Surgeons at Rambam Eye Institute have made history by restoring sight to a legally blind patient using the world’s first 3D printed corneal implant derived from human cells.
In a groundbreaking medical achievement, surgeons at the Rambam Eye Institute have successfully restored vision to a legally blind patient through the use of a fully 3D printed corneal implant. This innovative implant was grown entirely from cultured human corneal cells, marking a significant milestone as it is the first corneal implant that does not rely on donor tissue to be transplanted into a human eye.
The process began with corneal cells obtained from a healthy deceased donor, which were then multiplied in a laboratory setting. Researchers utilized these cultured cells to print approximately 300 transparent implants using Precise Bio’s advanced regenerative platform. This system constructs a layered structure that mimics the natural cornea, providing clarity, strength, and long-term functionality.
The implications of this breakthrough are profound, especially considering the ongoing donor shortages that prevent millions of individuals from receiving sight-saving procedures each year. In developed countries, some patients may wait only days for a transplant, while others endure years of waiting due to limited tissue availability. The ability to create hundreds of implants from a single donor cornea could significantly alter this landscape.
Professor Michael Mimouni, director of the Cornea Unit in the Department of Ophthalmology at Rambam Eye Institute, led the surgical team responsible for this historic procedure. He described the moment as unforgettable, as the lab-grown implant successfully restored sight to a patient for the first time. “What this platform shows and proves is that in the lab, you can expand human cells. Then print them on any layer you need, and that tissue will be sustainable and work,” he stated. “We can hopefully reduce waiting times for all kinds of patients waiting for all kinds of transplants.”
This pioneering procedure is part of an ongoing Phase 1 clinical trial that evaluates the safety and tolerability of the 3D printed corneal implants in individuals suffering from corneal endothelial disease. The achievement is the result of years of collaborative efforts across research laboratories, operating rooms, and industry, demonstrating how coordinated teams can translate new treatments from concept to clinical application.
The success of this transplant will find a permanent home in the upcoming Helmsley Health Discovery Tower at Rambam. The new Eye Institute aims to consolidate care, training, and research under one roof, facilitating the transition from emerging science to practical treatment for patients throughout Northern Israel and beyond.
Precise Bio envisions that its 3D printing technology could eventually extend to other tissues, including cardiac muscle, liver, and kidney cells. While this future will necessitate extensive trials and validation, the path now appears more attainable.
For families affected by corneal disease, this advancement offers new hope. While donor tissue will likely continue to play a role in many regions, lab-grown implants present a viable solution to expand access where shortages hinder patient care. The success of this initial transplant also hints at a future where regenerative medicine could facilitate various types of tissue repair.
This milestone underscores the lengthy journey scientific breakthroughs often take before reaching real patients. The first design for a 3D printed cornea emerged in 2018, and it has only now reached human application. Nevertheless, the rapid progress feels significant, especially when it results in restored sight for patients.
This successful transplant represents a pivotal moment in eye care, suggesting a future where the availability of donor tissue does not dictate who receives sight-saving surgery. As more trial results are released, the potential for this technology to scale and benefit a broader range of patients will become clearer.
