Some asymmetries can be fixed, others cannot.
Often, one globe (eyeball) is more deeply set than another. That means that it sits more deeply in the bone of the eye (orbital socket). This in turn causes many other asymmetries. The deeper eye will have more laxity (looseness) of the overlying skin, causing the upper eyelids to appear different.
There is often on the same side as the deeper set eye a flattening of the cheekbone, again causing the eye area to look different. There may be an orbital dystopia, where the eye bones are actually at different levels.
Brows can be at diffferent levels, or have different strengths of muscles functioning to cause the brow to appear different. The whole anatomy of every bone and muscle in the face comes into play.
Differences in the set of a globe cannot, for practical purposes, be corrected. However, a plastic surgeon who carefully analyzes the asymmetries of the face can come up with a plan that minimizes the asymmetries.
Nobody is completely symmetrical. A skilled and artistic plastic surgeon can point out the asymmetries and come up with a plan to minimize them. He or she can also point out which asymmetries cannot be fixed. You should feel comfortable after your consultation that your asymmetries were pointed out, recognized, and a plan included how to reduce the fixable asymmetries as much as possible.
Overall, asymmetries can often be minimized, but never completely removed.
