This test measures the amount of force needed to temporarily flatten part of your cornea. The test involves using a slit lamp equipped with forehead and chin supports and a tiny, flat-tipped cone that gently comes into contact with your cornea. This pressure measurement helps your doctor determine whether you may be at risk of developing glaucoma.
