A place in Gangseo-gu, Seoul that does a good job with Smile LASIK

Please recommend a good place for Smile LASIK in the Gangseo-gu area of Seoul. Most people say they get LASIK in Gangnam, but I don't have time to take my child there. I don't know much about it either, and I'm worried about being overcharged, so I want to do some research before going.

I'm worried that if I go to find out, I might end up making a reservation and coming backㅠㅠㅠ It seems like many places do well, but I can't tell which one is good... When deciding where to go, what should I use as the criteria for making the decision??
