I got incision-based eye correction because it was famous on a Naver men's fashion cafe. The amount of black iris showing differed between my eyes, and my double eyelid line was also thick, so I am now looking into revision surgery.
In particular, when I visited for the purpose of revision-surgery consultation, I felt that the aftercare was lacking. Over the past few months I visited about 10 plastic surgery clinics in Apgujeong, and they commonly recommended lowering the incision line plus eye correction, but here I was told there was basically nothing they could do except Botox.
I did see people who had good results here, but I feel my own experience did not go well, so please take this as a personal account and use it only as a reference when deciding.
