D-KAT - Digital Keeler Applanation Tonometer

Discover the new standard ... Keeler D-KAT Digital Applanation Tonometer


New to the Keeler product portfolio is the Digital Applanation Tonometer, (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.

It operates according to the 'Goldmann method', by measuring intraocular pressure from the force required to flatten (applanate) a constant area (3.06mm) of the cornea.

With its LED display and internal electronics it allows for the fast accurate measurement of IOP, (intraocular pressure). Available in both R-Type & T-Type variants. The R type can be fixed to the slitlamp. The T type is removable and is convenient to use on multiple slit lamps.

With less moving parts, the D-KAT is more reliable, accurate and recalibration takes just seconds.
