Like last night they “reported” at least six times that they would show us in a hour how “a woman regained her sight when they planted her tooth in her eye.” Pretty startling, all right. And I waited and tuned in, then felt ripped off when we find that sliver of tooth just props a plastic lens in place. Why a tooth and not a plastic prop? That was the true question, but the reporters were too dumb to ask it.
So why a tooth?
Chief Pedant gave an excellent answer to this one yesterday. There’s also some more info in the articles linked from the thread.
I’d give my eyeteeth to know.
