Whether you’re seeking the gold standard in tonometry—the Goldmann applanation tonometer—or a convenient hand-held option in the Perkins applanation tonometer, you can count on reliable performance.

The gold standard in tonometry

Enjoy the most accurate IP measurement with the Goldmann Applanation Tonometer 870®. It is a powerful accessory to use on your Zeiss style slit lamps, allowing IOP measurements to be taken with the patient at the slit lamp as part of a routine exam.

Achieve the best IOP measurements
The Applanation Tonometer remains the most widely used instrument to measure interocular pressure. Its benefits include:

  • A high accuracy of measurement: when using the correct procedure, the average deviation in a single exam does not exceed ± 0.5 mm Hg.
  • Best reproducibility
  • Reliable and durable
