6.2 PREPARING THE PATIENT AND USING THE SLIT LAMP

Parts of the slit lamp coming into 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 minimize 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.
    TOMEY TSL-4000Z Z Series Slit Lamp User Manual  & troubleshooting 60
  6. Adjust slit width (14), magnification (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 filter (12) the user may wish to insert the yellow barrier filter (9). The yellow barrier filter is out when the knob is up, in when it is down.

Where p is the maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer and d is the recommended separation distance in metres (m).
Field strengths from fixed RF transmitters, as determined by an electromagnetic site survey¹, should be less than the compliance level in each frequency range.²TOMEY TSL-4000Z Z Series Slit Lamp User Manual  & troubleshooting 66Interference may occur in the vicinity of equipment marked with this symbol.

Note: At 80MHz and 800MHz, the higher frequency range applies. These guidelines may not apply in all situations.
Electromagnetic propagation is affected by absorption and reflection from structures, objects, and people.

  1. Field strengths from fixed transmitters, such as base stations (cellular/cordless) telephones and land mobile radios, amateur radio, AM, and FM radio broadcast,s and TV broadcasts cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey
    should be considered. If the measured field strength in the location in which the Tomey Slit Lamp is used exceeds the applicable RF compliance level above, the Tomey Slit Lamp should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orientating or relocating the
    Tomey Slit Lamp.
  2. Over the frequency range 150kHz to 80 MHz, field strengths should be less than 10 V/m.

9.3 RECOMMENDED SAFE DISTANCES
Recommended separation distances between portable and mobile RF communications equipment and the Tomey Slit Lamp
The Tomey Slit Lamp is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of the Tomey Slit Lamp can help prevent electromagnetic interference by maintaining a minimum distance between mobile RF communications equipment (transmitters) and the Tomey Slit Lamp as recommended below, according to the maximum output power of the communications equipment.

Rated maximum output power of the transmitter (W) Separation distance according to the frequency of the transmitter (m)
150 kHz to 80MHz d = 1.2√ p 80MHz to 800MHz d = 1.2√ p 800MHz to 2.7GHz

d = 2.3√ p

0.1 0.38 0.38 0.73
1 1.2 1.2 2.3
10 3.8 3.8 7.3
100 12 12 23

For transmitters rated at a maximum output power not listed above, the recommended separation distance in meters (m) can be determined using the equation applicable to the frequency of the transmitter, where p is the maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer.
Note: At 80MHz and 800MHz, the separation distance for the higher frequency applies. These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects, and people.
