Learn about glaucoma, a leading cause of blindness, its various causes, types, and the lack of symptoms. Explore the potential of a smart lens developed at UC Davis to continuously monitor glaucoma by utilizing a conductive organic polymer. Discover how this innovative technology generates error signals based on lens distortion and voltage changes. Find out the benefits of this monitoring system, including reduced doctor visits and augmented reality.

Glaucoma Monitoring • Stephen Sladen • 10/4/2011 • BME 281 Section 2 • Dr. Sun
Glaucoma • A leading cause of blindness • Affects our optic nerve (II) • Different causes and types • No cure or symptoms (“Silent Thief”) • Treatment and monitoring
Smart Lens • Tingrui Pan at UC Davis • Allows for continuous monitoring • PDMS, an organic polymer • Making the polymer conductive
Putting the Pieces Together • Added agent causes UV light sensitivity • Silver powder forms circuit, antimicrobial • Cured and restored properties
Error Signals • Pressure on retina causes lens distortion • Voltage changes generate signal
What’s in store… • Human trials • Corrective vision
The original idea • Babak Parviz @ UW • Generates computer images • Seen outside field of vision • Problems organic vs. inorganic • Rabbit testing
Conclusion • Non-frequent doctor visits • Augmented reality • Peace at mind
