    Customized IOL calculator helps cataract surgeons navigate lens choices

    Tool provides choice of computational strategies; ranking criteria selectable by each surgeon

    Champaign, IL—Cataract surgeons can use IOL calculators to help achieve the best possible surgical outcomes and spend less time calculating the right IOL choice, said Samir I. Sayegh, MD, PhD, FACS, The Eye Center, Champaign, IL.

    Some challenges that cataract surgeons face during the IOL selection process is calculating sphere, obtaining biometric data from multiple devices, and figuring out what other factors to include, such as multiple Ks, posterior astigmatism, and anterior chamber depth, Dr. Sayegh said.

    Yet other challenges that cataract surgeons grapple with include toric-related issues, such as using a fixed or variable “toricity ratio” and the sometimes-bewildering variety of IOLs and manufacturers.

    One tool that can help cataract surgeons is a universal, yet customized, IOL calculator, Dr. Sayegh said.

    Such a calculator would need to include several features, he explained.
