13 OPERATING INSTRUCTIONS
ALADDIN is designed to work in stand-alone mode. For this reason, all the software functions are
automatically loaded when the device is turned on, enabling the user to control the device and guiding him
or her through the various phases:
- Entry of patient data
- Acquisition of the various possible modes
- Display of measurements
- Selection of intraocular lenses
More information for each function and the description of all the settings and other functions included is
provided in the following paragraphs of this chapter, to which we refer you for further details.
To interact with the software, the LCD display with touchscreen is used. To activate the button or the desired
function, simply touch the screen close to the command. The screen is highly sensitive. Minimum pressure is
required, indeed advised.
13.1 General description of functionalities
The Aladdin device has the following functionalities:
 Cornea image acquisition and topographic analysis.
 Measurement of the eye's axial length.
 Measurement of the anterior chamber depth with the slit projection method.
 White-to-White measurement.
 Dynamic pupillometry acquisition: recording of a sequence of images of the pupil in varying light
conditions. Acquisition of the static pupillometry in controlled light conditions (photopic and
mesopic).
 Analysis of the wavefront aberrations generated by the front surface of the cornea with Zernike
analysis: information on the cornea's optical properties and on the optical problems that can hinder
vision.
 Intraocular lenses (IOL and Toric IOL) calculation, both BEFORE and AFTER refractive surgery (by
means of the Camellin-Calossi and Shammas No History formulae).
Refer to the literature related to the Camellin-Calossi formula (in case of specific questions please contact
