    Extended depth-of-focus IOLs may provide improved visual performance

    Despite a variety of IOLs available, patients yearn for newer, advanced technologies

    As your patients celebrate another birthday milestone, they are again back in your chair wondering why their reading glasses mysteriously disappear when they are out exploring life or why their arms are not as long as they used to be. Do the above patient scenarios sound like déjà vu?

    Before you examine the validity of a conspiracy theory that every presbyope is against you, please understand that this dreaded discussion about presbyopic corrections is gut-wrenching for both doctors and patients. There may be a constellation of options available—glasses, contact lenses, or refractive surgeries—and yet each has its own associated compromises that your patients have to comprehend.

    Upon vaguely grasping the comparative concepts of monovision and multifocals, the potential visual compromises become more daunting when some treatment modalities appear not to be easily reversible, that is, surgery. Nonetheless, we are fortunate in that both our optical and surgical options continue to innovate and grow.

    With cataract surgery being one of the most common ophthalmic surgeries performed in the world—and the rising demand for a better quality of life from our patients­—the refractive benefits of a well-planned cataract surgery are immense. Patients often want to actively engage you in these presbyopic discussions. It is estimated that nearly 4 million cataract procedures are performed each year, and as the baby boomer population grows older, this number will only continue to trend upward.1

    Meeting patient’s IOL expectations

    Despite established monovision strategies with monofocal intraocular lenses (IOL) and a plethora of premium multifocal IOL options, patients continue to desire better functional outcomes that have a more continuous range of post-procedural vision. Patients also wish for less optical aberration-related limitations—most notably night haloes and glare. The latest IOL innovation is Tecnis Symfony and Tecnis Symfony Toric (Abbott Medical Optics), which will be available to U.S. patients in late 2016.

    Symfony and Symfony Toric represent a new category of premium IOL with a novel optical concept called extended depth of focus (EDOF), which may make our conversation more palatable for patients who want more visual freedom after surgery.
