Science Daily published an article with the title, 3D printed artificial corneas similar to human ones, we extract the following text, “When a person has a severely damaged cornea, a corneal transplant is required. However, there are 2,000 patients waiting for the cornea donation in the country as of 2018 and they wait for 6 or more years on average for the donation. For this reason, many scientists have put their efforts into developing an artificial cornea. The existing artificial cornea uses recombinant collagen or is made of chemical substances such as a synthetic polymer. Therefore, it does not incorporate well with the eye or is not transparent after the cornea implant.” Read HERE entire article.

Cornea transplant new 3D technique using bioink

Now a new technique is giving hope to patients with this disease. Dong-Woo Cho and Jinah Jang, of Creative IT Convergence Engineering, and Hyeonji Kim, of Postech, in collaboration with Hong Kyun Kim, professor of Ophthalmology at the National School of Medicine in Kyungpook, South Korea, have 3D printed an artificial cornea using biological material manufactured with decellularized corneal stroma and stem cells – bioink (read more about this new technique HERE). The cornea is biocompatible, and the 3D technology mimics its microenvironment, so its transparency is similar to that of the human cornea. The research has been published in the latest edition of the journal Biofabrication (see HERE).

In our opinion, this is, without doubt, a major biotechnological advance, the use of which presents no bioethical problems as the scientists are working with adult somatic cells.
