I'm actually having Advanced Surface Ablation which is pretty much the same thing as LASEK or custom PRK but w/an alcohol solution instead of the brush to remove the epithelium. The doc's office I'm going with said that since the epithelium is devitalized once they take it off the corneal surface, replacing it doesn't really help recovery so they just remove it completely instead of setting it to the side and replacing it once the ablation is done.
On a side note, they said (and quite a few of the other surgeons I spoke with as well) that they're trending away from doing LASIK towards ASA. ASA's slightly longer recovery time, in their opinion, is offset by the safety that comes from not having to cut a LASIK flap and the fact you can do it on thinner corneas.
