My younger sibling had eye surgery about a month ago. It was done with the buried suture method, and the cost was around 1.2 million won. It was done at a plastic surgery clinic near Apgujeong Station that an acquaintance recommended.
Their eyes were not originally big, so they said very large eyes would not be possible even after double eyelid surgery.
Maybe because of that, it just looks like a double eyelid line formed above the eyes Still, my sibling seems satisfied.
The swelling still makes it obvious that they had surgery.
