1.3 GLOSSARY

Following defines the meaning of the measure terms used

in this Manual.

A............................................. Astigmatism axial angle [ 0 to 180 degrees ]. Repressents the

angle of astigmatism at which the power is located in the

direction crossing the astigmatism axis.

A A ......................................... Auto Alignment ( see " Auto Alignment " ).

A S ......................................... Auto Shot ( see " Auto shot " ).

A V ......................................... Average ( mm ) of strong and weak principal meridians.

B C ......................................... Base Curve ( mm ).

C............................................. Cylinderical Power ( D ).

CAT ....................................... Cataract mode at the time of refractive measurement.

CEI ........................................ Corneal Eccentric Index.

CL .......................................... Contact Lens

D............................................. Diopter / Refractive power for near sight, far sight and

astigmatism.

FL .......................................... Framed Lens or Spectacles / When setting, calculation is made

with a VD or 12 mm or 13.5 mm.

K1 .......................................... Weak Principal Meridian ( mm or D ).

K2 .......................................... Strong Principal Meridians ( mm or D ).

N............................................. Measuring Number of Times ( times ).

PD .......................................... Interpupillary Distance

S ............................................. Spherical Power ( D ) / Represents the power of near sight or

far sight: with ( - ) for near sight and ( + ) for far sight.

TK1 ........................................ Approximate value of weak principal meridian calculated from

topography ( mm or D ).

TK2 ........................................ Approximate value of strong principal meridian calculated from

topography ( mm or D ).

1.3 GLOSSARY

8

VD .......................................... Corneal Apex Distance ( mm ) / Represents the distance between

the corneal apex and the lens to be prescribed. And the

spectacles become 12 mm or 13.5 mm when " VD = CL ",

calculation is made with VD of 0 mm, and the spectacles

become 12 mm or 13.5 mm. when " VD = CL " is displayed,

VD is calculated to be 0 mm.

Absolute Scale ...................... The scale by color distinction method was developed by

Professor Stepham D. K. of Louisiana State University

( LSU ). The scale between 90.0 and 100.0D is divided into 26

by allotting specific colors. This scale shows the identical

refraction power in the identical position for all the eyes

measured, which makes data comparison with other

measurement easy. The central part ( normal range ) of the

scale is divided with an interval of 1.50D having the standard

value ( 43.0D ) for normal eye at the center, which graduations

are colored with a bright green color. The upper and lower part

of the normal range is divided in an interval of 5.0D. The lower

part of the normal range gradually increases the blue color

darker as the upper part of the normal range gradually increases

the color brighter.

Auto Alignment .................... Misalignment of corneal center from the corneal image is

calculated for right / left, upper / lower, and front / rear to move

the measuring system to the amount of shifts. By using this

function, the examiner roughly adjusts the center of the cornea

with the joystick by watching the corneal images, which will

be followed by automatic alignment of the corneal center.

Automatic Fogging ............... Target is automatically moved to the far sighted side to provide

fogging, which eliminates Patient's eye adjustment.

Auto Shot .............................. Automatical measurement is performed while the corneal center

stays in the auto shot zone.

Corneal Curvature ............... Roundness of the cornea ( mm or D ).

Contact Lens List ................. The data of different contact lens models, which are taken by

measurement, are listed. The list is aimed at selection of the

first trial lens, while the prescription of the final contact lens

must be determined by fitting test.

1.3 GLOSSARY

9

and Error .............................. Refractive measurement may not correctly be made in the

following cases.

• In case the refractive power is not stable due to the

interference adjustment ( see " Adjustment " ).

• In case blinking is too frequent.

• In case the pupil s interfered with the eyelid or eyelash.

• In case the optic media of the patient eye is stained with

excessive turbid ( such as cataract and hemorrhage of eye

grand ).

• In case the measuring range of the equipment is exceeded.

