I. INTRODUCTION
1. OUTLINE OF PRODUCT
CS550 is an automatic visual acuity system, stand-alone type, which displays broad range of charts, based
on LCD panel, including red /green for the eye optometry.
The chart rotation for CS550 can be performed by either wired or wireless remote control or by external
devices by control box of Digital Phoropter.
Unlike existing chart projector, CS550 is able to provide wider range of charts (more than 100 kinds of
general and special charts) on LCD panel and the product can be adjusted at the level of the patients for
precise examination.

VII. TEST METHOD
Division Description Test method
Orthoptic test (Binocular balance)
The test is for
synchronizing the visual
function with both left
and right eye by using
Red/Green filter.
1. Show binocular test types to a patient.
2. Let a patient wear Red/Green glasses (right eye = red
filter, left eye = green filter).
3. Ask a patient which line of both above and below lines is
shown much clearer. If above line is clearer +0.25D as
much should be added at a right eye. On the contrary, if
below line is clearer +0.25D as much should be added at a
left eye.
Orthoptic test (Red/Green binocular
balance)
The test is for adjusting
to the balance of both
right and left eye by
using prism glasses.
1. Show Red/Green binocular balance test type to a patient.
2. Let the patient wear prism glasses in a left eye (left =
Down, right = Up).
3. Ask a patient which one is clearer of green circle and red
circle on Red/Green test type. If the patient saw the red
circle clearer, +0.25D should be added in a left eye until he
can see that Red/Green circles are just alike. But if the
green circle was shown clearer, +0.25D should be added in
a left eye, until the circles are equally shown.
Orthoptic test (Worth 4 dots)
The test is for
measuring which eye is
better shown of left &
right eyes, by using
Red/Green filter.
1. Show Worth 4 dots test type.
2. Let a patient wear Red/Green glasses (right eye = red
filter,left eye = green filter).
The patient sees mark in a right eye and mark in a leftⓐ ⓑ
eye on Worth 4 dots test type. The binocular condition
would be ideal, if the patient could see mark.ⓒ
3. Judge a patient's binocular function as below, while
asking him how the type is seen.
Left eye's suppressionⓐ
> Left eye would be suppressed, if
a patient saw only 2 red lights.
Right eye's suppressionⓑ
> Right eye would be suppressed, if
a patient saw only 3 green lights.
Blendingⓒ
> If a patient saw 4 dots, binocular
function would be normal.
Diplopiaⓓ
> If a patient saw 5 dots, he/she
would have diplopia.

eye using Red/Green filter.
1. Show aniseikonia test type.
2. Let a patient wear Red/Green glasses (right eye =
red filter, left eye = green filter). The patient sees
fixation target and “]” in a right eye and fixation
target and “[” in a left eye.
3. Ask a patient if he can see borders that have in
between interval. Also asking if a left and a right
border are alike or which one is shown smaller than
the other.
The patient's binocular condition ⓐ
is left > right and right eye < left
eye.
The patient's binocular condition ⓑ
is left < right and right eye > left
eye.
4. The reason of aniseikonia is heteropsia(when
diopter's difference of both a right and a left eye is too
big).
And if the result were an axial heteropsia,glasses
would be prescribed and if a refractive heteropsia,
contact lenses prescribed.

Division Description Test method
Phoria test (Cross phoria)
This test is for
testing
horizontal/vertical
phoria of right or
left eye by using
Red/Green filter.
1. Show cross phoria test type to a patient.
2. Let a patient wear Red/Green glasses (right eye = red filter, left
eye = green filter).
The patient sees « » mark in a right eye and « » mark in a
left eye on cross phoria test type. The binocular condition would be
ideal, if the patient could see « ». mark.
Patient's
visual status
Phoria Method
Esophoriaⓐ
Add B.O prism until a vertical line
can come to the center of a
horizontal line.
Exophoriaⓑ
Add B.I prism until a vertical line can
come to the center of a horizontal
line.
Left eye'sⓒ
hyperphoria
Add B.U in a right eye and B.D in a
left eye until a horizontal line can
come to the center of a vertical line.
Right eye'sⓓ
hyperphoria
Add B.U in a left eye and B.D prism
in a right eye until a horizontal line
can come to the center of a vertical
line.
Phoria test (Fixation point of
cross phoria)
The test is for
measuring
vertical/horizontal
fixation disparity of
right or left eye by
using Red/Green
filter.
1. Show cross phoria test type to a patient.
2. Let a patient wear Red/Green glasses (right eye = red filter, left
eye = green filter). The patient sees « » mark in a right and «
» mark in a left eye on cross phoria test type. The binocular
condition would be ideal, if the patient could see « » mark.
3. Judge a patient's binocular function as below, while asking him
how the type is seen.
