Innovation design

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.

The D-KAT is an accessory for the 'tower illumination' style of Slit lamp.

Keeler are proud to launch the world's first Digital Applanation Tonometer designed specifically for Zeiss type Slit Lamps. British made, the D-KAT Z-type is reliable and easy to use, providing tonometry at it's very best.

The D-KAT Z-type 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.

The LED display enables ease of use in darkened environments, whilst the internal electronics allow for the fast accurate measurement of IOP.
