with that logic, losing an eye is a game changing event that has real and lasting consequences, except it doesn't really. Head canon changes and cosmetic changes are meaningless if the narrative doesn't respond to any of it.
Depends which one you mean because there are two such events...the consequence of one is actually pretty nasty while the other will have a positive effect although you will now have one eye that looks different from the other. But still not the same thing as complete facial mutilation.
