There have been some people who've gotten their eyesight back after being blind once they were fitted with a bionic eye.
However it's rare for a person that is blind to be able to see again and usually an eye transplant will not work to regain someones eyesight since the blindness is related and caused by a problem with the eyes nerves.
Unless some Miracle happens then a blind person is likely to not be able to see again but may in some cases.
