Uneven Eyelids/Eyes - can I get a treatment only on my right eye? (Photo)

My right eyelid is smaller and thinner than my left one, which makes my right eyelid more hooded. It is especially prominent when I smile. My right eyelid also appears more retracted.I don't think this is because of the muscle, because I think my right eyelid just has less skin/fat than the left eyelid. This is not because of ptosis or a disease, it was just because I rubbed my right eyelid too much. If I have to get surgery for this, I would only like an operation on my right eye.
