Professor Goldmann's research into glaucoma led to the development of the first device for measuring intraocular pressure, the Applanation Tonometer 870 followed by the AT 900. 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. AT 900 model BQ 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 model 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 model 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. 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.
