How would you treat asymmetrical Asian eyes to get natural results? What needs to be done to each eye?

Thanks for sharing your photos.
Your right eye has mild ptosis which causes loose and wider crease compare to your left eye. This need to be corrected at the same time when you do create crease. Phenylephrine eye drop test will be helpful to achieve the symmetrical crease prior to actual surgery.

Right upper eyelid ptosis surgery can improve the upper eyelid asymmetry since there is right upper eyelid present. Skin removal (upper blepharoplasty) can be added based on desired goal of how much crease to show. Need evaluation in consultation.

Morning,You have ptosis on the right eyelid and the left appears fine.  I think the smartest thing to do is a ptosis repair of the right eyelid and crease creation with anchoring technique at the same time.  You appear very young so it might be best to leave the left eye alone if you can, particularly since you want a "natural" appearance.  Now what a person means when they say Natural or Asian is subjective and is specific to that person. What you really need to do is talk to a specialist in ptosis and Asian eyelid surgery and see what that surgeon has to say.In my case I perform both the surgeries together, daily.  I'd likely advance your right levator tendon and utilize anchoring technique to match the two eyes.  It would take about 10 days to look decent and 2-6 months to start to see the final result.Best of luckChase Lay MD
