Blepharoplasty and levator resection is the only facial surgery I've ever had, and it was for functional purposes mainly, so that I would have better peripheral vision, although I admit to a certain amount of vanity as well. The levator muscles of my eyes were torn......the surgeon said the muscles were weak, and that it was a congenital condition.
So, saying that, before surgery, I looked somewhat like Garfield the cat......and now, I don't.
Insurance covered the levator muscle resection, but not the blepharoplasty, which ended up being something in the neighborhood of $3500 out of pocket. I think insurance covered something like $4000 for the muscle resection. Get the best surgeon you can find. This is your face, so now is not the time to value shop.
Expect to look like you were in a brawl for about 2 weeks or so. You can invent a colorful story if you like. Use vitamin E oil on the area every day for several months.
