See your world more fully, from the road ahead to the screen in front of you with advanced lenses engineered to extend your natural range of vision.

Replacing Your Natural Lens to Improve Vision at All Distances

When cataract surgery is performed, your clouded natural lens is removed and replaced with an artificial intraocular lens (IOL). The lens you choose determines the quality and range of your vision for the rest of your life.

Standard monofocal lenses correct vision at one distance only — typically distance — leaving most patients dependent on reading glasses. Extended Range, also called Extended Depth of Focus (EDOF), lenses work differently. Rather than splitting incoming light into separate focal points, they extend it along a single, elongated focal zone. The result is crisp distance vision and strong intermediate sight — ideal for driving, screens, and most daily activities — with a natural visual quality that feels closer to how you saw before cataracts.

Why Patients Choose Extended Range Over Other Lens Options:

Compared to standard monofocal lenses, Extended Range lenses dramatically reduce dependence on glasses for everyday tasks. Compared to multifocal lenses, which divide light into three distinct focal zones, EDOF lenses produce fewer visual disturbances at night, including the halos and glare that some multifocal patients find difficult to adapt to. For active patients who drive frequently or spend significant time in front of screens, the difference is meaningful.

How Do They Work?

EDOF lenses use a graduated change in surface curvature, rather than distinct optical zones, to extend your depth of focus naturally. Where a multifocal lens essentially asks your brain to select from three focal points, an EDOF lens gives it a continuous range to work with, which most patients adapt to more quickly and comfortably.

What Is The Extended Range Lens?

Who Is A Good Candidate For Extended Range Lenses?

Why Choose Maloney-Shamie-Hura Vision Institute?

Our surgeons have performed thousands of advanced lens implant procedures and have deep expertise with the full range of Extended Range and premium IOL options. They take a highly individualized approach, your prescription, lifestyle, and visual priorities all factor into the recommendation. There is no one-size-fits-all lens, and you'll leave your consultation with a clear understanding of exactly why a specific option is right for you.

What Is the Difference Between Extended Range of Vision and Multifocal Lenses?

Multifocal lenses split incoming light into three distinct focal zones — distance, intermediate, and near. This can deliver excellent reading vision, but the light-splitting design causes some patients to experience halos and glare, particularly at night.
EDOF lenses use a single elongated focal point with a gradual shift in surface curvature, allowing the brain to transition across a continuous range of vision more naturally. Most patients adapt quickly, with significantly fewer nighttime visual disturbances.

The trade-off: EDOF lenses provide less near vision than multifocals, so some patients may still use reading glasses for fine print. For those who prioritize sharp distance and intermediate vision with minimal glare, EDOF is typically the stronger choice.

Vivity Extended Range Lenses

Dr. Shamie and Dr. Hura frequently recommend the Alcon Vivity lens, currently the most advanced EDOF lens available. Vivity uses proprietary X-WAVE technology, a non-diffractive design that stretches and shifts light rather than splitting it, producing a smooth, continuous range of vision without the optical trade-offs common to diffractive multifocal lenses. Vivity also includes built-in UV protection and blue light filtering — a meaningful benefit for patients who spend significant time on digital devices. For cataract patients seeking excellent distance and intermediate vision with minimal nighttime visual disturbance, Vivity is among the most compelling options available today.
