On rare occasions, a unilateral blepharoplasty can be performed. A full set of photographs and an in-person examination are required to make that determination
It is very unusual to perform unilateral blepharoplasty. The angle of your photo makes it difficult to asses the difference between the right and left upper eyelid. A frontal full face photo would be more helpful. On preliminary review it looks like your eyebrows are at different heights. This can contribute to the difference in the eyelids. I suggest an evaluation by an Oculoplastic surgeon in your local area. Vikram D. Durairaj, MD FACSAustin, Tx
