Javal-Schiotz Keratometer 1950

There are two kinds of keratometers: the Javal-Schiotz and the Helmholtz type. Most ophthalmologists are familiar with the Helmholtz type.
The Javal-Schiotz keratometer uses an adjustable object size. It then requires alignment of a red square and green staircase design.
This specimen is missing the patient support stand that would stick up from the empty hole on the left side.

Keratometers are used to evaluate the corneal shape quantitatively and qualitatively.
