Could it be possible that I need a third ptosis surgery? (Photo)

It is simple but it is often associated with under correction of the eyelid position.  The fundamental problem here is that in order for the Muellerectomy to be successful, the levator aponeurosis needs to be in position over the tarsus.  In many eyelids, like yours, that is not the anatomic situation.  In these eyelids, the central levator aponeurosis is disinserted.  It is not in position to respond to the surgery which plicates the levator when the levator normally inserts into the tarsus.  This is not the case for central levator disinsertion.  The Mullerectomy fails because it is unable to plicate the levator that is not in the right position. Unfortunately many ptosis surgeons are not familiar with this research. The answer is to correct this eyelid using an anterior levator ptosis surgery.  I don’t think your surgeon gets this.

Revision ptosis surgery is a complex procedure that is usually best done using a special technique but consultation is definitely necessary to determine that.
