I recommend Haengdang Seongmo Eye Clinic in Seongdong-gu for its thorough treatment!

Hello, I have been going to this hospital for a long time. It is good. The doctor is kind and looks at me very thoroughly. It is an old ophthalmology clinic in Haengdang Station and I have been going there since I was young. It is not a quick treatment but a thorough examination. If my eyes hurt or are severe, I go to the Haengdang St. Mary's Eye Clinic.
It is not as fancy as the recently opened hospitals, but it is a hospital that I keep visiting because of its very thorough treatment.
So, since there are a lot of people, the waiting time is a bit long, so you should leave plenty of time.
The waiting time is long due to the thorough treatment. It's hard to wait. But I recommend it.
