The gold-standard, highly accurate method of measuring the pressure inside the eye, essential for diagnosing and managing glaucoma.
Applanation tonometry measures intraocular pressure by gently flattening a tiny area of the cornea with a calibrated probe. It is regarded as the most accurate way to measure eye pressure and is the reference standard in glaucoma care.
Numbing drops are used first, so the test is painless. The precise reading helps us start, adjust and monitor glaucoma treatment with confidence.
