In a revolutionary advancement, scientists at Newcastle University have successfully 3D-printed a living human cornea using stem cells and a bio-ink made from alginate (derived from seaweed) and collagen. This printable mixture maintains both the softness needed for printing and the structural integrity required to form a usable cornea. Remarkably, the printing process takes under 10 minutes. What makes this breakthrough even more powerful is its customization. By scanning a patient’s eye, doctors can print a perfectly sized and shaped cornea. With over 10 million people globally affected by corneal blindness and a dire shortage of donor tissue, this innovation could one day allow hospitals to print corneas on demand—offering sight-saving treatment to millions. #3DPrinting #MedicalInnovation #StemCellResearch #BlindnessCure #FutureOfMedicine
