2. Introduction
The applanation tonometer functions according to the 'Goldmann method': mea‑
surement of the pressure required to maintain a uniform applanation of the surface
of the cornea. The precise measurement of the applanation surface is conducted
with the slit lamp at 10x magnification.
The pressure measurement is conducted on a slit lamp with the patient sitting down
and is a routine test carried out as part of the standard slit lamp microscopy.

trained specialists.
3.1 Model R
A pivot is required for use of the Applanation Tonometer model R o n the BM 900 slit
lamp. It is assembled as follows:
1. Unscrew the mounting screw found at the top, on the microscope's middle cyl‑
inder housing.
2. Leave the spring in the aperture.
3. Position and screw on tightly the pivot for the tonometer.
