Haag-Streit AT 900 Applanation Tonometer
The Haag-Streit AT 900 Applanation Tonometer is the gold standard for fast, reproducible IOP measurements.
Thanks to the high-precision of manufacturing at Haag-Streit, the AT 900 applanation tonometer offers reliable
performance over many years without the need for manufacturer maintenance.
Available in 4 models:
- Model R – The Haag-Streit Applanation Tonometer AT 900 model R is fastened to the microscope on a mounting base and swivelled in front of the microscope for the examination. The observation of the applanated surface is conducted monocularly – only through the left eyepiece.
- Model T – The Haag-Streit Applanation Tonometer AT 900 model T is set on the guide plate over the slit lamp axis, for tonometry purposes. The instrument can be moved between two positions on the guide plate for observation through the right or left eyepiece. The sensor arm with the measuring prism projects from the underside into the beam path of the microscope and the illumination. Tonometer will need to be removed from the slit lamp to perform exams.
- Model BC – The Haag-Streit Applanation Tonometer AT 900 for BC/BD/BI slit lamps is fastened to the microscope on a mounting base and swiveled in front of the microscope for the examination. The observation of the applanated surface is conducted monocularly – only through the left eyepiece.
- Model BQ – The Applanation Tonometer AT 900 for Haag-Streit BQ and BP slit lamps has a working position and two resting positions. To set the correct angle of incidence of the illumination, the tonometer is swiveled and the illumination apparatus is positioned to the left of the tonometer bracket. In this position, the patient’s left and right eyes can be easily examined (no 60° position). The applanated surface is observed monocularly through the right eyepiece of the stereomicroscope.
