For the first time in history, scientists have 3D printed human corneas, Science Daily reports. This incredible feat of engineering was achieved by researchers at Newcastle University in the U.K., who hope that their work can help relieve the serious shortage of corneas available for transplant.
According to Newcastle University, some 15 million people all over the world are in need of a cornea transplant, either to prevent disease-induced corneal blindness or because they have lost their vision due to scarring of the cornea as a result of burns, lacerations, or disease.
With the help of 3D bioprinting, researchers could “ensure an unlimited supply of corneas,” states the university.
In a study published today in the journal Experimental Eye Research, the Newcastle team points out that the artificial corneas were made using a normal 3D bio-printer. The innovative thing about them, however, is the material used for 3D printing, a special “bio-ink” created from stem cells.
