Even after several surgeries you may be able to improve things.
It is hard to know without pictures and a complete history exactly what has transpired and what you might need. You need to make sure you see an oculoplastic surgeon at this point, as they will give you the best chance for a successful outcome. You want to make this your last surgery!
However, without a personal examination, it is impossible to know what your issues are and what resources are left for reconstructing eyelid function. I would recommend a great deal of caution if you are considering additional surgical work. It is very difficult to unstir the cream from the coffee. You need to find eyelid reconstructive surgeons who really know what they are doing.
