4. Safety
Safety considerations
It is well established that exposure of the eye to intense light
sources for extended periods of time poses a risk of retinal photic
injury. Many ophthalmic instruments illuminate the eye with
intense light. The decision about the intensity of the light level to
use in any procedure must be made on a case to case basis. In
each case, the clinician must take a risk benefit judgement about
the intensity of light to be used. Use of insufficient intensity may
result in inadequate visualization and in adverse effects more
serious than retinal photic damage. Further, despite all efforts
taken to minimise the risk of retinal damage, damage may still
occur. Retinal photic injury is a possible complication of the need
to use bright light clearly visualize ocular structure during delicate
ophthalmic surgical procedure.
While no visible retinal lesions have been identified for
ophthalmic instruments, it is recommended that illumination
levels be set to the minimum level necessary to perform the
diagnostic function. Young children and persons with diseased
eyes may be at a higher risk. The risk may also be increased if the
person being examined has had any exposure with the same
instrument or any other ophthalmic instrument using an intense
visible light source during the previous 24 hours. This will apply
particularly if the eye has been exposed to retinal photography.
The light emitted from this instrument is potentially hazardous.
The longer the duration of exposure, the greater the risk of
ocular damage. Exposure to light from this instrument when
operated at maximum intensity will exceed the safety guideline
after 27 minutes.

5. Setting up and using the Vantage Plus
Headband Adjustment
Comfortable Fit
Adjust the size (A) fig.1 and the height (B) fig.2, so
that the instrument is supported comfortably
around and on top of the head.
Ophthalmoscope Angle Alignment
For vertical alignment of the eyepieces and
binocular block (O), adjust the height of the Metal
Outer Brow Bar (C) if necessary by using the
browband tension knobs (D) located on the sides
of the headset (fig 3).
Position the Binocular Block (O) as close to the
eyes or spectacles as possible for maximum field of
view. Slightly loosen the ophthalmoscope angle
knob (E) to allow for adjustment and tighten when
in position as in (fig 4).
10

5. Setting up and using the Vantage Plus
Interpupillary Distance Setting Control (S)
Because the eyes are dissociated, particular care must be taken to
ensure the optics (eyepieces) are set properly in front of each eye.
Always set the Aperture Selection (H) to the large light patch for
this exercise.
Place an object, perhaps the thumb, approximately 40cm from the
face and centre it horizontally in the light patch. Then, close one
eye. Using the thumb and forefinger of the opposite hand, slide
the P.D.Control (S) of the open eye (located directly under each
eyepiece) so that your object moves into the centre of the field,
keeping the object in the centre of the light patch. Repeat for the
other eye.
Obtaining a fused image
Ensure that a singular, fused image is obtained as follows:
Mirror Angle Control (J)
The light is positioned vertically into the upper two thirds of the
field of view by rotating the spindle (J) located on either side of
the binocular block.
Head Dimmer Switch (T)
Turn the illumination on by rotating the headband dimmer (T)
in an anti clockwise direction.

5. Setting up and using the Vantage Plus
This unique extra wide beam of diffused light permits a more
relaxed technique during more challenging fundus
examinations.
Beginners may also find this aperture particularly helpful
since, in order to achieve a full lens image, the alignment
between the headset, the condensing lens and the pupil is

The Keeler Vantage Plus LED uses RF energy only for its internal function.
Therefore, its RF emissions are very low and are not likely to cause any
interference in nearby electronic equipment.
The Keeler Vantage Plus LED is suitable for use in all establishments,
including domestic establishments and those directly connected to the
public low-voltage power supply network that supplies buildings used for
domestic purposes.

recommended separation distances calculated from the equation applicable
to the frequency of the transmitter.
Recommended separation distance
d = 1.2 √ p
d = 1.2 √ p 80MHz to 800 MHz
d = 2.3 √ p 800MHz to 2.5GHz
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.²
Interference may occur in the vicinity of
equipment marked with the following symbol:
Note 1 At 80MHz and 800MHz, the higher frequency range applies.
Note 2 These guide lines 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
and TV broadcast 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 Keeler Vantage Plus LED is used exceeds the applicable RF compliance level
above, the instrument should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorientating or relocating the Keeler Vantage Plus LED.
² Over the frequency range 150kHz to 80 MHz, field strengths should be less than 3 V/m.

11. Annex I – EMC statement and guidelines
Recommended separation distances between portable and mobile RF communications equipment and the Keeler Vantage Plus LED
The Keeler Vantage Plus LED is intended for the use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the
user of the Keeler Vantage Plus LED can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the Keeler Vantage Plus LED as recommended below, according to the maximum output power of the
communications equipment.
