Q. Is a non-contact tonometer painful?

Answer

The tonometry test should not produce any discomfort in the eye. You won't feel the tonometer throughout the test because your doctor will numb the surface of your eyes using eye drops. It's possible that your cornea may feel itchy and scratchy. In most cases waiting 24 hours will resolve the issue. When it is necessary to touch the tonometer to the eye some persons experience feelings of anxiety. In the method known as air-puff tonometry the eye is only made to feel a puff of air.
