The first surgery I had as soon as I turned 20 had very thin lines and was almost at the level of a double eyelid, so after 7 years, I received a double incision, eye correction, and 4D canthoplasty at a hospital specializing in revision surgery in Busan. However, the lines were even, and white scars appeared in the front epicanthoplasty, and the posterior epicanthoplasty was okay on the left, but on the right. My eyes have improved a lot compared to the first surgery, but I am a little disappointed that it is not a 100% satisfactory surgery.
