A really lame question regarding The Tower ending.

So, if V’s brain is supposedly “deaf” to cyberware, how exactly do they see? We know V has kiroshi’s, so how do they continue to see if their body doesn’t respond to cyberware? Shouldn’t the eyes just shut down and stop working, or can they still handle basic cyberware such as that? My current theory is that kiroshi’s are directly connected to the brain, unlike something like gorilla arms.
