    Dad: Arizona girl's corneas saved vision of 2 kids

    TUCSON, Ariz. – Donated corneas from the young girl killed in the Arizona mass shooting have saved the eyesight of two children, the girl's father told The Associated Press on Monday.

    John Green said the Donor Network of Arizona told him and his wife about the successful transplants.

    He said he doesn't know whether any of 9-year-old Christina Taylor Green's other organs have gone to any other children, but he's under the impression that her wounds rendered her internal organs unusable

    how is this done? could you explain it to us lay people? how can someone's cornea work in someone else's eye? a heart transplant makes sense, as it is more like an engine, but a cornea...?

    The cornea is the thin transparent film that covers your pupil. In some situations, this can lose it's transparency, either through disease or trauma. If the cornea becomes opaque for too long (especially in a child), vision can be permanently lost.

    As far as I know, corneas are the most transplantable part of the body. Because they don't really have much of a blood supply, they are not as quickly effected by the anoxia of death. And I believe that they are not as likely to be rejected by the recipient like with other organs, due to the fact that they don't have a significant blood supply.

    Nearly everyone can donate their corneas at the time of their death. Only those who die a brain death can donate their vital organs. A cardiovascular death results in too much anoxic damage to organs.

    thank you.

    it amazes me that you can take someone's "eye" (a dead person's eye) and transplant that into a living person and that living person will see due to the dead person's eye.

    Well...it's not quite the dead person's EYE that is transplanted. Just the thin clear layer over the pupil.

    The area that is transplanted is probably the size and appearance of a contact lens.

    If the rest of your eye (pupil, lens, retina, optic nerve) is fucked up, you are fucked.

    Still that's pretty awesome that they could do that.

    RIP to the girl, though. :(

    At least there's a silver lining from the story.

    Corneas are clear, not silver.
