Did Levi Lose His Eye?

After a close-encounter explosion from a Thunder Spear set off by Zeke Yeager, Levi now has several scars across his face including one across his right eye and is missing both the index and middle fingers on his right hand.

Is Levi permanently disabled?

His injuries leave him permanently wheelchair-bound and he is attended to by Gabi and Falco." You can change it for example to "Three years later, we see Levi in a wheelchair (possibly due to severe injuries), with Falco helping him and Gabi, and Onyankopon walking in front of them."

Does Levi fully recover?

As a result, the Thunder Spear exploded, catching both men in a huge and volatile explosion. Being a Titan shifter, Zeke eventually heals and comes out of the blast uninjured. However, being purely human, Levi has severe injuries that cannot heal instantly like Zeke's.
