of ICL over Lasik: the surgery is minimally invasive, and completely reversible (assuming no catastrophic accidents during surgery itself).

A 3mm-long slit is made at the very edge of your iris, and the lens is inserted, then unfurled in place. Reversing it involves pulling the little sucker back out, easy-peasy. I've had that done, during cataract surgery.

It's not risk-free, but it's ostensibly MUCH safer than Lasik. We don't have enough data to make that a stronger certainty, though.

Lasers are not fun. Especially when they're not aiming at the cornea/etc flap and instead are intentionally burning your torn retina flap to "photocoagulate"/glue it back on to the back of they eyeball with the rest of the retina. It hurts quite a bit (like getting punched in the eyeball 300 times) and you have to remain perfectly still with your eye always looking at the the same exact spot for 20 minutes minutes wh…

Wow, TIL. My ICL surgery was, IIRC, much faster, too. Of course, all the real work was done upfront, so there was no during-surgery shaping to go on.

Don't they typically do local anesthetic for eye surgeries? I know at least some offices do for IOL placement.

Yes.

Risks for both contact lenses and LASIK are incredibly low, but with that said strictly from a quantitative perspective, contact lenses carry a higher risk of permanent vision loss than LASIK. The issue is that the risk of LASIK is almost entirely front-loaded whereas the risk from contact lenses causing an infection that results in significant to total loss of vision accumulates little by little.

does it actually accumulate (memory), or is it a Poisson process where if you go a day with good luck, you start fresh for the next and every day, same unaccumulated risk?

Including daily disposable contact lenses?

Sweet, thanks for the name of it, when I was learning more about it, I was trying to think of what this was called. I'm surprised it isn't more common like PSK/Lasik.

There's some interesting Infrared/LED light stuff coming out about eyesight repair too.
