Digital 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 Z-type (Zeiss) or the R-type post or the T-type aluminium guide plate for slit lamp use.

In addition to the standard applanation tonometer, Keeler also carries Digital Applanation Tonometers (D-KAT). Designed and manufactured in the UK to the same exacting standards as all Keeler products, the Keeler D-KAT delivers reliability and ease of use. With its LED display and internal electronics it allows for the fast accurate measurement of IOP (intraocular pressure). Available in R-type, T-type, and Z-type (Zeiss style) models. With less moving parts, the D-KAT is more reliable, accurate and recalibration takes just seconds.

R-Type Applanation Tonometers
R-type style applanation tonometer is available in traditional or digital formats. It is designed to be used with the H series 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.

T-Type Applanation Tonometers
T-type style applanation tonometer is available in traditional or digital formats. It is designed to be used with the H series slit lamp (tower illumination). The T-type tonometer is a takeaway model allowing for the unit to removed when not in use.

Z-Type Applanation Tonometers
Z-type style applanation tonometer is only available in a digital format. It is designed to be used with the Z series slit lamp (lower illumination). The Z-type tonometer is fixed allowing for it to easily swing into and out of position as needed without being removed.
