What is an applanation tonometry eye exam?

ANSWER

An applanation tonometry eye exam measures the amount of pressure it takes to flatten a portion of your cornea. Pressure readings help your doctor diagnose and keep track of glaucoma. Your doctor will give you drops to numb your eye, then press lightly on it with a tool called a tonometer.
