13.12 IOL CALCULATION
ALADDIN also includes a section for calculation of the intraocular lenses (IOL Calculation).
In order to perform the intraocular lens power calculation, the available power interval, the increments and
the calculation constants must be provided for each type of formula and lens. These, however, do not depend
solely on the type of lens and the calculation formula, but are also closely linked to the measuring technology
and the surgical techniques used. It is strongly recommended that the user optimize the IOL constants in
clinical practice and the type of device used for acquisition of the biometric data.

The screen has various sections, which we will explore in detail below:
- Data
- IOL Calculation
- Toric IOL calculation
- Post Refractive IOL Calculation
Caution: The Toric IOL Calculation function is not available for the US market.
The first time a surgeon enters in IOL Calculation, it will appear the panel shown in Figure 47 that contains
the Disclaimer regarding the usage of the IOL Calculation. The Disclaimer will appear every time you enter
in IOL Calculation or you want to print a IOL report, unless you check the box below before clicking the OK
button. The Disclaimer is also replicated in the IOL settings (see 13.15.4.1), where you can even reactivate
its appearance at every IOL usage.
