A revolutionary device that revives donor eyeballs could make eye transplants a viable option for restoring sight, according to researchers. The Eye-in-a-Care-Box (ECaBox) uses perfusion techniques to maintain and revive eyes removed from the body.

The device delivers an oxygen-rich supply of fluid through the eye's blood artery, allowing it to remain functional. In tests, pig eyes kept in the ECaBox retained their ability to respond to light after 15 minutes, suggesting they might see if transplanted. Human eyeballs showed similar improvements.

The technique could significantly enhance the viability of donor eyes for transplantation and offer a new avenue for studying eye treatments without using live animals. However, the team acknowledges that further testing is needed before the ECaBox can be used in clinical settings.

Shannon Tessier at Massachusetts General Hospital calls it 'really cool' and sees potential as a 'new frontier for retina preservation'. While the technology shows promise, there remain challenges to overcome before full-eye transplants become a reality. For now, the ECaBox offers hope for those awaiting sight-restoring surgeries.
