It's interesting, I was thinking about this just the other day because I have a friend with a blind autistic daughter... I wonder if it's easier to have once had your sight, and then lost it, than to be blind from birth. On the one hand, you have a memory of the way the world looks and kind of a mental map in your head, and that can help greatly with interacting with everyday objects. On the other hand, if it's from birth you've been honing your other senses from the beginning, rather than having to re-learn how to rely on them more intensely.
Either way, Kieran is awesome!
