1. INDICATIONS FOR USE
This device is intended to be used only by suitably trained and authorised healthcare
professionals.
CAUTION: Federal Law restricts this device to sale by or on the order of a
physician or practitioner.
Intended use / purpose of instrument
The Keeler Slit Lamp facilitates an examination of the anterior segment, or frontal structures
and posterior segment, of the human eye, which includes the eyelid, sclera, conjunctiva, iris,
natural crystalline lens and cornea.The binocular slit-lamp provides stereoscopic magnified
view of the eye structures in detail, enabling anatomical diagnoses to be made for a variety of
eye conditions.
Brief description of the instrument
This Keeler Slit Lamp can either be mounted onto a custom table top supplied by Keeler or can
be mounted on a third parties table top (refraction unit) by suitably trained technicians.
The Keeler Slit Lamp consists of 5 assemblies; illumination tower; observation system; XYZ
translation base; chinrest assembly and a table top with power supply and accessory drawer.
The light intensity is controlled by a variable rheostat located on the XYZ translation base.
There are a number of selectable filters allowing the user to control the characteristics of the
examination light.
2. SAFETY
2.1 PHOTOTOXICITY
CAUTION: 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 81 seconds.
While no acute optical radiation hazards have been identified for slit
lamps, 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.
Keeler Ltd shall on request, provide the user with a graph showing the
relative spectral output of the instrument.

2.2 WARNINGS AND CAUTIONS
Please note that the proper and safe functioning of our instruments is only guaranteed if
both the instruments and their accessories are exclusively from Keeler Ltd. The use of other
accessories may result in increased electromagnetic emissions or reduced electromagnetic
immunity of the device and may lead to incorrect operation.
Observe the following prescriptions in order to ensure safe operation of the instrument.
WARNINGS
• Never use the instrument if visibly damaged and periodically inspect it for signs of damage
or misuse.
• Check your Keeler product for signs of transport / storage damage prior to use.
• Do not use in the presence of flammable gases / liquids, or in an oxygen rich environment.
• US Federal Law restricts this device to sale by or on the order of a physician or practitioner.
• This device is intended to be used only by suitably trained and authorised healthcare
professionals.
• This product should not be immersed in fluid.
• Repairs and modifications to the instrument must be made only by the specialized
technicians of the manufacturer’s Technical Service Centre or by personnel trained and
authorised by the manufacturer. The manufacturer declines any and all responsibility for
loss and/or damages resulting from unauthorised repairs; furthermore, any such actions
will invalidate the warranty.
• The power switch and mains plug are the means of isolating the device from the mains
supply - ensure both the power switch and mains plug are accessible at all times.
• Do not position the equipment so that is difficult to press the power switch or remove the
mains plug from the wall socket.
• Refraction stand variants or adaptors should only be used in combination with EN/IEC
60601-1 and EN/IEC 60601-1-2 compliant power supplies and devices.
• Route power cords safely to eliminate risk of tripping or damage to user.
• Before any cleaning of the instrument or the base unit ensure the power lead is
disconnected.
• LEDs can reach high temperatures in use – allow to cool before handling.
• Do not exceed maximum recommended exposure time.
• Should the instrument suffer shocks (for example, should it accidentally fall), and the
optical system or the illumination system are damaged it may be necessary to return the
instrument to the manufacturer for repair.

• After removal of the LED, do not touch the Slit Lamp LED electrical contacts and patient
simultaneously.
• The owner of the instrument is responsible for training personnel in its correct use.
• Ensure the instrument or instrument table is placed on a level and stable surface.
• Use only genuine Keeler approved parts and accessories or device safety and performance
may be compromised.
• Shut down after every use. In case the dust cover is used: risk of overheating.
• For indoor use only (protect from moisture).
• Electrical equipment can be affected by electromagnetic interference. If this occurs whilst
using this equipment, switch the unit off and reposition.
• Do not touch accessible connectors and the patient simultaneously.
• Before use, the Slit Lamp should be allowed to adjust to the ambient room temperature for
several hours. This is especially important when the unit has been stored or transported in a
cold environment; this can cause severe condensation to develop on the optical elements.

2.3 CONTRAINDICATION
There is no restriction to patient population this device can be used with other than those
outlined in the contra-indications stated below.
Slit lamps can produce discomfort in some photophobic patients due to the high illumination.
Additionally patients must be co-operative and capable of sitting upright for the duration of
the examination, therefore the technique may not be suitable for patients who are unable to sit
upright for long periods of time or those with limited neck and back mobility.
3. CLEANING AND DISINFECTION INSTRUCTIONS
Before any cleaning of the instrument or the base unit, ensure the power
lead is disconnected.
Only manual non-immersion cleaning as described should be used for this instrument. Do not
autoclave or immerse in cleaning fluids. Always disconnect power supply from source before
cleaning.
1. Wipe the external surface with a clean absorbent, non-shedding cloth dampened with
de-ionised water / detergent solution (2% detergent by volume) or water / isopropyl
alcohol solution (70% IPA by volume). Avoid optical surfaces.
2. Ensure that excess solution does not enter the instrument. Use caution to ensure cloth is
not saturated with solution.

5. ASSEMBLY
Your Keeler Slit Lamp has been designed to fit on to an electric insulated medical table base or on
to an electric insulated and fire resistant medical table top, e.g. a refraction stand or combi unit.
Take care when unpacking your Slit Lamp that you do not accidentally damage or discard any
of the contents.
Leave the Slit Lamp in the packing for several hours after delivery before
unpacking to reduce the risk of condensation forming.
Keeler Slit Lamps can be fitted to most Refraction Stands / Combi units. Keeler advises that this
shall be carried out by a suitably trained technicians to ensure performance and safety are not
affected.
The refraction stand, combi unit or table leg must be IEC 60601-1
compliant.
If you are fitting or have fitted your Slit Lamp to a medical or Keeler table leg / base ensure it is
situated on a firm and level floor.
If the table leg / base has castors ensure the following before moving it to another location:
1. The table is at its lowest position.
2. The power cord is removed.
3. The Slit Lamp arm and base locking knobs are tightened.
4. The runner covers are securely located.
5. The system is moved by grasping it at its lowest practical point.
5.1 TABLE TOP AND BASE ASSEMBLY PROCEDURE
1. Attach the Slit Lamp table top to your table leg using the M6 x 20mm screws and
washers. Note that the power supply and accessory drawer should face the operator.
The security of the fitment of the table top to the table leg is critical for
patient and Slit Lamp safety
2. Using the wrench provided, fit the headrest assembly to the tabletop using the hex bolts
and washers. The headrest assembly locates on the underside of the tabletop. Take care
not to over tighten the hex bolts.
3. Attach the patient grab handles (7) to the headrest assembly.
4. Place the Slit Lamp base on the runners. Ensure that the wheels are in line with each
other. Check that the guide wheels are tight.
5. Fit the runner covers to the runners by gently sliding them inwards, towards each other.
