I've seen a number of cases where a LF1 actually did improve the under eye area. It perplexed me too. There's two ways it happens I think. First, the shelf created by the LeFort provides some support for the tissue above. Second, more significantly, the MMA creates more volume in the face stretching all the skin around it. Eyes... there's no winning it I think. I've got a post coming but I think augmentation some day is a reasonable approach here. I don't see why they can't do it with BMP2 today even, just no one has tried it. Go under eye and avoid the whole mid-face mess of muscles and nerves. Even the modified LeFort 3 avoids some of the critical region btw, this is a very hard problem to solve otherwise.
