    New EDOF IOL features novel optical design, reduced side effects, advanced chromatic optics

    A new extended depth of focus (EDOF) IOL provides excellent results for cataract surgery patients seeking presbyopia correction with good optical performance at the far and intermediate distance ranges and a low incidence of photic phenomena, said Florian T. Kretz, MD.

    “This novel EDOF IOL (AT LARA 829MP, Carl Zeiss Meditec) is the next-generation in EDOF IOL technology, featuring the widest range of focus within the EDOF segment,” said Dr. Kretz, CEO, owner of a private practice and clinic chain in Germany. “Based on our early clinical experience, we consider the AT LARA a useful option for individualizing patient care and a valuable addition for meeting the rising demands of today’s cataract surgery patients for good uncorrected intermediate vision.”

    The lens comes preloaded. It has received the CE Mark and was launched at the 2017 European Society of Cataract and Refractive Surgeons meeting. The lens is not yet approved in the United States.

    The name, LARA, reflects its “Light Bridge” optical design; Aspheric optics; Reduced visual side effects; and Advanced chromatic optics.

    “The AT LARA has a diffractive design with an optical bridge to continuously extend the range of focus,” said Steven C. Schallhorn, MD, chief medical officer, Carl Zeiss Meditec, Dublin, CA. “It features an optimized aberration-neutral aspheric design, and it incorporates patented design and manufacturing technology (Smooth Micro Phase) that reduces visual symptoms by minimizing light scattering. In addition, chromatic aberration has been optimized for increased contrast sensitivity.

    Dr. Schallhorn pointed out that the EDOF lens was designed to provide an excellent balance for patients wishing to reduce dependence on spectacles, while inducing less visual side effects than traditional multifocal IOLs.
