No. We don't need "Yang Release: Eternal Izanagi Super Over The Top Infinite Death Avoidance Etc no justu".

Honestly I'm not so sure. This isn't just a damaged organ, you're basically using that eye as payment for the technique, so it's not just bodily damage. For all we know, the chakra to the eye or the eye itself is sealed away. So far the only healing observed was to physical damage (Gai's body tearing itself apart. Kakashi's long gone eye.). It has been stated that Naruto has limits on his healing as well anyways.
