I would like to inquire about restoration of the mucous membrane of the opening.

It's been 4 years since I had a posterior epicanthoplasty... I
 heard somewhere that a posterior epicanthoplasty is a surgery to remove a window frame, so I should never have had it, but when I
 heard that our hospital has new technology and there are absolutely no side effects, I really regret doing it out of a desire to enlarge my small eyes. I'm angry at myself...
 I also have dry eyes, so I'm using disposable artificial tears 10 times a day... Eye mucosa? I have really bad dry eyes because my skin is separated from my eyes.
 About 3-4 months after the surgery, I went to look into a lot of restoration surgery, but I was told that it would be difficult to completely restore it to its original state, so I gave up and just lived with it, but
 these days, I'm looking into restoration surgery again. Is there anyone who, like me, had an opening and was restored with a raised mucous membrane?
 If so, I would appreciate it if you could give me even a little information.

If anyone reading this post is thinking about getting a rear flap, don’t do it! This is truly the choice I regret the most in my life.
