• Use of this device adjacent to or stacked with other equipment
should be avoided because it could result in improper operation. If
such use is necessary, this device and the other equipment should
be observed to verify that they are operating normally.
• Grounding reliability can only be achieved when unit is connected to
a hospital grade receptacle. (Not valid for EU countries).
• The device should be set up in such a way that the plug is always
easily accessible and the device can easily be disconnected from
the mains.
1.5 Operation, environment
DANGER!
Never use the device in potentially explosive environments where
volatile solvents (alcohol, petrol, etc.) and flammable anaesthetics are in
use.
WARNING!
• The device must be switched off after every use. Otherwise there is
a risk of overheating when a protective dust cover is used.
• This device must not be operated near of high frequency surgical
equipment and the radio frequency shielded room of a medical
electrical system for magnetic resonance imaging, where the
intensity of electromagnetic disturbances is high.
• Portable radio frequency communications equipment (including
peripherals such as antenna cables and external antennas) should
be used no closer than 30 cm (12 inches) to any part of the device,
including cables specified by Haag-Streit. Otherwise, degradation of
the performance of this device could result.
NOTE!
• This device must only be operated by qualified personnel. The
owner is responsible for their training.
• This device may only be used in accordance with the instructions in
the 'Intended purpose / intended use' chapter.
• If unexpected disturbances are observed which manifest themselves
as communication problems between the imaging module and the
EyeSuite software, the cause could be a cell phone or a radio
frequency telephone in the immediate vicinity to the slit lamp or
power supply. Increase the distance to the unit until the interference
disappears.
•The communication between imaging module and PC may also be
disturbed or interrupted, if the device is exposed to a mains power
supply delivering excessively transient disturbances or short voltage
interruptions. If this happens, the USB connector needs to be
disconnected for a short time or the PC needs to be restarted.
1.6 Light toxicity
WARNING!
• The light from this device may be dangerous. The risk of eye
damage increases with the exposure time. An exposure time with
this device at maximum intensity of longer than 131 seconds
exceeds the guideline value for a risk.
• As extended, intensive illumination can damage the retina, the use
of the device in the examination of the eye should not be prolonged
unnecessarily. The illumination of this slit lamp emits a radiation in
the range between 400 and 750 nm. Detailed information on the
radiation can be provided on request.
• The retinal dose for a photochemical risk is composed of the product
of the radiance and the exposure time. If the radiance is halved, the
time until the exposure time limit value is reached will double
accordingly. To date, no acute, optical radiation hazard has been
detected in slit lamps. Nevertheless, we recommend keeping the
intensity of the light reaching the patient's retina to the minimum
possible for the respective diagnosis. Children, people with aphakia
and people suffering from eye conditions are most at risk. An
increased risk may also occur if the retina is exposed to the same or

