PUPILLOMETRY - It is performed with image analysis of the sequence of acquisition. The acquisition is

performed with LEDs of different wavelengths. The device uses infrared LEDs to dilate the pupil and white

LEDs to reproduce photopic light conditions and to contract the pupil. There are three modes:

 DYNAMIC Pupillometry acquisition in dynamic controlled light condition: mesopic  photopic 

mesopic.

 PHOTOPIC Pupillometry acquisition in static photopic controlled light conditions.

 MESOPIC Pupillometry acquisition in static mesopic controlled light conditions.

IOL CALCULATION - Intraocular lens power calculation and suggestion made using the following formulae:

Holladay 1, Haigis, Hoffer Q, SRK / T, SRK II, Camellin-Calossi, Shammas No history, Barrett Universal II. There

are three modes:

 IOL calculation: Calculating the total spherical power for an intraocular lens to be implanted.

 Toric IOL calculation: Calculating the spherical equivalent power, cylinder power and placement axis

for a toric intraocular lens to be implanted.

 Post refractive IOL calculation: Calculating intraocular lenses for patients who have undergone

refractive surgery to correct myopia or hypermetropia.

The ALADDIN HW3.0 has an onboard PC with a dedicated software providing all the functionalities described

above.

Please refer to the literature references listed in 19. Appendix: bibliography.

1.5 Essential Performance

 Keratometry (KER) Measurement

 Axial Length (AL) Measurement

 Anterior Chamber Depth (ACD), Central Corneal Thickness (CCT), Lens Thickness (LT) Measurement

1.6 Interaction with the patient

Patients do not control the device. They are positioned with their chin on the chinrest and their forehead

on the forehead-rest and they are asked to stay perfectly still and look at the fixation point with one eye.

The device is entirely controlled by specialized personnel.

The parts in contact with the patients are the followings:

 ABS chinrest

 Teflon forehead rest
