They told him it was science fiction: now the printed tissue restored people's sight

The Israeli company Precise Bio successfully implanted 3D-printed corneal tissue in five patients at Rambam Hospital, restoring their vision. The first transplant was performed in October 2025. The company, founded by physicist Arie Batt, plans to expand the trial to 15 patients.

The Israeli company Precise Bio, founded by physicist Arie Batt, successfully implanted 3D-printed corneal tissue in five patients at Rambam Hospital. The first transplant was performed in October 2025 on a patient who was blind in the treated eye and regained sight. The implant does not replace the entire cornea, but only the inner endothelial layer, responsible for draining fluids and maintaining corneal transparency. The technology may address the global shortage of corneas for transplantation. The company raised investment from medical equipment giant Carl Zeiss Meditec. The current trial is Phase 1, designed to test safety, with results expected in 2027. Batt notes that many previously called the idea "science fiction," and now there is proof the technology is possible. The company aims to eventually print heart, liver, and kidney tissues.
