I would be very cautious about trying anything surgical. Based on the photo it appears that it is your left "eye" that is higher. While we can only visualize your upper face it does appear that it isn't just your left eye that is higher, but the socket, brow and face in general. Everybody has a degree of facial asymmetry, usually skeletal in origin. You will note that your left brow is also slightly higher. Having said that your lid creases, lid contour and upper lid fullness are beautiful and very symmetric. If you embarked on surgery solely to elevate the right eye so that it is even with the left, by building up the orbital floor for instance, it will change the relationship between the eye and the surrounding structures increasing the fullness in the right upper eyelid, producing asymmetry in the lid creases, and upper eyelids. It will also do nothing to make the brows more even. You have noticed relatively subtle asymmetry between your eyes / pupils as a consequence of overall facial asymmetry which we all have to a certain degree. Be very cautious about embarking on any surgery that could ruin the otherwise beautiful appearance of your eyes.
