And to be fair, we've never seen any healing technique restore sight to a blind Mangekyo Sharingan. Healing Power (which is said to be a product of Hashi's Cells) didn't even restore the vision within the blind Sharingan within Danzo's arm, so I doubt CR or the BS would do so.

Another thing, Naruto restored Kakashi's missing eye completely, but couldn't completely restore functionality to Guy's leg after healing it - Some things just can't be healed I guess. sorry to be going off topic but more then likely for guys legs it has something to do with the opening of the 8th gate and how basically its called the gate of death for a reason, it is meant to kill the user, so more then likely it is similar to the Mangekyo's blindness except it can be stopped from dying, but at the cost of the most damaged parts of your body not being able to get healed, Guy's battle with madara broke a lot of bones, but the most severe in my opinion where the bones in his legs as it seems he shattered the bones in his legs. that is just my own personal theory but its something.
