Another consideration before eye surgery: It is common to lose one (or even two) lines of best corrected visual acuity (BCVA). This is due to the damage the surgery does to your cornea, and has nothing to do with refractive error (which is improved with surgery).

BCVA is the best you can see with or without glasses. Someone who has a BCVA of 20/17 and uncorrected 20/100 might get surgery and then be able to see 20/20 without correction. But note that this guy LOST one line on the chart...he used to be able to see 20/17 with glasses but he has lost that forever.

If you have an interest in civilian commercial flying keep that in mind, you need to be correctable to 20/20 in EACH eye individually. If you are 20/10 BCVA now, you have some wiggle room, but if you are 20/20 BCVA then the surgery may well take you out of bounds.

I think I was 20/10 at your age, 20+ years later I'm about 20/15 or 20/17 BCVA. So keep in mind that you may lose a little with age, and on the civilian side you need to make it to age 65
