Non-contact Tonometry and pachymetry


Tonometry is a diagnostic test for measuring intraocular pressure by measuring the resistance of the cornea to applied pressure. It is carried out using a tonometer and is measured in mmHg (millimeters of mercury). This method is used in the study of glucoma.

The methods of tonometry are as follows:

Contact – Goldman’s Method and Maklakov Method – A small probe is used. Measurement is based on how much pressure is needed to smooth the cornea.

Non-contact – Non-contact tonometry (pneumotonometry) – This method uses an airflow to corrode and measure the intraocular pressure. The method is fast, painless, lacking touch, so no anesthesia is needed and is very accurate.

Pachymetry is a method of measuring corneal thickness. This study is an indispensable part of the diagnosis of glaucoma. On the other hand, it is necessary to study keratoconus and any surgical procedures on the cornea.

Our clinic has a combined device for contactless tomography and pachymmetry.
