I took a LASEK surgery in Gangnam clinic a few months ago and I am extremely happy with the results. I feel like my eyesight has never been this good in my life. I am so glad to be able to say goodbye to my glasses and contact lenses. The staff in the Dream eye center is really professional and kind. They always take a really good care of me and stay in contact regularly. Many of the doctors also speak good English, so you don't need to worry about communicating. I highly recommend this place to all other foreigners who consider taking an eye surgery!
