Dream eye center in Gangnam is THE place to be if you want to get laser eye correction. The location is in one of the most affluent areas of the city and the staff is very foreign friendly. Although the center may be a bit pricier than some, it's worth it if you want the job done right. You do have to go back frequently to get your eyes checked but it's important to prevent infection. If you get a staff member named Young Jin, he's the best and he'll take good care of you.
