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

    Designed and manufactured in the UK to the same exacting standards as all Keeler products, the Keeler D-KAT Z 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.
