Hey I had a bit of a stigmatism and I had terrible vision. Now I am seeing 20/20 or 20/15 ish. Get the surgery. The only time you have to worry about complications is if your cornea is too thin or you have some type of issue with your nerve endings. I would go with Lasik as well. It is approved by Navy, hurts a hell of a lot less, and you start seeing better within 3 hours after surgery (not kidding). I had thick corneas and PRK would have been fine but my eye doctor said just go with LASIK. Its cheaper, you heal faster, exact same results, and it is approved by military. Dont worry about people who dramatize about flaps becoming undone, that happens very rarely and usually because of a shitty doctor or you did not follow through on post op procedures. It is on you to find a great doctor to perform the surgery. I found one of the best in Arizona and had no history of anything dramatic happening with his patients and was rated one of the top eye surgeons. Also the guy was cool and I felt good vibes form him. For SNA you need the 20/20 and MEPS is not going to have you squint. Stop wasting your time in hoping you can exercise your eye muscle or worrying about over correction. The machines used are so sophisticated you wont have to worry about it. It is worth the money. Go see an eye doctor first to give you the low down and do all the pre work (measure how thick your corneas are, your current eye sight, along with other measurements, health of your eye). He can explain everything to you and give you an honest assessment.
