My character has a prosthetic, or technically you could say a bionic or cybernetic, left eye. For one reason or another, the replacement eye couldn’t be connected directly to the optic nerve. Instead, all of the visual system for the left eye has to be replaced (optic nerve, optic tract and such) with wiring or something similar.
How would this surgery procedure go and how would they connect these new parts of the visual system to the brain to allow the new eye to function as well as the original?
The answer should be purely ‘mechanical’ in nature, as in none of this future ‘biotech’ or things were organic components can just be manipulated so it ‘just works.’
Edit: Future technology is fine, necessary even. The future tech i'm asking to be not included is things like fully grown organic replacements, nano-technology, or bio-engineering of the human itself.
