Standard contact tonometers

The Goldmann principle is considered to be the most prevalent method of tonometry, as it is the most widely accepted method of determining the approximate intraocular pressure. The Keeler-manufactured applanation tonometers are designed and built to our exacting standards to give you the accuracy and quality you expect from a Keeler device. All KAT tonometers are supplied with one reusable doubling prism, the calibration check bar, and either the R-Type post or the T-Type aluminium guide plate for slit lamp use.

KAT (R-Type) applanation tonometer
Available in analogue or digital formats. It is designed to be used with the H-style slit lamp (tower illumination). The R-Type tonometer is fixed allowing for it to easily swing into and out of position as needed without being removed.

KAT (-Type) applanation tonometer
Available in analogue or digital formats. It is designed to be used with the H-style slit lamp (tower illumination). The T-Type tonometer is a takeaway model allowing for the unit to be removed when not in use or shared in a multi slit lamp practice.
