Groundbreaking: First-Ever 3D-Printed Cornea
Implanted in Human Patient
Introduction
In a major
advancement for regenerative medicine, a patient suffering from legal blindness
has successfully received a 3D-printed cornea made from living human eye cells. This
unprecedented procedure marks the successful beginning of an early-stage
clinical trial, according to the implant manufacturer, Precise Bio. This
breakthrough offers a potential solution to the critical global shortage of
human donor corneas required for standard transplant operations.

Restoration
The procedure
involved implanting the bio-printed tissue, a significant step forward from
current medical practices that rely solely on tissue from human donors.
Commenting on the
milestone, Dr. Michael Mimouni, a surgeon at Rambam
Medical Center
in Israel,
stated:
- "For
the first time in history, we witnessed a cornea produced in a lab, from living
human cells, restoring sight to a person. It was a glimpse into a future where
no one will have to live in darkness due to a lack of donated tissue."
Overcoming the Global Donor Tissue Crisis
Current corneal
transplantation procedures are hampered by the constant deficit of available
donor tissue. Demand for cornea grafts frequently surpasses the global supply,
leading to long waiting lists for patients with corneal diseases.
- Researchers involved
in the project emphasized that the 3D bioprinting process dramatically changes the supply dynamic. The
technology allows for the in-vitro development and production of hundreds of viable grafts from the cells harvested from just a single human
donor cornea. This scalability is key to addressing the widespread shortage.
Phase 1 Trial Details and Future Outlook
The ongoing Phase 1 trial
aims to evaluate the safety and efficacy of the implant in its initial stage.
·
Trial Scope: The current phase involves implanting the
3D-printed cornea into a total of 10 to 15 patients.
·
Company: The implant was developed by Precise Bio, a company headquartered in North
Carolina, USA,
with established operations in Israel.
·
Timeline: The company anticipates announcing the
preliminary results of this landmark study in the second half of 2026.
This
development heralds a promising future for millions suffering from corneal
blindness, potentially replacing unpredictable donor-based supply with a
scalable, manufactured solution.
