Run away! 3d printing human cornea is coming out! The result of the efforts of scientists at Newcastle University in the UK day and night! This will change the era of corneal repair, no longer rely on the donor’s cornea, will bring good news to millions of patients with eye diseases!

The cornea is a transparent layer on the front of the eye that covers the iris, pupil, and anterior chamber. 3D printing of the human cornea may end the waiting time for patients who need to transplant the cornea.

3D printing is a manufacturing process that creates a physical object from a digital design. The technology is evolving rapidly, and 3D printers are used to make everything from prosthetics (hands) to bottle openers.

Now, according to a paper published in the Journal of Experimental Eye Research on May 30, 2018, scientists are using 3D printers to make human corneas. A progress may greatly ease the shortage of donor corneas.

Prior to this, people who needed corneal transplantation to improve their vision were included in more and more waiting lists, waiting to receive organs. Donor’s cornea. Researchers estimate that every 70 patients in the world who need to donate corneas “grab” the cornea of ​​an organ donor. However, this promising 3D printing technology can help people see things better without waiting for a long time.

The cornea consists of clear layers of cells that together protect the inner workings of the eye, focusing the light to provide a clear vision. If the cornea is damaged, cannot heal or cannot be repaired, it can be replaced with a healthy cornea donated by humans. This is where 3d printing technology comes into play.

Researchers at Newcastle University in the UK use a corneal stem cell, collagen and alginate, an organic polymer extracted from the stem of seaweed. Bio-ink” prints a concentric circle of corneal shape. Alginate helps the cornea retain its shape, while collagen keeps stem cells alive until they grow into mature corneas.

The 3d printed cornea may be used for surgery, or keratoplasty, to replace some or all of the damaged cornea with corneal tissue. Researchers are currently working to ensure that the cornea works properly, ensuring that the body does not attack and repel them after implantation. This process may take several years, but one day it will change the way many people think about the world.
