Does ptosis normally get unacceptably worse throughout the day even after having surgery 6 months ago?

I had internal approach ptosis surgery 6 months ago on my right eyelid. The eyelid height is now ok when I wake up in the morning. 2-3 hours into the day the lid begins to droop a bit, but more importantly the eyelid crease goes higher. This leaves me with asymmetrical eyelids that look hallow on the left and a crease that is higher on the left for the majority of the day. I had this same problem to a greater degree before surgery. Is there anything that could fix this, possibly an ant approach?
