Eyelid Surgery Failure from Myasthenia Gravis?

I have mysathenia graivs. My doc did a lid lift in hopes to help this. It did not. I had a lot of complications. I still have droopy lids.What do we do now to fix this? I assume it is the muscle that lifts the eyelid. I could not open my eyes for 7 days after the surgery, and it was not due to swelling.I really would prefer to work this out with the doctor and let him fix this. I think the problem is the levator muscle of the eyelid but not sure if Mysathenia Gravis is the cause. How do we fix it? I feel so betrayed.