Reliability coefficient of data is printed on the right end of

each measured value in a number of 0 to 9. Error

information is printed in two steps, depending on the degree

of error cause.

The mark of " e " is printed on the right side of measued

value, or which data reliability is inferior to that for ordinary

measurement.

Even in case of three consecutive measuring errors, " E "

mark is printed on the right side of measured values for

reference. Therefore, the reliability of data is inferior to that

for ordinary measurement.

Sleep Mode............................ In the Sleep Mode, the screen becomes dark with the power as

left ON, continuously illuminating the Power Lamp only. The

Sleep Mode functions in the Start Screen, the Measurement

Screen, and the Topography Map Display Screen, but does not

for the Setting Screen, which can be released by pressing the

MEASUREMENT BUTTON or changing the right/left with

the Joystick.

Adjustment ........................... Adjustment is made when focusing by swelling the lens to see

or peep a near object or when becoming tense.

Astigmatism Axis ................. The line connecting the points of the highest refractive values

and that connecting the points of the lowest refractive values

on the color map are displayed, which is not displayed if the

astigmatism is less than 1.0D.

Fixation Target ..................... Target guide Patient's fixation.

Reliability Coefficient

1.3 GLOSSARY

Display Instantaneous

10

Normalized Scale .................. Refractive values obtained from analytical results are

automatically distinguished with colors. This scale is graduated

with different colors for examining detailed configuration, of

which colors should cover only the range of refractive value

with which the measuring eye has as the results of analysis.

Sharp slope is displayed in a warm color, while a gentle

displayed in a cold color. Similar onfigurations are always

displayed in similar colors, unless absolute information of

refractive values is requested. In other word, corneas having a

similar configuration are displayed in similar colors in their

topography map. This scale is graduated into 11 parts with an

equal interval, and if the difference between the highest

refractive value and the lowest refractive value is large, while

if that between the two is smaller, the area of one color is less.

The minimum interval shall be 0.40D.

Base Curve ............................ Inner curve of the contact lens ( mm ).

Area Astigmatism ................ Strong meridian in the areas of 3 mm, 5 mm, and 7 mm from

the center of the cornea and refractive values ( mm or D ) and

axial angle on the strong and weak meridians are displayed. In

case the astigmatism is less than 10D, no display of such

information is displayed.

1.4 OUTLINE OF OPERATIONS

• Refractive power of an eye is examined by measuring the

infrared light reflected on the retina. Corneal topography and

curvature of the eye are also examined by measuring the

reflected light on the corneal surface.

• The patient places his chin on the Chin Rest and his / her

forhead on the Forehead Rest and next looks into the

fixation target. The Examiner focuses the bright spot for

centering the eye to be measured by observing on the

monitor. Adjust the bright spot up / down and left / right so

that it comes at the center of the screen. Auto-Alignment is

given by rough adjustment, in a similar manner to that

mentioned above and is given to assist the function used for

automatic alignment. After marking alignment, the examiner

presses the MEASUREMENT BUTTON to automatically

start measurement in the Auto Shot Mode. When

measurement start, the measuring light of infrared or visible

light is projected to analyze the refractive power and the

corneal configuration of the eye to be examined. Press the

PRINT BUTTON to print out measured data.

• The black colored display implies the misalignment within

the allowance range, which has no influence on the display

image.

• The yellow colored display implies the misalignment around

the allowance range, which may possibility have influence

on the display image.

• The red colored display implies the misalignment exclusive

of the allowance, which may have undue influence on the

display image and requires re-measurement.

• The ring pattern made in measurement is pro-jected after alignment is completed, for the rea-son of which a large extent of misalignment maypossibily be caused when the movement of thepatient is large. Such excesive misalignment can-not be revise, possibily causing a colored mapdifferent from the actual condition.

• The above topography shows an example Color Map for an

eye having no astigmatism, for which measurement was

taken with offsets and, therefore, the colors used for the Map

are symmetrically different between the right and left sides

from the center of the average value.
