    Porcine dermal collagen was chemically and photochemically bioengineered into an implantable tissue mimicking the human corneal extracellular matrix. The implant presents a simpler and safer method than donor cornea transplantation while delivering equivalent outcomes, and has restored vision to people with advanced keratoconus in resource-limited regions, where the burden of blindness is highest.
