Please recommend a place that does LASIK or LASEK surgery well.

I live in Seongnam, Gyeonggi-do.

I'm looking into LASIK or LASEK surgery for my older child. Seongnam, Bundang, and Gangnam are good options. If you know of a hospital that's good at LASIK and LASEK surgery, please recommend it to me.

If there is anyone who has had surgery, could you recommend where it was done and how much it cost? I would be grateful.
