Is there a connection between eyelid contractions and ptosis?

I have suffered with chronic eyelid contractions for many years. May are uncomfortable sensations of my eyes wanting to open wide. These are not twitches, although I get those too. Years ago the right eye stopped spasming and i developed a ptosis. I just had it corrected 5 weeks ago then the left eye drooped, but stopped spasming. I plan to have to fixed when I can.
