An artificial eye that contains a number of real human corneal cells has been developed to offer an alternative to genetic manipulation . The device , created by researchers from the university of Pennsylvania , also features a clear membrane that surrounds the eye and an ersatz eyelid controlled by a tiny electromechanical device .
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.
