I had double eyelid surgery in 2008, and as time passed, my eyes looked a little stuffy and reoperation was burdensome, so I looked into bottom opening + back opening. I was worried because there was talk of it coming back together and there were side effects such as redness under the eyes due to excessive opening, but I am completely satisfied!! There were no side effects at all, and during the recovery process, the whites of my eyes became filled with water, but I recovered in 2 weeks. Everyone who saw me said that my eyes got bigger, but they didn't even notice that I had a posterior epicanthoplasty and epicanthoplasty :)
