I had a heart attack and now my left eye droops considerable and my right eye is wide open. How do I fix this?

If you had a neurologic deficit causing drooping of your eyes after a cardiac event, you may also have had a stroke. You should be evaluated by a neurologist to find the cause of your eyelid drooping. This does not seem to be a primarily cosmetic concern. After a neurologist confirms your neurologic status, then I would recommend you consult a facial or occuloplastic surgeon for your eyelid repositioning.
