I had surgery as a middle schooler 8 years ago. I got ptosis correction because I was told it would improve sleepy-looking eyes, but it didn't help, and my epicanthoplasty left a white scar... There is also distortion of the aegyo-sal, and it has been a really huge source of stress even now..
Also, my eyes were uneven, so I had revision surgery on only one side, but during the operation the director said that my eyes themselves were different on each side... and that I might need to lose some weight, which left me very flustered.