2Intended purpose / intended use
A slit lamp biomicroscope is intended for use in eye examination. It is used to aid in
the diagnosis and documentation of diseases or trauma which affect the structural
properties of the eye.
2.1 Device description
The devices of the slit lamp are made up of:
• Stereo biomicroscope
• Slit illumination
• Instrument base
• Headrest and chin rest
The illumination system and a biomicroscope are mounted to an instrument base
operated by joystick. The single joystick allows horizontal and vertical displacement
of the slit lamp across the examination table. Both elements, the illumination system
and the biomicroscope, can be swiveled progressively across the pivot,
independently of one another.
A sturdy headrest is attached to the table. Both the table and the chin rest are
adjustable in height to provide a comfortable, yet sturdy examination position to the
patient, outside of the device's range of motion. As this device operates non-
invasively it only comes into contact with the patient at the chin rest and forehead
band.
2.1.1 Intended users
Users are qualified medical professionals such as ophthalmologists, optometrists,
opticians, nurses and researchers or other qualified specialists as permitted by local
legislation.
2.2 Medical purpose
This device has the following medical purpose:
• Diagnosis and monitoring of diseases of the anterior segment of the eye
• Diagnosis and monitoring of injuries of the anterior segment of the eye
• Investigation of the anatomy and physiological or pathological state of the
anterior segment of the eye
2.2.1 Indications
The use of the slit lamp is indicated for the following medical conditions:
• Local and systemic diseases affecting the eye
• Lesions and defects of the anterior segment
• Acute infections and inflammations
• Presence of intraocular foreign bodies
• Other traumata of the eye
2.2.2 Part of the body
The slit lamp is intended for the examination of the human eye, specifically the
anterior segment of the eye (i.e., lids, lashes, conjunctiva, cornea, anterior chamber,
iris, and lens).
2.2.3 Patient population
This device is intended for use on human patients with the physical ability to sit in
front of a slit lamp with their head resting against the headrest in a steady position
and the mental ability to follow instructions.
2.2.4 Contraindications
There are no known contraindications.
2.3 Principles of operation
• The slit lamp implements the principle of focal illumination: The focal point of the
microscope and the illumination coincide.
• The microscope arm and the illumination arm are mounted on an instrument
base: Both can be swivelled independently around the same vertical axis.
• The instrument base can be moved in all three axes.
• When illuminating transparent media with a narrow, sharp slit, an 'optical
section' can be magnified and viewed through the microscope.
• The patient's head is fixed to a height-adjustable headrest holder so that the
examination can be carried out quickly and as comfortably as possible for both
doctor and patient.

2.3.1 Operating environment
The slit lamp is intended to be used in professional health care facilities such as
hospitals, physician's, optometrist's and optician's practices. For optimal use of the
slit lamp, the ambient lighting should be attenuated to improve image contrast. In
case of transillumination of the iris or for viewing details at great magnification at a
narrow slit, it may be necessary to completely darken the room.
2.4 Clinical benefit
The use of the slit lamp allows for the systematic examination of the eye under
magnification, thus permitting the diagnoses of pathologies that may have otherwise
remained unidentified and could have lead to blindness if left untreated.
The clinical benefits of the product outweigh the remaining residual risks to the
patient.
3Introduction
The slit lamp consists of an illumination and a binocular microscope. The instrument
base can be used to move the entire device in front of the eyes. The illumination
offers a large number of setting options to make the practically invisible areas in the
eye visible. There is also a range of accessories available for the slit lamp to allow
special diagnosis possibilities in addition to the general examinations.

'10'.
6Operation
6.1 Setting the eyepieces
NOTE!
The eyepieces must be individually set prior to the first examination in
accordance with the refraction of the examiner. Insert the adjusting pin
(92) provided in place of the protective cover (93) and turn its black
projection surface at a right angle to the microscope axis. Return the
illumination and microscope to the central position (0°).
92. Adjusting pin
93. Protective cover
94. Sliding occluders
• Each eyepiece should be set individually by turning the knurled ocular refraction
ring with dioptre scale until the projected slit can be seen in focus. The setting is
performed from the (+) to the (-) side at low magnification.
• The sliding occluders (94) are used to set the correct working distance for the
examiner from the eyepiece.
• Examiners who do not wear glasses: Pull the occluders out as far as they will
go.
• Examiners who do wear glasses: Push the occluders in as far as they will go.
6.2 Field of view
WARNING!
The images and videos should only be used for documentation
purposes. Only the image in the eyepiece may be used for diagnosis.

6.3 White balance
The image quality is dependent on the correct calibration of the color tones to the
respective slit lamp illumination. We recommend performing a white balance in order
to improve the image quality and achieve a realistic color reproduction.
6.3.1 Slit lamp preparation
1. Turn the slit lamp on.
2. Filter position 'open' (no filter).
3. Select a 16 × magnification.
4. Completely open the slit diaphragm.
5. Connect the diffuser upstream.

