The first human corneas have been 3D printed by scientists at Newcastle University, UK.
It means the technique could be used in the future to ensure an unlimited supply of corneas.
As the outermost layer of the human eye, the cornea has an important role in focusing vision.
Yet there is a significant shortage of corneas available to transplant, with 10 million people worldwide requiring surgery to prevent corneal blindness as a result of diseases such as trachoma, an infectious eye disorder.
In addition, almost 5 million people suffer total blindness due to corneal scarring caused by burns, lacerations, abrasion or disease.
The proof-of-concept research, published today in Experimental Eye Research, reports how stem cells (human corneal stromal cells) from a healthy donor cornea were mixed together with alginate and collagen to create a solution that could be printed, a ‘bio-ink’.
too many heavy issues are packed up for an entertainment film. Firstly, about Emptiness or Voids that many kids are holding in their heart. Many of the youth feel about themselves as cursed or hurt, having been unreasonably unfairly tormented somehow. Consequently, they come to not bear any hope in the present society or the future.
Secondly, the problem of Unavoidable Diseases and Discriminations Any sorts of discriminations are around us, Disease. Race. Gender, to name a few…
Thirdly, about the Relationship between the Human and the Nature. We get a way to survive by ruining the nature forgetting it’s the nature let us survive. The forth issue is the Negative Human Instincts (Karma). Our fighting instincts easily come up on the surface by Hatred. Rage. The fifth. Our Ambivalent Position, the Heart in Awe vs. Pragmatism. While we feel awed to the unearthly events we yet tend to rationalise everything.
