I'm not sure about the HKG clinics, I had mine done in Australia.
In answer to your PM:
LASEK is when they drop a chemical in your eye which loosens the top layer of cells on the cornea. They scrape this layer to the side of your eye. It looks like someone has put a piece of glad-wrap on your eye and scrape it to the side. The laser then does it's work, they move the layer back into position and it heals in a week or so.
LASIK is when they slice a layer of the cornea making a sort of flap. They peel the flap back and let the laser do it's thing. Put the flap back and you're right to go. LASIK heals faster (they say you can drive home from the procedure) but there can be complications in the healing process as there is an incision in your cornea.
Both procedures have their pros/cons, and it depends on what your problem is with your eyes (short/long sighted, astigmatism etc) as to which procedure is better suited.
