長年の実績、世界標準の眼圧測定

Tonosafe Tonometer Prisms

Convenient, safe & accurate

Tonosafe is a Haag-Streit UK single-use tonometer prism and avoids the need for time-consuming and laborious cleaning. It effectively reduces the risk of cross infection, even in the most demanding scenarios. Calibrated to Goldmann standards, Tonosafe delivers accurate results with all Goldmann tonometers.

AT 870

For “Z-Style” slit lamps

The AT 870 is mounted permanently on top of the slit lamp microscope. The feeler arm protrudes from above into the beam path of the microscope and illumination unit.  If the feeler arm is swivelled into the park position, the slit lamp can be used immediately for the examination. The applanated surface is observed monocularly through the left eyepiece of the stereo microscope.
