Introduction
Congratulations on the purchase of your new Xcel®455 Slit Lamp from Reichert Technologies®.
This user’s guide is designed as a training and reference manual for the operation and maintenance
of the instrument. We recommend that you read it carefully prior to use and follow the instructions to
ensure optimum performance of your new instrument. Properly trained eyecare professionals such as
ophthalmologists, optometrists, opticians and eye care technicians should operate this instrument.
Please retain this manual for future reference and to share with other users. Additional copies can be
obtained from your authorized Reichert®distributor or from the Reichert customer service department at:
Tel: [phone]
Fax: [phone]
Email: [email protected]
Indications for use
The Xcel 455 Slit Lamp is an AC-powered slit lamp biomicroscope that is intended for use in examining the
anterior eye segment, from the corneal epithelium to the posterior capsule. It is used to aid in the diagnosis
of diseases or trauma, which affect the structural properties of the anterior segment of the eye.
Contraindications
None.
Phototoxicity Information
Because prolonged intense light exposure can damage the retina, the use of the device for ocular examination
should not be unnecessarily prolonged, and the brightness setting should not exceed what is needed to
provide clear visualization of the target structures. This device should be used with filters that eliminate UV
radiation (< 400 nm) and, whenever possible, filters that eliminate short-wavelength blue light (< 420 nm).
The retinal exposure dose for a photochemical hazard is a product of the radiance and the exposure time. If
the value of radiance were reduced in half, twice the time would be needed to reach the maximum exposure
limit.
While no acute optical radiation hazards have been identified for slit lamps, it is recommended that the intensity
of light directed into the patient’s eye be limited to the minimum level which is necessary for diagnosis. Infants,
aphakes and persons with diseased eyes will be at greater risk. The risk may also be increased if the person
being examined has had any exposure with the same instrument or any other ophthalmic instrument using a
visible light source during the previous 24 hours. This will apply particularly if the eye has been exposed to
retinal photography.

CABLES FOR THE ACCESSORIES SUCH THAT THEY DO
NOT PRESENT A TRIPPING HAZARD TO THE EXAMINER
OR A DANGER TO THE PATIENT.
WARNING: POSITION THIS INSTRUMENT SO THAT IT
IS NOT DIFFICULT TO OPERATE THE DISCONNECTION
DEVICE (PLUG).
1. After the unit is in its secure location, apply the
correct input voltage to the instrument using the

Instructions for Use
Operation
1. Turn on the power using the On/Off switch located
on the front of the Power Supply Assembly.
Brightness can be adjusted by rotating the
Illumination Level Control Knob.
Refer to Figure SU-14.
Note: The maximum intensity setting is for
intermittent use only. Continuous use will
shorten the lamp life.
2. Insert the Focusing Rod in the pivot post of the
instrument body to make rough PD and focus
adjustments. Refer to Figure IN-1.
3. Position the light onto the flat surface of the
Focusing Rod and adjust the pupillary distance
and focus of the eyepieces to suit the needs of the
operator.
4. Using the Slit Width Knobs, adjust the projected
slit so that the thinnest slit is shown on the
Focusing Rod. Refer to Figure IN-2.
Note: The thinnest slit will allow for greater accuracy.
5. Remove the Focusing Rod.
6. To position a patient, adjust the chinrest height
by turning the Chinrest Elevation Handle on the
post of the Chin Rest Assembly until the patient’s
canthus is in line with the Canthus Mark on the
chin rest post. Refer to Figures IN-2 and IN-3.
7. Microscope elevation is adjusted by rotating the
joystick and observing the slit image through the
Microscope Assembly until the slit is centered on
the patient's cornea. Refer to Figure IN-4.
8. Move the slit lamp with the joystick held firmly
and slightly angled toward the patient, until the slit
appears sharply on the cornea.
Note: The accuracy of this rough adjustment should
be checked by the naked eye. The ne
adjustment is performed while observing the
slit through the microscope.
9. Tilt the joystick, which is now held lightly at its
upper end, until the slit appears sharply at the
depth of the eye which is to be observed.
10. The horizontal motion of the base can be locked
by tightening the base locking screw. Refer to
Figure IN-4.
Note: Lock the base whenever the lamp is not in use.

Slit Rotation
By grasping the Slit Rotation/Length Knob, the lamp
housing can be rotated. This, in turn, rotates the slit
from vertical to horizontal in either direction. The slit
positions are click-stopped in 45° increments and
stopped at 0° and 180° and is indicated by the scale.
Refer to Figure IN-9.
Illumination Inclination
The Illumination Assembly can be inclined in the
horizontal plane in 5° steps for a total of 20°. Tilt the
Illumination Assembly by depressing the Inclination
Latch Release and pulling the base of the Illumination
Assembly toward the operator. Refer to Figure IN-10.
Slit Centration
When the centering screw is loosened, the slit can
be scanned away from the center of the field of
vision for retro-illumination, scleral scatter, etc. The
slit image is centered again by tightening the screw.
