About 5 years ago, I had a lot of fat in my eyes, so I had a double eyelid surgery with a partial incision after removing the fat. He also had a front slit. I'm more satisfied than before, but now, 5 years later, my left eye has loosened up a bit (my friend who had surgery at this hospital only 2 years ago, but it's completely healed and I'm going to get another surgery). Anyway , in my experience, it seems that it takes a year for the swelling to completely disappear and become natural, and it seems to keep changing after that. My eyes are droopy than when I first started.
