Basic software

Precise analysis. Clear presentation.

The comprehensive basic software contains various analysis for everyday use; from
topography to automatic keratoconus detection and an extensive contact lens database.

Overview and 3-D displays
The built-in Keratometer guarantees the utmost measuring
precision and reproducibility of the real Ks.The overview
display shows the keratometric values, the central radii, the
corneal astigmatism, the eccentricity and the corneal
diameter. The color topography map shows the curvature of
the anterior corneal surface.

Fourier analysis
The Fourier analysis is an important tool for visualizing the
amount of corneal irregularities. Using the Fourier analysis,
the topography map is divided into individual components.
The first three are standard components that represent
lower order aberration and the fourth map
shows the amount of corneal irregularities or higher order
aberration.

Zernike analysis
Zernike analysis provides a means to distinctly describe
irregularities of the cornea. If the indicated aberration
coefficient is elevated, it shows a decline of the optical
quality. The Zernike analysis enables the determination of
the exact position of the apex.

Indices
The Indices display helps with the quick and easy detection of
abnormalities in the topography. The measured values are
compared with a standard database.
If Keratoconus is present, it is detected at an early stage and
categorized according to the topography at hand. The indices
display is helpful during the follow-up examination and shows
whether the irregularities are changing or staying constant.
