How to achieve the most accurate correction for your astigmatic patients?
Our goal is to assist surgeons with the most precise and reliable IOL calculations in order to achieve the utmost satisfaction level of patients with
corneal astigmatism. The new calculation method helps physicians select the appropriate toric IOL model and as such improves toric outcomes in
astigmastic patients.
Clinical background
Standard keratometric and topography machines tend to yield inaccurate results in assessing the net corneal astigmatic power.
Astigmatism is present on the posterior corneal surface, which is independent in magnitude and meridian from the astigmatism of the anterior
surface. Residual postoperative astigmatism occurs often in eyes with toric IOL implantation.
Solution
The PhysIOL toric calculator model uses the new Abulafia-Koch regression Formula developed in order to compensate for the posterior corneal
astigmatism effect.

What do studies say?“The prediction of postoperative
astigmatic outcomes can be
optimized by adjusting the PhysIOL
toric IOL calculator with the Abulafia-
Koch regression Formula.”

A new regression formula for toric IOL
calculations, J Cataract Refract Surg 2016;
42:663–671.
What are the new features?
A redesigned interface, user-friendly, intuitive and mobile responsive, integrating following features:
1 Abulafia-Koch regression Formula, which reportedly theoretically accounts for posterior corneal astigmatism. 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. Calculation using the Standard K method is also
possible.
2 HELP-button at each bloc that will help you understand and fill in each parameter.
3 Predictive patient-specific effective lens position (ELP) which improves the preoperative refractive predictability.

ATR = against the rule; IOL = intraocular lens; PCRI = peripheral corneal relaxing incision; WTR = with the rule
*Especially if spectacles have more ATR
Double C-loop technology: optimal stability
Besides its postoperative rotational stability, the double C-loop platform offers easy maneuverability, both clockwise and counter-
clockwise, for accurate axis placement of the IOL.
What do studies say?“Double C-loop haptics design provides
excellent capsular bag stability associa-
ted with a low amount of PCO. ”
Reference:
O. Findl, MD: Capsular bag stability and
posterior capsule opacification, Eurotimes,
February 2017.
What do studies say?“An exceptional average rotation of
1.85° +/- 1.01° was observed between
1 day and 3 months with the double
C-loop IOL.”
Reference:
F. Poyales, MD, et al.: Stability of a novel intra-
ocular lens design: comparison of two trifocal
lenses, J Refract Surg. 2016;32(6):394-402.
What do studies say?“In eyes with toric IOL implantation, corneal astigmatism
prediction errors with devices that measure anterior corneal
astigmatism only were 0.5 to 0.6 D WTR in WTR eyes and 0.2 to
0.3 D WTR in ATR eyes, showing the effect of posterior corneal
astigmatism.”
