The Keeler Applanation Tonometer (KAT) is a perfect example of Keeler skills; they have applied 21st Century design techniques to an old established principle to deliver a premium quality instrument.

The Goldmann applanation principle is widely acclaimed as the most common and direct method of assessing IOP. The KAT is made with precision machined components that are subject to stringent quality controls pre, during and after assembly in their Windsor factory to add reliability and repeatability to an established technique.
