Researchers at Biomedical Research Institute of La Paz Hospital (IdiPAZ) in Spain are working to 3D print cornea substitutes, using a patient’s own stem cells and thereby reduce the huge global demand of over 10 million people to donate corneas. The project called ‘Cornal stroma fabrication’ will include use of steam cells from patients to be used for 3D printing the custom corneas and using tissue engineering to regenerate different layers of the cornea for Corneal Transplant.
