Uneven eyelids. How can I treat them?

At times my eyelids are uneven. Sometimes it's one eyelid that raises a LOT more than the other. Sometimes it's the other eyelid that sinks a touch. Sometimes they're even. I've gone to many plastic surgeons and a oculoplastic surgeon who all have varying ideas about messing with the static lids or the eyebrows that move them. I know it's the muscle, so I shouldn't do anything that makes a static change. I've done Botox on the one eyebrow that makes that lid raise but it only helps mildly.
