<p>From what I’ve read before, PRK is not a set in stone number based process. I’m sure there is some gray areas or exceptions or what not. There’s a lot of factors that go into the PRK process (as far as selecting who can and can’t get it) the specifics, I’m not sure of. What I have heard most CONSISTENTLY is that glasses are fine in UPT on… we still have some time for the details I suppose…</p>
