screening result obtained from the anterior data.
● AA@6mm: Percentage of the area (range) that could
be analyzed within Φ6 mm on the anterior. If the value
of AA@6mm is small and the reliability of the anterior
data is low, “N/A” is shown for ESI in red.
Lower right section (Posterior)
● ESI: ESI (Ectasia Screening Index) indicates the
screening result obtained from the posterior data.
● AA@6mm: Percentage of the area (range) that could
be analyzed within Φ6 mm on the posterior. If the value
of AA@6mm is small and the reliability of the posterior
data is low, “N/A” is shown for ESI in red.
(2) Slit image
An image slit in the horizontal direction is displayed.
(3) Axial Power [Keratometric] map
The quantitative index is calculated by conducting
Fourier analysis for the axial power [Keratometric] data.
● Sph.@6:
Spherical component of Fourier analysis within the
range of Φ6 mm [D]
● Reg.@6:
Regular astigmatism component of Fourier analysis
within the range of Φ6 mm [D]
● Asy.@6:
Asymmetry component of Fourier analysis within the
range of Φ6 mm [D]
● Hio.@6:
Higher order irregular astigmatism component of
Fourier analysis within the range of Φ6 mm [D]
(4) Axial Power [Posterior] map
The quantitative index is calculated by conducting
Fourier analysis on the axial power [Posterior] data.
(Refer to “(3) Axial Power [Keratometric] map” for each
quantitative index.)
