11.9 Acquisition of the anterior segment sections (CCT-ACD-LT)
The AL measurement must be performed before CCT-ACD-LT measurement in order to have a LT
result without warning.
A standalone CCT-ACD-LT measurement cannot be perform without a valid AL result.
With this type of acquisition measurements about the sections of the anterior segment of the eye are taken
using the interferometer system.
By selecting this mode, the acquisition environment appears as shown in Figure 34.
Press the joystick button and move the device according to the instructions of the automatic guidance system
(red/blue arrows and centering aims) until ideal conditions have been reached (green icons and centered
aims).

11.10 Keratometry acquisition (KER)
Keratometry is used to measure the corneal curvature. It is based on the reflection of the Placido disk on the
eye at a controlled working distance for high measurement precision.
ALADDIN HW3.0 allows the user to acquire the corneal topography of the eye. The “Corneal Map” is obtained
from the reflection of 24 rings of the Placido disk at a distance of 80 millimeters from the patient's eye. The
position of the device, in relation to the patient’s eye thus found, serves as a starting point for fine
adjustments to be made in the respective measurement mode.
By selecting this mode, the acquisition environment shown in Figure 35 appears.
