4.1 Installation safety
NOTE
Damage during assembly, cleaning and transport
The device can be damaged during assembly, cleaning and
transport if the measuring arm with the measuring prism holder is
not at a defined position.
u
When assembling, cleaning or transporting the AT 030 appla-
nation tonometer, the measuring element must be set to 2.0.
NOTE! The device may be used only for seated patients, i.e.
in horizontal measuring direction.
4.2 General information
The device can be mounted on ZEISS slit lamps by using a special
tonometer holder. Special tonometer holders have been specifically
developed for the use of the AT 030 with ZEISS slit lamps and can
be purchased separately.
The tonometer holder permits observation of the measuring prism
through the left or right eyepiece of the slit lamp microscope. For
this purpose, AT 030 is plugged into the alignment holes on the
base plate.
The easily replaceable measuring prism of AT 030 contains an
optical system that divides the image of the applanation surface in
two halves.
The measuring force applied to the eye via the measuring prism can
be adjusted between 0 mN and 78 mN by turning the rotary knob
of the graduated drum. The scale value is 0.98 mN.
For movements towards the patient, the device has a spring-loaded
stop to avoid injuries arising from inadvertently coming too close to
the eye. Restricted visual acuity of the operator can be compen-
sated for by using adjustable eyepieces on the slit lamp.
