This is interesting! I recently read that new tech has also allowed PRK to become better and thus more popular again - I compared it to LASIK a while ago and would probably have leaned more towards PRK from what I read.
This looks like the best of both worlds, great idea.
I got PRK last year because I didn't want the flap. I was supposed to have 20/20 or better vision after a month. Exactly one week later, my eyes had recovered to 20/15 and 20/18. The recovery honestly wasn't that bad and I forget that I've only had perfect vision for a year. One of the best investments in myself I've ever made!
