3D printed eyes: Scientists develop artificial cornea in medical breakthrough | Science | news



The first human corneas originating from a cost-effective 3D printer were developed by a team of researchers from Newcastle University in the UK.

The unbelievably bizarre achievement was unveiled in the journal Experimental Eye Research

Che Connon, professor of tissue engineering at Newcastle University, praised the medical breakthrough in the use of cheaper materials.

Professor Connon said, "Many teams around the world are pursuing the ideal biotin process.

" Our unique gel – a combination of alginate and collagen – keeps the stem cells alive and produces a material that is stiff is enough to retain its shape but soft enough to be pushed out of the nozzle of a 3D product

"This builds on our previous work of keeping cells within a similar hydrogel alive for weeks at room temperature

"Now we have a ready-to-use bio-ink containing stem cells that allows users to print tissue without having to worry about growing cells separately.

The cornea is a crucial element in the outer layers of the eye, which serves to focus the vision.An estimated five million people experience blindness due to corneal injury and disease.

Worldwide, 1

0 million people require surgery to treat corneal blindness However, there is widespread absence of corneas ready for transplantation.

The Royal National Institute of the Blind (RNIBP) estimates more than two million people, or one in 30, live in the UK with vision loss.

Corneal dystrophies are one of the most common corneal diseases caused by inflammation, infection or other eye diseases.

The RNIBP said: "The surface of the cornea is very sensitive. It contains many nerve endings and can detect even the smallest piece of dirt or lint.

"The cornea acts as a barrier between your eye and the outside world, helping to protect it from injury and infection.

" Your cornea is important for vision. It bends and focuses the light into the eye.

"The light is then further focused through the eye lens on the retina, on the back of the eye."

Scientists now have a solution in the form of so-called bio-ink – a liquid mixture of stem cells, collagen and alginic acid

Using a simple 3D printer, Newcastle scientists were able to print an artificial human cornea in less than 10 minutes.

The Corneal Pressure Method May (19659005) By scanning a patient's eye, doctors were able to continue to print tailor-made corneas to match the patient's eye shape and size.

Professor Connon said: "Our 3 – D printed cornea. We have to go through more tests and there will be more Years to be able to use them for transplantation. "

" However, we have shown that it is possible to print corneas with the help of coordinates – a patient eye and that approach has the potential to be global to fight.

The unbelievable news follows that scientists in the US have successfully combined stem cell clusters with chick embryos to find out how fetuses develop in the womb.
