D KAT – Keeler Applanation Tonometer – ‘Take-Away-T’

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 slit lamp. The T-type is removable and is convenient to use on multiple Slit Lamps.
