I had PRK back in Dec 2005. Tripler AMC in Hawaii. Well worth it. Within a few or so I remember driving under the H1 bridge and being able to see damn near all the way to the end. My vision was 20/15 in one eye, 20/12 in the other. I was 20 years old at the time...now I'm 28 and my vision is back to where it used to be. Around 20/70 - 20/100. As eyes age, vision will get worse. The doc did a great job. Unless I tell an optometrist I had PRK,they would never know, no scars or any evidence that it was done (so they tell me).
