Is Advanced Surface Ablation the same treatment as Transepithelial Photorefractive Keratectomy? In what do they differ?

I hear some eye docters say they dont do PRK no more but they only do ASA now. (which is an advanced PRK method?) Here in the Netherlands there is noone that does ASA, but only TRANSPRK. Are they one and the same or is one better (newer) then the other? (i want the best of course for my eyes, least chance on haze complications etc.) Hope you can answer this for me, Thx Marcel
