Yep, I have two transplanted corneas, from ~25 and ~30 years ago. No anti-rejection medication needed after (IIRC) 12 months, unlike every other organ, where you need it forever. The cornea (the clear window right at the front of your eye) isn't connected to a blood supply, and gets its oxygen from tears. https://en.wikipedia.org/wiki/Corneal_transplantation https://en.wikipedia.org/wiki/Corneal_transplantation
- lproven 3y agoYou're right about the blood supply, but it gets oxygen direct from the atmosphere, not from tears. https://www.wtamu.edu/~cbaird/sq/mobile/2015/06/25/are-there-any-parts-of-the-human-body-that-get-oxygen-directly-from-the-air-and-not-from-the-blood/ https://www.wtamu.edu/~cbaird/sq/mobile/2015/06/25/are-there... This is why people with corneal transplants must be very cautious about wearing contact lenses.
