Comparison of Intraocular Pressure Measurement With the Novel TonoVera Device With Other Commonly Used Devices

This study is comparing eye pressure measurements from a new device called TonoVera against the standard eye pressure measurement tool (Goldmann applanation tonometer), to see whether TonoVera is accurate and could be used in routine eye care. **You may be eligible if...** - You are 18–99 years old - You are in good enough general health to attend your appointment - You are willing to give consent and follow the study procedures **You may NOT be eligible if...** - You are under 18 - You are unable or unwilling to give informed consent - You have a significant eye condition that would interfere with measurement (e.g., uncontrolled eye movements, lid spasm, severe corneal disease) - You have significant thinning of the whites of your eyes (scleral thinning) - You are allergic to proparacaine or fluorescein (the eye drops used for the standard measurement) - You wear contact lenses and cannot remove them before the test Talk to your doctor to see if this trial is right for you.
