This is always a weird one I'm afraid. The JAA seems to change its mind a bit on this and usually appears to waiver towards the most conservative view.
They accepted PRK etc for PPL's and the like and then banned it for all new JAA initial issue class 1 medicals (although existing licence holders are still OK - logic?). This despite most of the rest of the world becoming more accepting of it.
The FAA had no problems with it at all, neither did the Australian CASA or the New Zealand CAA , etc, etc.
However being recently they went back to accepting it for both class 1 & 2. Common sense as significant numbers of people are having the PRK or LASIK procedure and odds on some pilots have already had it on the "sly".
I ask, would you rather have someone with great unaided eyesight in the other seat or some old geezer with thick bifocals that scatter everything at night, fall off at the worst times etc.
And yes I've had the PRK, 8 years ago - its been great. Unaided 6/5 eyesight an unrestricted class 1 medicals ever since.
The best info I can give you is check out the FAQ Medical section of the UK CAA website. It has the latest.
Hope things work out for you.
