Z CALC 2.2 Toric and Non-Toric IOL Calculation and Ordering

Z CALC:
Z CALC is a software intended to support a user in selecting intraocular lenses by calculation of intraocular lens power and predicted residual refraction. Z CALC can also be used for IOL power calculations for patients with previous LASIK, LASEK and PRK treatments.

The new Z CALC is compatible with the following browsers:
Microsoft Edge Version 18 or higher, Apple Safari Version 13 or higher, Mozilla Firefox Version 69.0 or higher (PC/ Mac), Google Chrome Version 76.0 or higher (PC/Mac), Internet Explorer Version 11, Google Chrome Mobile for Android Version 77.0 or higher and Apple Safari mobile 12.1 for iPhone/iPad Version 12.4 or higher.

3. Enter biometry examination date (optional).

4. Enter surgery date (optional).

Calculation Screen

5. Enter axial length from the patient’s record. Select IOLMaster for measurements with an optical biometry device or immersion ultrasound. Select applanation for measurements with applanation ultrasound.
6. Enter the ACD from the patient’s record and indicate if it has been measured from the epithelium or endothelium.
7. Please choose if you want to enter standard (K) Keratometry values or “Total Keratometry (TK)” values, if you want to use the TK values incorporating the posterior corneal curvature measurements from the IOLMaster 700.
8.Enter Flat Axis.
9. Enter the K- or TK-readings either in dpt or radii in mm.
10. Select the Refractive Index from the drop down menu.
11. Select Z CALC Nomogram*, if desired.
12. Insert target refraction, incision orientation and SIA for personalized calculation (optional).
13. Choose between toric or non-toric IOL calculation.
14. Select the desired IOL from the drop-down menu.
Click “Accept and calculate”.

Result Screen

A You may switch between “Standard Mode” or “Expanded Mode” by clicking the desired mode (top right corner).

• Standard Mode: Z CALC presents three calculations from which you may choose the most appropriate based on your requirements.

• Expanded Mode: You may vary Spherical Equivalent (SE) and cylinder powers (toric IOLs only) to review associated residual refraction and Effective Lens position (ELP).

• Mathematical compensation for the posterior corneal astigmatism (first implemented with v2.0).

IOL type selection

15. Choose between different IOL types from the dropdown menu from the generated readings.
16. Click on the “Add to wish list” button adjacent to the drop-down menu to transfer the result to the wish list.
