CAUTION
Ensuring the Safety of Patients and Operators
When moving the instrument body up and down, be careful not to bump it against the patient's face.
The patient may be injured.
This instrument should only be used by skilled operators.
To prevent the instrument from tipping over or falling and to avoid injury, do not install the
instrument on an uneven, unsteady or sloping surface.
Do not put your hand between the mounting arm and the instrument. Your hand may be pinched.
To avoid injury due to contact, do not bring the patient's face close to the near-point rod.
To avoid injury caused by pinching when moving the monitor unit, do not place your hand
between the monitor unit and the main unit.
Install the devices (RM, CL and others), which will be connected with the optional accessories,
out of the CV-5000 patient's environment.
Do not to connect additional a power strip (it shall be not only in patient environment also in
outside of patient environment).
Install the visual acuity chart out of the CV-5000 patient's environment.
Install the devices (RM, CL and others) to be connected out of the CV-5000 patient's environment.
When tilting the instrument downward, place the measuring head away from the patient to pre-
vent him/her from being injured by colliding against it.
Do not tilt the instrument downward while the near-point rod is pulled down. The near-point rod
may hit the instrument or desk and damage the instrument.
To avoid injury caused by pinching when moving the monitor unit of the 1Dial Controller , do
not place your hand between the monitor unit and the controller unit.
• When you connect this instrument on the personal computer connected to a network, ensure
security properly in order to prevent the infection with computer virus, leak of information
and other troubles.

the patient sees chart almost equally through the CC lens having red and green frames.
Press the [A] switch on the controller unit. The system returns to the cylinder axis measurement.
5.1.6 SMART CROSS TEST
Measure astigmatism accurately with the Jackson cross cylinder lens semi-automatically.
In general, the cross cylinder test forces the patient to compare
the targets having slightly different powers repeatedly. Consequently the patient becomes tired from stress.
In the smart cross test, the cylinder power and axis, which are
input as the initial values, are regarded as the "Temporary-real
values". By referring to the temporary-real axis value, the system calculates the axis whose view is most different on the front
and rear of the cross cylinder lens. First, the patient's comparison begins with this calculated axis. Then, the axis is moved to
the opposite side against the temporary real value and the system asks the patient to compare the views of the chart. The
axis movement is automatically conducted. As the move width
is made smaller, the system searches for the "Real cylinder
axis". This test is performed to reduce the fatigue on the
patient.
At the final stage of the axis test, the type of the used cross cylinder lens is automatically changed from "0.50D" to "0.25D"
to reduce uneasiness of the patient. The test finishes with a
lower cross-cylinder power resulting in a clearer end result and
less fatigue for the patient.
1 Prepare for the test.
In some cases, measurement cannot be done. Before beginning the test, set the cylinder power and axis measured objectively.

is seen by both eyes as shown below. In addition, the upper half is seen by the right eye
and the lower half, by the left eye.
When the patient does not have horizontal aniseikonia, he/she sees the upper and lower
images in the same size.

yes, have the patient view the opening of the upper and lower images and answer how
much the lines are different in relation to each other.
When the disparity at one side is about half a line, the patient should answer "half a line".
When it is about one line, the patient should answer "one line".
When the upper image is larger than the lower one by one line, touch the [U>D 1.0] button to record the value.
When the upper image is larger than the lower one by half a line, touch the [U>D 0.5]
button to record the value.
When the lower image is larger than the upper one by one line, touch the [U<D 1.0] button to record the value.

button to record the value.
When the upper and lower images are the same size, touch the [U=D] button to record
the value.
When disparity of half a line is recognized, the magnification is different by 3.5%
between the images of the right and left eyes. When disparity of one line is recognized,
it is different by 7.0%.

5.3.6 COINCIDENCE TEST (V)
When the patient sees the image in the vertical direction after correction, the image size seen by
the right eye may be different from the image seen by the left eye. In this test, check if the image
size is different between the right and left eyes.
If there is a difference of one line (7%) or more, it is recommended to recheck the correction value.
1 Prepare for the test.
If heterophoria is not corrected, the patient's eye may not be refined properly. Before
this test, correct heterophoria.
For phoria test, refer to "5.2.1 PHORIA TEST (POL. CROSS)" on P.68.

2 Check how the chart is seen.
When the patient sees the test chart by each eye through the red and green auxiliary
lenses, the three green shapes are seen by the left eye and the two red shapes are seen
by the right eye.
Chart seen by left eye Chart seen by right eye
When the patient sees the chart with both eyes at the same time, there are five types of
the conditions as described below.
[4 Dots]
When the patient sees the four shapes, he/she does not have strabismus or he/she has
abnormal concordance.
The lowest white shape is seen in red, green or a mix of red and green. When the lowest shape is seen in red, the right eye is superior. When it is seen in green, the left eye
is superior. When it is seen in the mixed color, the right and left eyes are balanced.
[2 Red]
When the patient sees the two red shapes, the left eye is suppressed if he/she sees an
object with both eyes.
[3 Green]
When the patient sees the three green shapes, the right eye is suppressed if he/she
sees an object with both eyes.
[5 Dots]
When the patient sees the two red shapes and three green shapes, the patient has strabismus.
[2R 3G Alter]
When the patient sees the red and green shapes alternately, he/she has alternating suppression.

5.3.8 SHEARD'S CRITERIA
Sheard's criteria is a theory that, to keep normal binocular function, the extra convergence or divergence that is twice as large
as heterophoria or more is necessary.
In this test, check if the patient has extra convergence or divergence that meets Sheard's criteria according to the measured
heterophoria.
If there is extra convergence or divergence that meets Sheard's
criteria, it is judged that prism prescription is not necessary.
If this isn’t the case, the program calculates the prism quantity
that makes up for the insufficiency automatically.
1 Prepare for the test.
This test must be executed after the horizontal phoria has already been measured.
Before this test, measure horizontal phoria.
For the horizontal phoria test, refer to "5.2.4 HORIZONTAL PHORIA MEASUREMENT (PRISM SEPARATION)" on P.74.
2 Touch the [Sheard] button.
While the phoria test is being executed, the [Sheard] button is displayed as a function
button.
This [sheard] button is valid when horizontal phoria is measured. After the horizontal
phoria has been measured, touch this button.

3 Measure convergence or divergence.
The program automatically judges that the system should
measure divergence if the measured heterophoria is esophoria and convergence if it is exophoira. The program
guides measurement.
Have the patient view the chart where characters are
arranged on one vertical line. Instruct the patient to respond when the blurred characters are seen or when the characters are seen on two lines. Then, turn the dial slowly in
the direction indicated by Dial Navigation.
Each time you turn the dial, the recommended prism value is changed in "Mini Help" as
shown in the right example.
If the prism value is "0" and the patient does not say "I see the blurred characters" or "I
see the characters on two lines", there are extra convergence or divergence that meets
Sheard's criteria.
The measurement is finished.
However, if the patient says "I see the blurred characters" or "I see the characters on two
lines" before the recommended prism value is "0", return the dial to the preceding status
and finish the measurement.
The recommended prism value displayed in "Mini Help" is the prism correction value
required to meet Sheard's criteria.
4 Record the result.
After the measurement, touch the [Record] button to record the result. The Sheard's criteria test is finished.
