11.2 preparing the patient and uSing the Slit lamp
1 The patient should be as comfortable as possible and with the patient
in the chinrest adjust the chinrest height (7) so that the patient’s eyes
are level with the height marking (4) 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 (25) is set to a low
level to minimise the patient’s exposure to light hazard.
4 Rotate the joystick (24) 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 (18), magnification (31), slit rotation (13) & slit angle
etc. as required to perform the examination.
7 Loosening slit offset centring knob (16) to allow the slit image to be
moved off centre for scleral illumination. Tightening the knob will re-
centre the slit image in the centre of the visual field of the microscope.
8 The slit image is made vertical, or given a preset angle by means of the
illumination latch (17) (notches at 5°, 10° and 15° & 20°).
9 When using the blue filter (12) the user may wish to insert the yellow
barrier filter (29). The yellow barrier filter is out when the knob is up, in
when it is down.
10 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.
Parts of the slit lamp coming in to contact with the patient
should be cleaned in accordance with these instructions prior
to the examination. Keeler 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.
