I did it in plastic surgery. It's been 4 years and I'm still happy with it. After the swelling subsided, I felt a little bit sad.. It was so natural that it was much better than awkward and strange, and my impression was changed. The manager was really kind and caring. He asked me if it still hurts when I pulled the stitches, and he made the front slit as wide as possible without really showing the inside of the eye. Some hospitals said that the rear slit was not necessary, but I did it because I wanted it so much. I definitely don't think the rear split has much effect .
