The Applanation Tonometer is still the most widely used instruments to measure interocular pressure. The advan-tage of the "Goldmann" method are considerable. The measurement can be carried out on the patient sitting at the slit lamp in conjunction with other routine microscopic examinations. The accuracy of the measurement is ex-tremely high. The average deviation in any one single examination does not exceed +/- 0.5. mm HG. Furthermore, repeated measuring procedures do not reduce the ocular pressure, as no massing effects occurs. Last but not least, there are no standardization or calibration difficulties.

The Applanation Tonometer 900, an accessory to the Slit Lamp 900, can be especially adapted in an optimum manner to combine with other HAAG-STREIT equipment. Because of its versatility, the Applanation Tonometer can also be mounted onto and combined with other equipment.
