6. INSTRUCTIONS FOR USE
6.1 SETTING THE BINOCULARS
It is vital that the binoculars are optimised for the user’s optical
correction in order to obtain focused binocular images.
1. Remove the Test Bar locating hole cover plate (16) and place the test bar focus in the test
bar location hole at the base of the microscope arm. To access the location hole fi rst remove
the cover. The test bar should be set with the fl at projection face towards the Slit Lamp
Microscope. The illumination and the microscope should be in the zero degrees position.
2. Turn on the Slit Lamp and set the slit to full width (14), set the magnifi cation to x16 (27).
3. Adjust the eyepieces pupillary distance by holding both eyepiece bodies and rotating
them inwards or outwards until they are correct for your PD.
4. Turn both eyepieces (28) to maximum plus (+)
correction.
5. Close one eye, and with the other eye look through
the microscope slowly turning the open eye
eyepiece towards the minus (-) position until the
image of the test bar is in focus. Stop.
6. Repeat the above process for the other eyepiece.
7. Make a note of the positions of the eyepieces so that you can set them quickly if the Slit
Lamp has been used by another clinician.
8. Note – younger examiners are recommended to compensate for their ability to
accommodate by further adjusting the eyepieces by minus one (-1) or minus two (-2)
dioptres.

6.2 PREPARING THE PATIENT AND USING THE SLIT LAMP
Parts of the slit lamp coming in to contact with the patient should be
cleaned in accordance with these instructions prior to the examination.
Tomey recommends the use of disposable hygienic chinrest tissues on the
Chinrest before the patients place their chin on it.
Never use the instrument if visibly damaged and periodically inspect it for
signs of damage or misuse.
1. The patient should be as comfortable as possible and with the patient in the chinrest
adjust the chinrest height (6) so that the patient’s eyes are level with the height marking
(3) on the chinrest support.
2. Focus the eyepieces using the test bar as described earlier, and if you have not already
done so set them to your interpupillary distance by holding both eyepiece bodies and
rotating them inwards or outwards until they are correct for your PD.
3. Switch on the illumination, making sure the rheostat (21) is set to a low level to
minimise the patient’s exposure to light hazard.
4. Rotate the joystick (20) until the light beam is at eye level.
5. Holding the joystick vertical, move the slit Lamp base towards the patient until the slit
beam appears focused on the patient’s cornea.
6. Adjust slit width (14), magnifi cation (27), slit rotation (13) and slit angle etc. as required
to perform the examination.
7. To offset the slit for sclerotic scatter or retro illumination, rotate the illumination prism
assembly (11) to the left or right as desired.
8. When using the blue fi lter (12) the user may wish to insert the yellow barrier fi lter (9).
The yellow barrier fi lter is out when the knob is up, in when it is down.
9. When the examination is complete, set the rheostat to a low level and switch off the Slit
Lamp.
Shut down after every use. In case the dust cover is used: risk of
overheating.
