I recommend Yeongdeungpo Kim Eye Hospital.

Yeongdeungpo Kim Eye Clinic is already quite famous, isn't it? A coworker of mine had cataract surgery at a general hospital, and he said his satisfaction with the clinic improved dramatically after transferring to Yeongdeungpo Kim Eye Clinic. He said general hospitals are too complicated, so if he ever needs an ophthalmologist, he should come here. He said the staff is friendly and trustworthy.
