patient's seat slightly away from the instrument or set it higher.

General notes on instrument operation
•
Choose a slit length that only illuminates that section of the eye
which is to be examined. Otherwise, sections of high reflectance (e.g.
sclera) may be illuminated, thus causing disturbing glare.
•
Turn the filter wheel (
4
, Fig. 23) to choose a filter as required.
•
For retroillumination, set the illumination angle as small as possible
and slightly decentre the illumination by means of control (

•
When using the tonometer, we recommend one looks with the right
eye through the left eyepiece while observing the patient with the
left eye.
•
The use of either convergent or parallel viewing path depends on
your choice.
