1. The Triggerfish Lens and Glaucoma Monitoring By Samuel Karnes

2. Glaucoma Intraocular pressure on the optic nerve o Blindness Four types o Chronic (open angle) o Angle Closure (acute) o Congenital o Secondary

3. Triggerfish Lens Sensimed AG Strain gauges o around the outer edge Micro-processor Antenna o Radiofrequency waves Bluetooth

4. Current Glaucoma Tests Tonometry Procedures Eye is numbed with numbing drops o Slit-lamp is moved forward until tonometer touches the eye o Handheld device touches the eye and takes pressure reading o Pressure is read from change in light reflections when air hits the eye (Air Puff) Each procedure only reads IOP for a few seconds

5. Advantages 24 hour IOP monitoring Silicon hydrogel (used for regular contact lens) o Easy to wear Non-Invasive

6. Disadvantages Not available in U.S. currently Each lens only provides a single use Common adverse effects o Eye irritation o Blurred vision

7. Testing Results Effective results for 36 of 40 patients 82% blurred vision 80% inflammation and reddening of the eye o Symptoms usually went away within 24 hours

8. Conclusion Lens collects more data than current tests o Seconds of monitoring vs. hours Long term o More accurate diagnoses o Better information for finding a possible cure
