Prosthetic eye to treat blindness

It maybe official.  I think I am a TED video junkie.  Here is one (hat tip ScienceRoll) that describes how researchers are developing a prosthetic eye to treat blindness.  Take the time to watch the whole thing because it is fascinating.

This is the very kind of biotechnology that we Catholics should support.

But beware! The transhumanists will claim these advancements for themselves. They will say this prosthetic eye is just one more example of how transhumanism, the movement that seeks to use technology to make ordinary man "post human," will make all of our lives better. Except this prosthetic eye is not an example of transhumanism. This is an example of medicine, taking technology to restore a normal human function. Transhuman literally means "beyond human."  So the transhumanist does not just want to restore normal function, they want to augment or replace it.  So once the technology is good enough that the digital images are as good or better than what the normal human eye can see, the transhumanist wants such prosthetics to replace their eyes that can see perfectly well. 

We can embrace ethical technology where the intent is to cure or reconstruct.  Once the technology passes into the realm of enhancement of the otherwise healthy, it is no longer medicine and becomes something else entirely.
