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).

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.

Setting the Aperture
Aperture Lever
Selection (H)
By rotating the knob (H)
different apertures may
be selected.
Large
The large, round, homogeneous patch is suitable for routine
examinations through fully dilated pupils. In this position the
mirror remains in the forward position and the optics are diverged.
Intermediate
The intermediate patch is designed to reduce reflections when
entering a partially or poorly dilated pupil (3mm). It is also ideal
for closer inspection of particular fundal areas. The mirror and
optics stay in the mid position.
Small
This light patch is ideal for small, undilated pupils. The mirror
moves back and the optics automatically converge.
The Keeler Vantage Plus
has 3 light apertures which
offer maximum stereopsis.
When you select the
aperture the illumination
and viewing mirrors
automatically adjust for
maximum stereopsis. Illumination Angle

Filter Lever Selection (I)
By rotating the lever (I),
different filters may
be selected.
Blue Circle
Cobalt blue filter for fluorescein angioscopy.
White Circle
Clear light – Select the clear with no filter when inspecting a
specific pathology and a brighter, whiter light is desired.
Green Circle
Red Free filter – this filter reduces the red light, so blood will
appear black, silhouetted against a dark background.
Diffuser
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
the alignment between the headset, the condensing lens and the
pupil, in order to achieve a full lens image, is not as critical as
with the conventional beam.
