notes: label: Description
content: An optical tonometer determines intraocular pressure by measuring the resistance of a cornea to indentation. The basic form was invented by a German professor in 1862. Hjalmar August Schiőtz, a Norwegian ophthalmologist, presented his design to the Norwegian Medical Society in 1905. The inscriptions on the case of this example read “SCHIOTZ TONOMETER” and “SKLAR / PRODUCTS.” Those inside the case read “IMPROVED MODEL / SCHIOTZ TONOMETER” and “A SKLAR / PRODUCT.” That on the instrument reads “SKLAR.”
