I had revision double-eyelid surgery at Ibon because of asymmetry and low crease height. To get the in-out line I wanted, they said I would need epicanthoplasty, so I had partial incision, epicanthoplasty, and ptosis correction.
Since my eyes had already been incised before, I wondered if partial incision would work, but even right after surgery both sides had the same line, and after a month the in-out line I wanted came out, so I am very satisfied!
During surgery they made me close and open my eyes dozens of times, and they also put in contact lenses to protect my eyes, which was nice.
I had also gone to Ibon when I was scouting places for my first surgery, and the only regret I have is not having the surgery here then!
People around me also said it turned out well haha
