Subject: Is there a possiblility of installing chips in the human eye to see again?

My father became blind in the past five years. His doctor explained to me that 
his eyes are good but the nerve that relates the eye to the brain in not good. 
I want my father to see again so bad that I can accept that he goes for 
clinical trials if suggested, provided it does not cause further harm to him. 
Do you have any recommendations or answer to the fact that some chips could be 
installed in his eyes to relate the image to the brain so that he can see 
again? Thanks
