new physiol toric calculator

PhysIOL supports you with the most precise and reliable IOL calculations that will help you achieve the utmost satisfaction level of patients with corneal astigmatism.


New features:

  • Abulafia-Koch toric regression formula, which reportedly theoretically accounts for posterior corneal astigmatism (Read the publication here). This calculation method uses the standard keratometry measurements (anterior K values) and estimates the total corneal astigmatism based on the Abulafia-Koch regression formula to improve the prediction of postoperative astigmatic outcome. You still have the possibility to use the Standard K calculation method as with the previous version.


  • Predictive patient-specific effective lens position (ELP) which improves the preoperative refractive predictability.
  • A HELP-button explaining each parameter
  • Mobile-responsiveness: use the calculator any time, any where, on any device.
