## What is IOL Toric Calculator?

The TORIC CALCULATOR is an application that helps the surgeon to simulate the amount of corneal astigmatism to be corrected by selecting the recommended toric IOL power, and determining optimum IOL position axis in the capsular bag.


***** IF YOU ARE NOT A CATARACT SURGEON, PROBABLY WILL NOT BE INTERESTED IN THIS APPLICATION! *****

***** THIS APPLICATION IS FOR REFERENCE AND SIMULATION ONLY *****


Using the TORIC CALCULATOR:

To use it, just provide the requested patient data (some fields are optional) and press the CALCULATE button!

The application will perform the calculations to determine the crossed result astigmatism and suggest the Toric IOL to minimize the cylinder power.

An amazing feature allows you to modify the model of the Toric IOL, rotate it and change the location of the induced astigmatism to get better results with other lenses than suggested by the calculator.

You can share the results by email, print or save to camera roll.

## Key features

- Simulate corneal astigmatism correction
- Determine optimal toric IOL power
- Calculate optimum IOL position axis
- Minimize cylinder power
- Modify Toric IOL models
- Share results via email, print, or save

### 5/5 — Excellent

*2012-02-07*

Exactly what I was looking for. Allows one to change multiple parameters - toric power, axis, incision location - to help optimize outcomes. I expect it would be the best tool available to plan rotation of a malpositioned lens, though I have not needed to do that (yet). Highly recommend to anyone implanting toric lenses.

## Frequently asked questions about IOL Toric Calculator

### What is the IOL Toric Calculator used for?

The IOL Toric Calculator is a medical application designed to help surgeons simulate the amount of corneal astigmatism to be corrected when selecting a toric IOL. It assists in determining the optimal IOL power and axis position within the capsular bag to minimize cylinder power.

### Who is the IOL Toric Calculator intended for?
