To use the device, the individual has to rub a probe over the eyelid, and the device detects the stiffness and calculates the intraocular pressure.

The device, which can also measure drainage of intraocular fluid, uses a system of micro-force sensors, specially designed microchips, and has math-based procedures programmed into its memory.

The project has been funded by The National Science Foundation and the researchers are seeking investors for the final development and commercialization of the product.
