Eye-on-a-Chip Helps Test Drugs with a Blink

Aug-07-19 An eye-on-a-chip that can blink like a human eye will help researchers develop and test new treatments for dry eye disease.

Developed by a team from Pennsylvania State University, the blinking eye-on-a-chip features a dime-sized porous surface that has been seeded with human eye cells. Artificial tears secreted via a mechanical tear duct are spread across the eye by a ‘slab of gelatin’ that functions as the eyelid—creating a tear film similar to that formed on the human eye.

The blinking eye-on-a-chip should be particularly useful in developing and testing treatments for dry eye disease, and has already aided in the creation of a promising new eye lubrication medication.
