INTRODUCTION
Thank you for purchasing the TOPCON Compu-Vision CV-5000.
This instrument is used to measure refractive power of eyes and to test the binocular func-
tions.
There are two types in the CV-5000 model. One is CV-5000, in which you can perform the
prism refractive power test and cross cylinder (Auto Cross) test. The other is CV-5000 Lite,
in which you cannot perform these tests.
This instrument has the following features:
•The compact design enables you to see the patient's face.
•The target can be controlled by the controller for the main unit.
•The PD and the anterior eye alignment can be checked even in a dark optometry room.
This instruction manual outlines the Compu-Vision CV-5000, including the basic operation,
trouble shooting, maintenance and cleaning.
To ensure the best use of the instrument (safely and efficiently), carefully read "DISPLAY FOR
SAFE USE" and "SAFETY CAUTIONS" and then use the instrument correctly.
Keep the instruction manual at hand for future reference.
CAUTIONS FOR USE
Basic caution
When moving the instrument up and down or turning it, be careful not to bump it against the
patient's face.
[The patient may be injured.] Handle the CV-5000 using the top covers above the lens banks.
Do not open the covers. Ask the serviceman to repair the instrument.
[Injury may be caused by electric shock.]
Turn off the power switch and unplug the power cord first. Then, replace the fuse with the rated
one.
[Injury or fire may be caused by electric shock.]
Disposal
Dispose of the instrument according to local disposal and recycling laws.
[Warning]
Be careful not to bump the patient’s eyes or nose with the instrument during

PREPARATIONS
PREPARATIONS
ASSEMBLY/INSTALLATION OF NEAR-POINT ROD AND NEAR-POINT CARD
Insert the near-point card into the end of the near-point rod. The near-point card is designed to
slide on the near-point rod.
Insert the near-point rod into its holder and tighten the clamp screw securely. When the near-
point rod is not in use, set it upright. (Tighten the clamp screw securely.)
Install the near-point card toward the CV instrument in the direction where it can be bent.
INSTALLING THE FACE SHIELD AND FOREHEAD REST
The face shield is fixed by putting it on the face shield magnet properly.
To remove the forehead rest, as viewing from its side, pull it upward.
To mount the forehead rest, carry out the removing procedure reversely.
CAUTION To avoid injury due to contact, do not bring the face close to the near-
point rod.
NOTICE The near-point card must be bent in the set direction. Do not bend it
forcedly in the opposite direction. The near-point card may be broken.
NOTICE Install the near-point card to the near-point rod according to the seal,
which is adhered on the card to show its installation direction.

PREPARATIONS
LEVEL ADJUSTMENT
Before using the instrument, check if it is horizontal, using the level. If there are not bubbles
between two red lines, turn the leveling knob to make the instrument horizontal.
FIXING THE TILTED HEAD
By tilting the head in the near-point test, the instrument can be set in the proper position for the
real near-point test.
To tilt the head, loosen the tilt fixing lever of the instrument.
NOTICE Hold the PD unit when moving the head.
CAUTION
Do not tilt the head for the near-point test while the near-point rod is
inclined. The near-point rod may hit the instrument or desk to dam-
age the instrument.
CAUTION
When tilting the head for the near-point test, place the instrument
away from the patient to prevent him/her from being injured by collid-
ing against it.

17
PREPARATIONS
When the head is tilted to a desired angle, fix the lever.
The tilt fixing lever is a serration type. If the tilt fixing lever hits the instrument or the
mounting arm while it is loosened, adjust its position.
NOTICE Do not rotate the instrument while the tilt fixing lever is loosened. The
tilt fixing lever may hit the mounting arm to damage the instrument.
CAUTION Do not put your hand between the arm and the instrument. Your hand
may be pinched to cause injury.

PREPARATIONS
NEAR-POINT CARD
When the patient wears the multi-focal lenses, measure the eyeglass refractive power at near
distance. For installing the near-point rod and near-point card, refer to "ASSEMBLY/INSTAL-
LATION OF NEAR-POINT ROD AND NEAR-POINT CARD".
Incline the near-point rod until it stops. If the near-point rod is almost horizontal, the position is
the measuring position.
The scale of the near-point rod is graduated by the "cm" unit (15 ~ 70).
Values matching both end lines of the card holder indicate the distance between the eye and
the card.
Set the desired target on the near-point card attached to the card holder.
To set the target, turn the rotary part at the bottom of the card by your fingers. The target
appears in the sight window.
Target numbers of the near-point card and the contents are shown below.
(1) 40cm target VA 20/50-20/20
(2) Target for presbyopia
(3) Target for horizontal line
(4) Target for horizontal line (40cm target VA 20/20)
(5) Target for presbyopia (thin lines)
(6) 40cm target VA 20/200-20/60
(7) Target for astigmatism
(8) 40cm for VA 20/20
(9) Target for vertical line
(10) 67cm target VA 20/200-20/20
Target name on the patient side
When you stop turning the rotary part of the card at the position displayed as "Astigmatic
chart", the patient sees the target for astigmatism (astigmatic chart). (The target for astigma-
tism (astigmatic chart) is displayed in the sight window at the back side.)
CAUTION To avoid injury due to contact, do not bring the face close to the near-
point rod.
CAUTION
Do not tilt the head for the near-point test while the near-point rod is
inclined. The near-point rod may hit the instrument or desk to dam-
age the instrument.
NOTICE The near-point card must be bent in the set direction. Do not bend it
forcedly in the opposite direction. The near-point card may be broken.
