AT 900®D Mod. BQ
Apart from the working position, the Applanation Tonometer AT900®D mod. BQ has also two resting positions. For perfect tonometric examination the tonometer is swung in front of the microscope and the illumination unit moved from the left to touch the bracket of the tonometer. In this position, the left and right eye of the patient can be examined without difficulties (no 60° position). The applanation surface is to be examined in a monocular manner through the right ocular of the stereo-microscope.
