Tonometers Schiotz are used to measure and monitor intraocular
pressure in the eye.
The tonometer Schiotz has a freefloating barrel with
a footplate. Because the footplate radius is greater than that of the
cornea when resting on it, the instrument slightly flattens the cornea.
At the center of the footplate there is a hole through which
a plunger protrudes. The plunger assembly can be loaded with additional
weights so that its total weight varies from 5.5 grams in its unloaded
state to 7.5 or 15 grams.
The movement of the plunger as it indents the cornea amplifies
a mechanical pointer that reads over a scale at the top the instrument.
The scale reading is converted into an approximate value of millimeters
of mercury by use of a graph or conversion chart.
