    How new ‘evolving’ IOL formula maximizes lens accuracy



    The Ladas Super Formula represents a novel step forward in the realm of IOL calculations. By leveraging 3-D mathematical modeling, we are able to understand modern IOL formulae like never before. By doing so, we also are able to take the best pieces of all formulae and amalgamate them together to create a single, ideal surface and consequently derive a formula (i.e., Ladas Super Formula).

    The key functionality of the Ladas Super Formula concept lies in its innate dynamism, which leaves room for development of optimization techniques. It is a “living” formula that is constantly evolving, and becomes more accurate as it progresses. By collaborating with a number of user groups and incorporating their actual patient data, we can adjust every grid box of the Ladas Super Surface and further enhance its accuracy.

    From this, we can obtain a Ladas Super Formula that will be more accurate than anything before it. The most appealing feature of this concept is that the Super Formula will never cease to improve.