6. Position the Haag-Streit greycard in front of the slit lamp and use it for
focusing.
7. The brightness of the slit lamp's illumination should be set in such a way that
the greycard's structure is clearly discernible.
6.3.2 Conducting a white balance
1. Start the 'EyeSuite Imaging' software
2. Activate the intensity auto mode
3. Open the 'White balance' application
4. Start the 'White balance' by activating the 'Calibration' function
NOTE!
To achieve an optimal result during the white balance, the image must
be homogeneously illuminated.

6.4 Software / Help menu / Error messages
The software is described in the EyeSuite Imaging instruction for use.
WARNING!
The software must be installed by trained personnel in accordance with
separate installation instructions.
6.5 Preparing the patient
• In order to attain a solid basis for the forehead and chin to rest on, the table
height should be selected such that the patient sits bent over forward.
• To ensure that only the part of the eye being examined is illuminated, the slit
height should be set accordingly in order to avoid distracting streaking of light.
• Applied parts which come into contact with the patient (headrest) should be
disinfected prior to every use (see instructions for use 'Headrest').
• After each examination, the LED illumination must be switched off via the
release module. See chapter "Decommissioning".
6.6 Operating the device
WARNING!
• Before every examination, check that the automatic left to right
detection works correctly from the release module!
• The device must be switched off after every use. Otherwise there is
a risk of overheating when a protective dust cover is used.
• Use the turn screw (A) to set the chin rest (B) so that the patient’s eyes are at
the same height as the black mark (C) on the sides of the headrest.
• Set the eyepieces (22) in accordance with the examiner’s refraction by turning
the knurled rings and set the eye distance.
• Switch on the illumination by turning the switch on the power supply.
• Adjust the height of the slit lamp by turning the control lever (30) until the light
beam and microscope axis are at eye level.
• The magnification of the stereo microscope is changed using the magnification
changer (100).
• The rigid control lever (30) gently inclined towards the examiner can be used to
push the entire device until the slit appears approximately focused on the

cornea. This initial setting is verified with the naked eye. Fine tuning is
performed by tilting the control lever while observing via the stereo microscope
(21).
• The slit width is set left or right with the rotating knob (28), as is the angle
between the stereo microscope and illumination.
• The slit image can be set vertically, horizontally or diagonally as required by
turning the illumination facility on the handle (5) (locking points at 45°, 90° and
135°; stops at 0° and 180°; scale in 5° increments).
• To ensure that unimpeded binocular fundus examination is also possible at
lateral angles of between 3° and 10°, a short mirror (8) is used, the illumination
turned 90° using the setting screw (5) and tilted in 5° steps using the latch (27),
and the illumination and microscope turned to the central position (0°).
• Front lenses and contact lenses are used to examine the ocular fundus.
Diffuse illumination:
Connecting the diffusor (9) upstream creates diffused illumination. This allows
monitoring of the overview and can be used to capture the overview with an imaging
module.
Indirect illumination:
For observation in regredient light (indirect illumination), the centring screw (25) is
loosened in order to move the slit image out of the centre of the visual field.
Tightening the screw centres the slit image again.
Slit tilting:
The latch (27) can be used to tilt the illumination in 5° steps. This creates an angled
light beam during horizontal slit orientation. Tilting the slit enables reflex-free
examination with contact lenses (fundus and gonioscopy) and magnifying lenses.

h. Blue filter
6.8 Fixation star
• Turning the diaphragm disc as far as it will go to the left switches
on the fixation star and the symbol 'S' appears in the window. In
some examinations of the fundus, this star is projected onto the
ocular fundus and is also visible to the patient, who is asked to
focus on the centre hole of the star. This allows the examiner to
see where the patient's vision is most focused.
• A typical use of the fixation star is close to the macula during
laser treatment. Similarly, it is also possible to identify
microstrabismus with the projection of the fixation star. The
fixation star is usually used with an upstream red removal filter.

6.10 Reduced operation
To guarantee a long service life of the light sources, the output of the background
illumination is reduced slightly once the maximum operating temperature is reached.
After a short cooling time, the full output can be used again. This operating state is
only achieved if both light sources remain switched on together for a prolonged
period and are therefore outside the specified temperature range.
