Had bilateral ptosis surgery 5 months ago. Right eye healed and looks perfect. Left eye he been majorly falling behind and is not behaving like my right eye lid at all. I can feel muscles trying to pull yet my eye lid doesn’t open well. The lid itself you can feel it’s more full / puffy than the right and I have a very small lump that has taken ages to go away. My surgeon doesn’t know what to think as to why it’s taking so long.What’s wrong?
