3D printed cornea restores sight in world first
NEWYou can now listen to Fox News articles!
Surgeons at Rambam Eye Institute have made medical history.
They restored sight to a legally blind patient using a fully 3D printed corneal implant grown entirely from cultured human corneal cells. This marked the first time a corneal implant that did not rely on donor tissue had ever been transplanted into a human eye.

A breakthrough that turns one donor cornea into hundreds
The cornea came from a healthy deceased donor and was then multiplied in the lab. Researchers used the cultured cells to print about 300 transparent implants with Precise Bio’s regenerative platform.
Their system builds a layered structure that looks and behaves like a natural cornea. It is designed to provide clarity, strength and long-term function.
HOW A TINY RETINAL IMPLANT IS HELPING PEOPLE REGAIN THEIR SIGHT
Since donor shortages prevent millions from receiving sight-saving care each year, this approach could transform access. Many patients in developed countries wait only a few days for a transplant, while others wait years due to low tissue availability. A single donor cornea that can create hundreds of implants changes that equation.

The surgery that proved it works
Professor Michael Mimouni, director of the Cornea Unit in the Department of Ophthalmology at Rambam Eye Institute, led the surgical team. He described the moment as unforgettable because the lab-grown implant restored sight to a real patient for the first time.
He says, “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. We can hopefully reduce waiting times for all kinds of patients waiting for all kinds of transplants.”
The procedure is part of an ongoing Phase 1 clinical trial that assesses safety and tolerability in people with corneal endothelial disease. This achievement reflects years of work across research labs, operating rooms and industry. It also shows how coordinated teams can push new treatments from concept to clinical reality.
How the science fits into a bigger future
The breakthrough will have a permanent home in Rambam’s upcoming Helmsley Health Discovery Tower. The new Eye Institute will consolidate care, training and research under one roof. It aims to speed the move from emerging science to real-world treatment for patients across Northern Israel and beyond.
Precise Bio says its 3D printing system could eventually support other tissues like cardiac muscle, liver and kidney cells. That future will require long trials and extensive validation, but the path now looks more achievable.

What this means for you
If corneal disease affects someone in your family, this work brings new hope. Donor tissue may continue to play a role in many regions, but lab-grown implants offer a way to expand access where shortages hold patients back. The success of this first transplant also suggests a future where regenerative medicine supports many types of tissue repair.
This milestone also shows how long scientific breakthroughs take to reach real patients. The first 3D printed cornea design appeared in 2018 and only now reached human use. Even so, the progress feels fast when the result is restored sight.

Kurt’s key takeaways
This successful transplant marks a turning point for eye care. It suggests a world where the limits of donor supply do not decide who receives sight-saving surgery. As more trial results arrive, we will see how far this technology can scale and which patients stand to benefit first.

Relativity Space, the rocket company led by former Google executive Eric Schmidt, was picked to launch NASA’s Aeolus payload to Mars in 2028, as reported earlier by TechCrunch. Under a new public-private partnership, Relativity Space will provide the “spacecraft, rocket, and cruise operations” to fly Aeolus to Mars, where the payload will “provide the first integrated, daily, global view of Martian winds, temperatures, dust, and clouds.”
The Aeolus payload will have four instruments on board for studying the Martian atmosphere, which NASA says will “directly inform entry, descent, and landing systems and support safer, more predictable mission planning for astronauts.”
Schmidt, who served as CEO of Google from 2001 to 2011, became Relativity Space’s CEO in 2025, a couple of years after it launched the “world’s first 3D-printed rocket,” Terran 1, which failed shortly after launch. Relativity Space’s larger Terran R rocket isn’t scheduled to have its first launch until later this year.

– Jeff Bezos predicts AI will create a labor shortage, not replace human workers across the economy
– OpenAI faces multistate investigation into data handling and chatbot behavior
– AI-designed ‘universal vaccine’ passes first human clinical trial, could prevent future pandemics
WORK IN PROGRESS: Amazon founder Jeff Bezos said the rise of artificial intelligence (AI) won’t lead to the replacement of humans in the workforce and will instead create labor shortages.

UNDER SCRUTINY: OpenAI faces a multistate investigation led by New York Attorney General Letitia James, scrutinizing its data handling, minor safety and chatbot behavior. This comes as the company reportedly slashes product prices and prepares for a potential IPO, amid accusations from Florida’s AG regarding unsafe product releases.

Five months after returning to OpenAI, Barret Zoph — the company’s head of enterprise AI sales — has departed, The Verge has learned.
Zoph returned to OpenAI in mid-January after a stint as co-founder and CTO of Thinking Machines Lab, the competing AI company founded by former OpenAI CTO Mira Murati. Shortly after Zoph returned to OpenAI, the company said he would lead its push into enterprise — a significant role at OpenAI, since in recent months it had vowed to stop chasing so-called “side quests” and focus on key revenue drivers like enterprise and coding ahead of its planned IPO.
OpenAI confirmed to The Verge that Zoph will be departing. He posted a goodbye message in the company’s Slack channels. Zoph did not immediately respond to a request for comment.
Zoph originally left OpenAI in the fall of 2024 for Murati’s Thinking Machines Lab, but departed the role abruptly in January 2026 after reports of alleged misconduct involving an undisclosed relationship with a colleague. Murati posted on X in January that Thinking Machines Lab had “parted ways” with Zoph and that he would be replaced as CTO.
Thinking Machines Lab has its own tensions with OpenAI. Murati briefly took over as CEO from OpenAI CEO Sam Altman during his November 2023 ouster, and during the recent OpenAI trial, Murati testified that she couldn’t trust everything Altman said. In September 2024, when Murati left OpenAI to start Thinking Machines Lab, a group of OpenAI employees followed shortly after. But three of them — including Zoph — all returned to OpenAI together this past January. Fidji Simo, OpenAI’s CEO of Applications, wrote on X at the time that she was “excited to welcome Barret Zoph, Luke Metz, and Sam Schoenholz back” and that the decision had “been in the works for several weeks.”
