Edit: I forgot to mention but newer techniques for corneal transplant are within reach, and current techniques in the right hands are very successful at giving usable vision.
Best of luck!
Ability to grow any organ from stem cells, let alone as complex as an eye, is breathtaking development that up until now was basically Sci-Fi.
I don't have a lot of knowledge in the field, but I believe that once we learn how to grow one organ there isn't a lot than more hard work to learn how to grow other organs.
A woman has the baby, and the umbilical stem cells are collected, and put in a deep freeze. Instead of circumsision, that doctor would be more concerned about saving the stem cells?
Who knows what medical breakthroughs will come?
(I don't know much about stem cells, other than the political stuff associated woth them.)
From what I understand, though, stem cells don't last longer than a few years in storage. Making private banks a less useful.
(Or just farm fertilized eggs)
It would be quite an achievement though, because axons navigate their way by a gradients of some chemicals, which probably dissipate with age.
And problems will not end when nerves have grown. Brains would need to learn how to use them.
