An artificial eye that contains a sheet of real human corneal cells has been developed to offer an alternative to animal testing. The new device, called the “retinal prosthetic,” is made from living tissue and can be implanted in patients with macular degeneration.
An artificial eye that contains a sheet of real human corneal cells has been developed to offer an alternative to animal testing. The device, created by researchers from the University of Pennsylvania, also features a clear membrane that replicates the conjunctiva and an ersatz eyelid controlled by a tiny electromechanical motor.
