Li Y, Shi J, Duan X, Fan F. Tonometry is included as part of a full eye examination. 1 In front of the patient, remove the prism tip from the disinfecting solution, rinse and dry it or wipe it with alcohol. Goldmann applanation tonometry was carried to rule out any rise in intra ocular pressure. Transpalpebral measurement of intraocular pressure using the Diaton tonometer versus standard Goldmann applanation tonometry.
Several techniques may be used. The following is the suggested user- level calibration verification procedure for a Goldmann tonometer. Most new technologies for measuring intraocular pressure ( IOP) fail to measure up to the Goldmann applanation tonometer, according to Yvonne Buys, MD, FRCSC.

The Goldmann applanation tonometer and ocular response analyzer cannot be used interchangeably for measuring intraocular pressure after congenital cataract surgery. Regularly check calibration of your tonometer.During applanation, the measuring drum is revolved to alter the pressure on the eye. Chockalingam DNB FRCS ( Glasgow) PGDHM, N. To compare intraocular pressure ( IOP) measured using a dynamic contour tonometer ( DCT) and a Goldmann applanation tonometer ( GAT) with in vivo intracameral IOP, and establish the relationship between DCT, GAT and central corneal thickness ( CCT) in patients with primary open- angle glaucoma ( POAG). Tonometry is an eye test that can detect changes in eye pressure long before you may be aware of them. It is considered to be the gold standard instrument for measurement of Intraocular pressure ( IOP).
