Usage overview

All Keeler Applanation Tonometers (KATs) use the Goldmann method of measuring intraocular pressure (IOP), which involves calculating the force required to flatten a constant area of the cornea (3.06mm in diameter). The force is applied to the cornea by correct use of the slit lamp, applanation tonometer and tonometer prism. This method is trusted globally, as the ‘gold-standard’ for accuracy, to aid in the diagnosis of glaucoma.

We offer three variants of GAT. Designed to be used with tower-illumination H-style slit lamps, the R-Type is mounted on the optical body post for a secure fix, whilst the T-Type can easily be removed for wider use within a multiple slit lamp practice. Our newest KAT, the Z-Type is designed for use with lower-illumination Z-style slit lamps.

As an T-Type, this unit can be mounted with a guide plate, making it fully removable for wider use within a multiple slit lamp practice.
