長年の実績、世界標準の眼圧測定

AT 900 Type BQ / BP 900

For BQ 900 and BP 900 slit lamps

The device is mounted permanently on the microscope arm. It provides a parking position and can be easily placed into working position. The measurement is obtained through the right eyepiece.

AT 900 Type R

Fits Haag-Streit BI 900 & BM 900 slit lamps, and third party models

Our device fits the Haag-Streit BI 900 and BM 900 slit lamps, as well as many third party models. Mounted on top of the microscope, it can be left on the slit lamp permanently as it provides a parking position and can be easily swiveled into working position. The measurement is obtained through the right eyepiece.

AT 900 Type T

For Haag-Streit BQ 900, BP 900, BM 900 & BI 900 slit lamps

Mounted on a guiding platform placed over the slit lamp axis: the tonometer is placed on the slit lamp only when applanation tonometry is performed. The instrument can be moved between two positions for observation through the right or left eyepiece.

Haag-Streit Tonometers

Fast and reproducible IOP measurement

Goldmann applanation tonometry has been the gold standard in tonometry for many decades. It is based on the Goldmann principle—tried and tested during more than 50 years of usage with millions of patients.
