Ok guys.......
On the basis of my experience.
in UK (Gatwick) I did not saw any computer to do Corneal mapping and they did not any special examination at my cornea.
So I assume if you don't tell them nothing they are not able to find the laser intervention.
But Lasik and other laser corrections are allowed, if you are inside limits before the intervention so why don't tell them?
Since laser is allowed, is better to admit about the intervention because before practice the visit, you have to sign a paper with your story and there is explicity a question :"Do you had any lasers/lasik intervention at your eyes"?
If you declare NO, you do a false declaration....I don't know what happen.
And even if you pass your initial and in the future will emerge you did laser, should be a BIG BIG problem. Much better tell them as first thing.
I did my laser (RPK) 8 year ago, and no problem at all: 1 class no restrictions.
When you do laser, clearly before the laser intervention, the doctor write your clinic state, included pre-operative myopia and astigmatism: AME will want a copy of this paper. Thats all.
