I had it done the year before last: epicanthoplasty, incisional double eyelid surgery, and ptosis correction for 1.6 million won. I can't quite remember whether fat removal was done, but my eyes did become a little sausage-like. That might also be because my skin is thick. Hehe My eyes are almost the same as my dad's, and since even when my dad got older his eyelids never really hollows out, it's probably just because my skin is thick... lol There was no excessive estimate, and even though it was a full incision, the scar was not severe. The line was also shaped quite well.
However, on the day of surgery my older sister went with me, and since she has a much more obvious monolid+small eyes than I do, they recommended double eyelid surgery to her two or three times. lol They said they would make her look pretty...
