• 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.
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
a similar device with a visible light source within 24 hours. This
applies, in particular, if the retina has been photographed with a
flashbulb in advance.
1.7 Disinfection
NOTE!
The device can, but does not need to be disinfected. For more
information, please refer to the 'Maintenance' chapter.

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.

4 Device assembly / installation
WARNING!
•Do not modify this device without authorization of the manufacturer.
Installation and repairs may only be performed by trained
specialists.
• Contact your Haag-Streit representative for installation, repairs and
modification work on the system. The contact details are available at
www.haag-streit.com.
• Only original Haag-Streit spare parts may be used.
4.1 Microscope and illumination
• The slit lamp is packaged and delivered fully assembled. The transport safety
devices must be removed prior to commissioning.
• Fix the breath shield (35) in place by fastening the knurled screw (34) on the
inside of the bearer arm.
4.2 Power supply
NOTE!
• Observe the respective Haag-Streit instructions for use. For further
information, please contact your Haag-Streit representative.
•This device must only be operated with PS-LED and PS-LED HSM
901 Haag-Streit power supplies and the RM02 release module.
4.3 Instrument base with weight compensation facility
The weight of additional accessories mounted on the microscope can be
compensated using counterbalance springs. This keeps the height adjustment of the
slit lamp easy.
4.4 Setting the weight compensation facility
Turn the control lever (60) to its lowest position and then loosen it slightly a quarter
turn. Turn the microscope and illumination to the side. Apply 1−3 springs depending
on the accessory.
4.5 Switching on the compensation facility
Turn anticlockwise until the screws (59) are completely released.
4.6 Switching off the compensation facility
Turn clockwise until you meet resistance. Verify whether the microscope arm
springs back downwards if you push it upwards with your hand. This will only
happen if the load is already at maximum. Generally, as many counterbalance
springs should be deactivated as necessary until this spring action occurs. The
weight compensation facility is set correctly once the illumination and microscope
with the mounted accessories weigh slightly more than the counterbalance springs.
4.7 Regulating the clearance of the slit width controls
The small screw in the centre of the right control knob
(83) allows you to regulate the friction of the turning
movement of these adjusting knobs. Turning it slightly
to the right (in) makes it harder, turning it left (out)
makes it easier. It should at least be set so hard that
the slit cannot close on its own.
5 Commissioning
The device can be switched on and off using the mains power switch on the power
supply. The green lamp in the rocker switch lights up when the device is switched
on.
5.1 Switching on the device
• Connect the power supply to the mains and press the rocker switch. The green
lamp in the rocker switch lights up when the device is switched on.
• Turn the rotating knob on the illumination control to a position between '1' and
'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 provided focus
test rod (41) in place of the protective cover (42) and turn its black
projection surface at a right angle to the microscope axis. Return the
illumination and microscope to the central position (0°).
41. Test rod
42. Protective cover
43. Sliding occluders
41
42
43
• 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 required pupil distance should then be set on the microscope.
• The sliding occluders (43) 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 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').
• The slit lamp must be switched off after every examination in accordance with
the 'Decommissioning' chapter.
6.3 Operating the device
WARNING!
The device must be switched off after every use. Otherwise there is a
risk of overheating when a protective dust cover is employed.
• Use the turn screw (7) to set the chin rest (6) in such a way that the patient’s
eyes are at the same height as the black mark (4) on the sides of the headrest.
• Adjust the eyepieces (32) 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 (39) until the light
beam and microscope axis are at eye level.
• The magnification of the stereo microscope is changed using the magnification
changer (15).
• The rigid control lever (40) 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
(31).
• The slit width is set left or right with the rotating knob (21), as is the angle
between the stereo microscope and illumination.
• The slit image can be set vertically, horizontally or as diagonal as required by
turning the illumination facility on the handle (28) (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 (13) is used, the illumination
turned 90° using the locking screw (21) and tilted in 5° steps using the latch
(36), 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 (14) 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 (18)
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 (36) 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
6.5 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 during laser treatments close to
the macula. 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.

7 Decommissioning
The LED illumination can be switched off with the illumination controls. The power
supply remains switched on during this process and the switch lights up green. To
switch the system off completely, the rocker switch must be set to the 0 = 'OFF'
position. This creates a two-pole isolation from the mains.
NOTE!
Disconnect the power supply from the mains if you do not intend to use
it for an extended period of time.

10.6.4 Electromagnetic immunity environment tested (part 2)
Portable and mobile RF communications equipment should be used no closer to any part of this product, including cables, than the recommended separation distance
calculated from the equation applicable to the frequency of the transmitter.
These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people. Field strengths
from fixed transmitters, such as base stations for radio (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.
