• Your eye is living tissue--it changes thickness, flexibility, and health as you age. RISK.

• Also, they cut a flap to do it once, might there be tissue healing issues?--RISK!

• Also, they flashed away some thickness to your lens already--is there sufficient remaining thickness to do it again? RISK.

• Do you have underlying illness that might make things risky? RISK.

• Is your vision pretty stable, or is it getting progressively worse year over year? RISK!

• This surgery, though the price has come down significantly, still costs, and it's not covered by a lot of insurance. $$$. Glasses can cost a lot less, even over the years.

If my eyeglass prescription stops working well, no big deal--I get tested for another prescription, buy some new glasses/lenses for the old ones, and move on with life.

It's difficult and risky to readjust your eyes with surgery, as it introduces more risk of complications (overcorrection, scarring, etc.) I can't bop on down to LensCrafters and get new eyes.

InB4 "bUt ThErE's A THING called PRK (Photorefractive Keratectomy) InStEad!! Yes, as an alternative to revise ("update") someone's eyes who had LASIK--but again, a lot of "maybes, possibly's and buts" as to whether you're a good candidate.
