One-Step Optimization

Three Variable method optimization, is a novel way of optimizing an entire dataset with just 3 variables:
-IOL Constant (either A constant, Hoffer pACD of SF)
-Mean PE (Actual refraction - Expected refraction) of the entire dataset
-Avg. IOL power of the whole dataset.

The intention is to calculate a new constant in order to reduce the PE at its minimum.

We are working in order to have a published paper explaining the details of the method, but this free online tool lets you use it beforehand.

It's simple, anonymous, and you don't need to gather all the biometric data of each patient and reach the formula author.

Just calculate the IOL power as usual, using your biometer or the ESCRS online IOL calculator, write down in a spreadsheet the expected seq of each formula and then perform a manual refraction at least 6 weeks after surgery, and start calculating the PE of each patient.
A PE of -0.75 corresponds to a hyperopic result. PE is Actual refraction - expected refraction, so if you do a calculation in order to obtain -0.75, and the post operative refraction was 0, then the PE corresponds to +0.75.

The idea is to encourage ophthalmologists who don't optimize their constants to do so in an easy way.
