I mean, yeah, you can do things for cosmetics.
But there's no optical difference.
NOW! Suppose you have a higher amount of prism loaded in ONE eye, only....the optics will be worse (chromatic aberration, etc.). So, sometimes, you may find an amblyope who is quite super-picky in their "good eye" and wants super-clear optics, and the other eye can't tell because it's not sensitive. In that case, hey, load up the crappy prism view in the crappy eye, if you want (presuming it's an adult)(presuming the cosmetics won't suffer).
In fact, in the one-or-two weirdo cases that I've seen where IT MATTERS that you put all the prism in one eye (instead of splitting) I wonder if it's not to "penalize" the lesser eye, in order to promote the dominance of the good eye. Hey, these people have messed up vision. It gets very odd. As we all know, vision = brain = perception = trouble!
