Fish scale collagen used to 3D print corneas to cure blindness

New Zealand researchers have 3D printed corneas using collagen from fish scales with the aim to use in corneal transplants. Researchers from Massey University (Wellington, New Zealand) have created a 3D printer that can produce corneas for human transplants using collagen from fish scales. This could potentially lead to a cure for blindness, which affects millions. The 3D printer builds the cornea using collagen sourced from the scales of hoki fish that has been shown to be biocompatible in the human body and are a waste product from Kiwi fisheries. "Worldwide, 10 million people need corneal transplants. If you lose...
