Would I be a better candidate for unilateral blepharoplasty of my upper right eyelid or bilateral blepharoplasty? (Photo)

Even though you notice the right eyelid more than left you should have bilateral blepharoplasty. Your surgeon will just remove more skin from the right eyelid than the left giving more symmetry and a maximum result.
Good luck! 

Thank you for your question and the detailed photographs witht he different positions - was that a very steady hand or someone helping you with the photos !!The main question is does your right eye bother you? If it doesnt then a unilateral bleph is possible. You would have a scar on one side compared to the other. The eyes would be more symmetrical in their appearance but no one could guarantee getting them completely symmetrical as it is a couple of mm difference currently which would then need to heal with scarring. It is easier to do a bilateral as both eyes would then have scarring and behave in a similar way. But either way is possible and to answer your question, yes you would be a candidate for a unilateral blepharoplastyI hope this is helpful for youKR

Thank you for your question. Sometimes a unilateral blepharoplasty (eyelid lift) can be carried out in some cases of mature patients where a degree of ptosis (drooping) is impairing the visual field in one eye, sometimes these patients require a bilateral blepharoplasty, and almost always this type of procedure is covered under insurance. However, when a younger patient has concerns of excess skin and fullness that fall more inline with a cosmetic concern and not affecting vision, then it is usually advisable to perform a bilateral cosmetic blepharoplasty (eyelid lift) to maintain a balanced and homogenous look overall.Undergoing any surgical procedure requires careful attention to detail and consideration for different options.  Consider obtaining several opinions before moving forward with any given procedure.
Trust your face to a board-certified facial plastic surgeon or a board-certified plastic surgeon with very extensive blepharoplasty experience.
