If you are planning to go to Korea.. then just try to consult with 3~4 hospitals instead of pre-determining everything even before you go.. I also had some friends who went to Korea.. I was with them going around different hopitals for consultation.... If you want I can try to check some hospitals.....
I have a friend who recently went there for surgery....
She actually got some help from her friend in Korea...
if you want I can ask her about the surgery...
of ask her to give you some advise too.
