About 5 years ago I had an initial, and a revision ptosis surgery. However, as a result, the eye was left with an extra upper eyelid fold and in asymmetrical in relation to the other eye. I believe this may be due to the above area being too hollow. Would filler in the area create more volume to help pull (and hide) the double eyelid back into place? If so, how long does this last? If not, what are my alternatives?
