On the subject of ortho-k and the new technique called corneaplasty being detectable. I was told by a Doctor who specialises in orhto-k that it is detectable but only if they go looking very hard for it and even then some eye docs will say yes you have had it and some will say no.
In case any one is wondering Corneaplasty is a new technique in development for refractive correction, it has many advantages over the laser based methods because it is non surgical and has significantly reduced side effects.
Here is a link that explains it all
