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 AT 900®. It is a powerful accessory to the Haag-Streit 900 series 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
  • Can be used with virtually any slit lamp
