The Rexxam Mod-T Plate Mount Applanation Tonometer operates according to the 'Goldmann method', by measuring intraocular pressure from the force required to flatten (applanate) a constant area of the cornea.

​

The T-Type model, which fits most slit lamps and uses applanation prisms,  fixes onto the guide plate on the optical axis for the microscope and illumination unit arm.
