Unfortunately surgery can also injury an eyelid and create ptosis. This really occurs in eyelids predisposed to develop ptosis. It seems that the surgery accelerates things. You honestly need to let this eyelid heal. I would not consider surgery until you have let the eyelid heal for 6 months. There is the possibility that the eyelid position will improve. I just think this is improbably. The main reason for giving the eyelid time to heal is that it seems to improve the accuracy of the revision surgery you will likely need.
