Biometry, IOL power formulae improve outcomes

Accuracy of IOL power calculation can be significantly increased through the use of a low-coherence laser interferometry device (Lenstar LS900, Haag-Streit) for optical biometry combined with a last-generation, four-variable, "paraxial" ray-tracing formula (Olsen formula; PhacoOptics software, IOL Innovations). The benefit is due to improved prediction of postoperative IOL position, said Thomas Olsen, MD.
