(7) QS display area
The results of reliability (Quality Statement) of corneal
analysis are displayed. Click the button to switch the
display of detailed data ON and OFF. In the case of “QS:
NG," details are displayed automatically.
<RING> <SLIT>
Analyzed Area : Ratio of area of the mire ring
image that can be analyzed [%].
An error occurs when this value is
less than 80%.
Ratio of area of the slit image in the
Ø6 range that can be analyzed [%].
An error occurs when this value is
less than 90%.
If an error occurs, take the measurement again, making sure that the
cornea is sufficiently exposed such as by having the patient open their eye
wider.
Offset : Misalignment of the center of the
scan and corneal vertex [mm].
An error occurs when this value
exceeds 0.2 mm.
Misalignment of the center of the
scan and corneal vertex [mm].
An error occurs when this value
exceeds 0.6 mm.
If an error occurs, conduct alignment and take the measurement again.
Offset (Z) : Misalignment of the center of the
scan and corneal vertex in the
depth direction [mm].
An error occurs when this value
exceeds 0.15mm.
Misalignment of the center of the
scan and corneal vertex in the depth
direction [mm].
An error occurs when this value
exceeds 0.6 mm.
If an error occurs, conduct alignment and take the measurement again.
(8) <Keratometry> quantitative index display area
Displays the quantitative index of the basic information
of the corneal shape.
<IOL Choice> quantitative index display area
Displays the quantitative index of the basic information
of IOL selection.
● CEI:
Displays the corneal eccentricity.
Positive values represent a prolate shape where the
peripheral area is flat. "0" indicates a sphere and
negative values represent an oblate shape where
the peripheral area is steep.
