5 1 INTRODUCTION
Congratulations on the purchase of your new eVO500/ eVO500D!
This instruction manual is designed as a training and reference manual for the operation and
maintenance of your instrument. We recommend that you read it carefully prior to use and
follow the instructions to ensure optimum performance of your new instrument.
Please retain this manual for future reference and to share with other users. Additional copies
can be obtained from your authorized LABOMED dealer or from the LABOMED service
department. Contact information is provided at the end of this manual.
LABOMED eVO500/ eVO500D Slit Lamp is an all-in-one digital ophthalmic instrument for
observation, measurement and diagnosis of Contact lens fitting, Anterior eye segment,
Cataract, Glaucoma, Retina etc.
Its optimally structured design also allows the eVO500/ eVO500D to be used in laser therapy;
this has been achieved by the possibility of operating the Slit projector in the central position
either with the left hand or right hand. The excellent transmission of the optical system
minimizes light loss during therapy. Together with the excellent image quality, this provides
ideal conditions for crisp, crystal clear images of even the finest structure.
Considering standard work procedures, the design of this system have been modified to carry
an in-builtcamera. The integrated module is optically corrected unit, to deliver the best results
in its class. An eVO500D also has a micro SD slot and an HD touch screen panel, which provides
you with an optimum, ergonomically corrected configurations and is low on fatigue while in use.
The perfection of the observation system along with an outstanding operating convenience
ideally complements each other. The outstanding benefits of this design include an effortless
operation, short working distance, comfortable arm and body posture, easy grip controls for the
sensitive setting of the Slit length, width and rotation. Using the joystick, you can control the
eVO500/ eVO500D quickly and precisely in all three coordinates and set it exactly in any
position with a quick action locks. The joystick also has a push button at the top which is very
easy to use to click photos and videos in eVO500D.
6 Its slit angle of incidence makes it easier to view the inner side by rotating the illumination arm
(0° - 90°), giving it a 3 dimensional rigid view of the eye interrelated with slit housing. It makes
and rotate the slit at its 0° - 180° position with fine click stop smooth movement option for the
corneal view, vertically/horizontally reducing or increasing the size of slit from 0-14mm.With the
continuous slit measurement of 1.5 to 11mm and variable fixed measurement at 0.5, 5, 8,
12mm it has enhanced red free, cobalt blue and heat absorbing filters.
The user expects the slit lamp microscope to provide optimum stereoscopic observation with
selectable magnification. The size of the field of view and the depth of field are expected to be
as large as possible, and there should be enough space in front of the microscope for
manipulation on the eye. eVO500/ eVO500D is a powerful instrument with 5 step magnification
(6.5x, 10x, 16x, 25x& 40x) in combination with a binocular straight head, 12.5x/16mm wide
field eyepieces (Diopter adjustment +/-6 ) and a smooth adjustable IPD 48.5-80mm.
An eVO500D slit lamp is designed for all digital imaging requirements. Its fatigueless
examination with integrated 5.0 mega pixels (1080p) digital module supporting, image
capturing and option of recording live on the screen panel in HD quality makes the job even
easier while performing examination on the spot. Coupled with an integrated capture button to
capture images and make videos which can often be useful to explain to the patient, findings or
the condition and fit of a contact lens during an examination. This saves time-consuming
theoretical explanations later. This modern technique is well suited for documentation,
information and educational purposes and due to its low weight. It does not impair the mobility
and ease of handling of the slit lamp.

Turn the power using the ON/OFF switch located on the front of the power supply.
Brightness can be adjusted by rotating the illumination level knob situated on the
microscope base.
NOTE: The maximum position is for intermittent use only.
Continuous use will
shorten lamp life.
2.
Insert the projection rod in the pivot post of the instrument body to make rough PD
and focus adjustments. Position the light onto the flat surface of the projection rod
and adjust the pupillary distance and focus of the eyepieces till a comfortable
viewing is obtained. Remove the projection rod.
3.
To position a patient, adjust the chinrest height by turning the control knob 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.
4.
Microscope elevation is adjusted by rotating the joystick and observing the Slit
image through the microscope until the slit is centered on the patient’s cornea.
5.
Move the Slit lamp with the joystick held firmly and slightly angled towards the
patient, until the slit appears sharply on the cornea. The accuracy of this rough
adjustment should be checked by the naked eye. The fine adjustment is performed
while observing the slit through the microscope.
6.
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. The horizontal motion of
the base can be locked by tightening the base locking screw. Lock the base
whenever the slit lamp is not in use.
7.
The slit width can be adjusted by rotating the slit width control knob on either sides
of the instrument.

12 9.
Magnification is altered by rotating the dial on the microscope head. The
magnification of each click stop position is engraved on the dial.
10. Three filters are provided for cool and comfortable view. This can be achieved by
rotating the filter dial.
An eVO500 is a basic and eVO500D is the high end model. So, technically what
separates evo500D from evo500 is the broad spectrum of optional accessories that
offer solutions best suited for the comfort level of both-the patient and the user of
the slit lamp. Following are the key features worth mentioning which makes an
eVO500D superior over its basic version eVO500.
1.
Mount the touch screen panel that allows the user to view live images. Use click
button provided on the joystick to capture images and record videos.
2.
Select the options on the touch screen panel as per your requirements. These
options are “Capture”, “Zoom In/Out” & “Exit”. A Capture option once selected
will show “Capture image” and “Capture Video”, this works only if the SD card is
inserted in the memory card slot. Exit selection will make all the options disappear
on the panel.
3.
Insert an SD card to capture live images and recording videos which can be used
later on to retrieve images and videos obtained for the patient with the slit lamp.
4.
A PixelPro* control software supports all the above features meant for eVO500D slit
lamp when attached with USB port.
