New Micro Implant Restores Hope and Sight For Glaucoma Sufferers
by M Dee Dubroff
It is estimated that more than 60 million people worldwide and more than 3 million Americans (with only half of those who may know they have it) suffer from glaucoma. despite its severity and endemic proportions, it is a disease that is very misunderstood and underestimated. According to the World Health Organization, glaucoma is the second leading cause of blindness in the world. Up until now, there have only been treatments that slow down the damage caused by this terrible malady. Now there is a solution.

The new micro implant

Glaucoma is caused by intense intraocular pressure that, if left untreated, damages the optic nerve and causes a loss of vision. German researchers at the Fraunhofer Research Institution for Microsystems and Modular Solid State Technologies (EMFT) are developing a miniature pump, which when inserted into the eye, corrects vision over time by regulating  fluids and ocular pressure. The implant consists of a micro-pump system that is applied directly to the eyeball.
According to Christophe Jenke, Project Manager at EMFT, “This way, we can spare the patient from the strain of multiple follow-up procedures,  and can preserve the ability to see over a longer time-frame and, in the best case scenario, completely prevent blindness.”

How does the micro pump work?

The implant may be tiny, but it couldn’t be more technologically sophisticated. It consists of  a micro-pump system that measures just 7X7X1 mm (0.27 X 0.4 in), a sensor-based pump control, an integrated battery and a telemetry module for data transmission. The system is capable of producing up  to 30 micro liters of fluid per second. In Jenke’s own words: “Naturally, the patient should not sense it and his or her eye movements must not be restricted in any way. The system components therefore had to be miniaturized.”……..
