Unhappy with BA. Can symmetry be achieved with breast revision/correction?

I had my breast augmentation Dec 2015. I have never been happy with the results. I understand perfect symmetry cannot be achieved, however I have two very different breasts. My left upper pole slope is bulky, round and appears to be riding high in comparison to the right. My breasts are placed at varying distances from my midline and I have wide set cleavage. Right boob has a cone shape appearance while the right has a block appearance. Can the overall appearance of my breasts be improved with a breast revision/reduction?
