That's pricing the risk that it messes up your eye at zero. I don't think that's the right way to go about it.
I don't recall the exact numbers, but the risks were sufficiently tiny that I was not concerned about them. Anything that laser eye surgery can do to the outer layers of the eye I fully expect to be fixable in the ~30 year future before age-related eye issues become a problem for me. A great deal of the remaining "messes up your eye" scenarios are fixable by the surgeon. The truly horrific stuff means a malpractice lawsuit (or settlement under threat thereof).
I did some more reading on the risks from the website and handouts from the place I got my eyes done. 7% have their eyes over or under corrected and get re-correction in the first year. Serious complications are much more rare.
It goes without saying that you should do your homework and go to the best place you can find.
Persistent dry eyes is probably the most significant risk. Sounds minor, but isn't.
On ChrisHallquist's post extolling the virtues of money, the top comment is Eliezer pointing out the lack of concrete examples. Can anyone think of any? This is not just hypothetical: if I think your suggestion is good, I will try it (and report back on how it went)
I care about health, improving personal skills (particularly: programming, writing, people skills), gaining respect (particularly at work), and entertainment (these days: primarily books and computer games). If you think I should care about something else, feel free to suggest it.
I am early-twenties programmer living in San Francisco. In the interest of getting advice useful to more than one person, I'll omit further personal details.
Budget: $50/day
If your idea requires significant ongoing time commitment, that is a major negative.
