6.1.1 ri-scope® L otoscope
1 2 3 4
1) Ear speculum
2) Bayonet mount
3) Swivel lens, 3x magnification
4) Operation lens
5) Push button for ear speculum ejection (L3 only)
Purpose/indications
The Riester otoscope described in these operating instructions is produced for illumination
and examination of the auditory canal in combination with Riester ear specula.
Attaching and removing ear specula
The otoscope head can take either disposable Riester ear specula (in black) or reusable
Riester ear specula (in black). The size of the ear speculum is marked at the back of the
speculum.
Otoscope L1 and L2
Turn the speculum clockwise until you feel resistance. To remove the speculum, turn it
counter-clockwise.
Otoscope L3, EliteVue Fibre Optic Macro Otoscope
Place the selected speculum on the chromed metal fitting of the otoscope until it clicks
into place. To remove the speculum, press the blue eject button. The speculum will detach
automatically.
Swivel lens for magnification
The swivel lens is fixed to the device and can be swivelled 360°.
Inserting external instruments into the ear.
If you wish to insert external instruments into the ear (e.g. forceps), you have to turn the
swivel lens (approx. 3x magnification) located on the otoscope head by 180°. You can now
insert the operating lens.
Pneumatic otoscopy
Pneumatic otoscopy (an examination of the eardrum), requires an insufflator bulb which is
not included but may be ordered separately. The hose of the bulb is put on the connection.
You can now carefully introduce the necessary amount of air into the ear canal.

6.1.2 ri-scope® L ophthalmoscope
1 2 3 4 5
1) Dioptre display
2) Dioptre wheel
3) Aperture symbols
4) Aperture wheel
5) Filter wheel
6) Bayonet head
Purpose/indications
The Riester ophthalmoscope described in these instructions for use is produced for exami-
nation of the eye and fundus.
Because prolonged intense exposure to light can damage the retina, the use of the eye exam
device should not be unnecessarily prolonged, and the brightness setting should not be set
higher than needed for a clear representation of the target structures.
The irradiation dose of the photochemical exposure to the retina is the product of irradiance
and duration of irradiation. If the irradiance is reduced by half, the irradiation time may be
twice as long to reach the maximum limit.
Although no acute optical radiation hazards have been identified for direct or indirect opht-
16

halmoscopes, it is recommended that the intensity of light directed into the patient's eye be
reduced to the minimum required for examination/diagnosis. Infants / children, aphasics
and people with eye diseases are at higher risk. The risk may be increased if the patient has
already been examined with this or another ophthalmological instrument during the last 24
hours. This is especially true when the eye has been exposed to retinal photography.
The light of this instrument may be harmful. The risk of eye damage increases with the
duration of irradiation. An irradiation period with this instrument at maximum intensity of
longer than >5 min. exceeds the guideline value for hazards.
This instrument does not pose a photobiological hazard according to DIN EN 62471 but still
features a safety shutdown after 2 - 3 minutes.
Lens wheel with correction lenses
The correction lenses can be adjusted using the lens wheel. The following correction lenses
are available:
Ophthalmoscope L1 and L2
Plus: 1-10, 12, 15, 20, 40.
Minus: 1-10, 15, 20, 25, 30, 35.
Ophthalmoscope L3
Plus: 1-45 in single steps
Minus: 1-44 in single steps
The values can be read off in the illuminated field of view. Plus values are indicated by green
numbers, minus values by red numbers.
Apertures
The following apertures can be selected using the aperture setting wheel:
Ophthalmoscope L1
Semi-circle, small/medium/large circular aperture, fixation star, slit.
Ophthalmoscope L2
Semi-circle, small/medium/large circular aperture, fixation star and slit.
Ophthalmoscope L3
Semi-circle, small/medium/large circular aperture, fixation star, slit and grid.
Aperture function
Semi-circle: for examination of cloudy lenses
Small circle: for reflex reduction in small pupils
Medium circle: for reflex reduction in small pupils
Large circle: for normal fundus examinations
Diamond: for topographical determination of retinal changes
Slit: to determine differences in level
Fixation star: for determination of central or eccentric fixation
Filters
The following filters can be applied to each aperture using the filter wheel:
Ophthalmoscope L1 red-free filter
Ophthalmoscope L2 red-free filter, blue filter and polarization filter.
Ophthalmoscope L3 red-free filter, blue filter and polarization filter.
Filter function
Red-free filter: contrast-enhancing to assess fine vascular changes e.g. retinal
haemorrhages
Polarizing filter: for precise assessment of tissue colours and to reduce corneal
reflections
Blue filter: for better detection of vascular anomalies or haemorrhages,
for fluorescence ophthalmology
With L2 + L3 every filter can be applied to every aperture.
Focusing device (L3 only)
By turning the focusing wheel, you can quickly fine-tune the examination area to be viewed
at various distances.
Magnifying glass
A magnifying glass with 5x magnification is supplied with the ophthalmoscope set. This can
be held between the instrument head and the examination area as required. The examina-
tion area is enlarged accordingly.
