Eye not closing fully - any suggestions what is causing this? (Photo)

I had upper blepharoplasty and one of my eyes is not fully closing from day 1 PO (over 12 weeks now). What I’ve noticed if that if I “help” the lid with my finger to close it will stay closed. Also, some days the opening is wider and other days it almost non-existent. My doctor said she doesn’t have any explanation why it happens. Meanwhile I have to keep moisturizing the eye otherwise it starts to hurt. Any suggestions what is causing this? I’m considering finding another oculoplastic surgeon t
