Over correction after ptosis repair. What are my options? (Photo)

While both of your eyelids are within the 3-5 mm average for margin to reflex distance that is expected, your right upper eyelid is higher than the left. One option would be to lift the left upper eyelid slightly (1 mm or so) which would also have the effect of slightly lowering the right upper eyelid. This effect is called Hering's law. This would likely be the simplest and most cosmetically beneficial option, but you should discuss it with a trusted provider who has performed a thorough examination of your eyes.
