Comparison of Intraocular Pressure Measurement With the Novel TonoVera Device With Other Commonly Used Devices
State University of New York at Buffalo
Summary
We are testing the accuracy of Reichert's Tono-Vera tonometer by comparing measurements of IOP with this device and measurements with other commonly-used tonometers, including Goldmann Applanation and iCare.
Description
This is a comparative study between the TonoVera, the gold standard Goldmann Applanation Tonometry (GAT) and an established rebound tonometry device, iCare. IOP measurements will be obtained using the following devices: Reichert's prototype Tono-Vera Rebound tonometer (a rebound tonometer in development), iCare's iC100 rebound tonometer (a device commonly used in clinical practice), GAT (a device commonly used in clinical practice). Reichert's iPac Handheld Pachymeter (a device commonly used in clinical practice) will be used to measure the test subject's Central Corneal Thickness (CCT), measu…

Interventions
- DeviceTono-Vera tonometer
The tonometer measures intraocular pressure with a small rebound probe, similar to those used with other tonometers currently on the market, such as the iCare.
- DeviceGoldman Applanation Tonometry
This is the current gold standard for measuring eye pressure.
