I had my upper eyelids done ten years ago at age 49. I chose an ocular plastic surgeon, because all he works on is eyes. He's the person people go to when their surgery has been blotched.
Ten years later, I am still very happy with the surgery. It made more of a difference in my appearance than anything else I've had done. He made my uneven eyelids symmetrical, and the tired look continues to be gone.
For me, it was well worth the money. The critical variable is the competence of your surgeon. Do your research before choosing a doctor.
