Tonómetro
Applanation Tonometer 900 & 870
Mediciones de la PIO precisas y reproducibles
Las investigaciones del doctor Goldmann sobre el glaucoma condujeron al desarrollo del primer dispositivo para medir la presión intraocular, el tonómetro de aplanación Applanation Tonometer 870, al que siguió el AT 900.
