I Have Uneven Eyes. Is There a Procedure to Fix This? (photo)

My right eye is higher than my left. Similar to Shannon Doherty's, though maybe not quite as pronounced. But it bothers me... In fact, the whole right side of my face seems (to me, at least) very disproportional to the left. I've heard that how your jaw develops over the years and sets in your skull may affect this. Whatever the answer, is there surgery to correct this, and how much would it cost? Included is a picture of Shannon's eyes, and mine, so you get the idea.
