Multifocal vs Extended Depth of Focus Lenses
Understanding the differences between these advanced intraocular lens options will help you make the best choice for your vision needs.
Overview
Both multifocal and extended depth of focus (EDOF) lenses are premium intraocular lens options designed to reduce your dependence on glasses after cataract surgery. While they share the common goal of providing vision at multiple distances, they achieve this in different ways and offer distinct advantages.
See the Difference
This image compares the visual experience between a multifocal lens (PanOptix® Pro IOL, shown on the left) and an extended depth of focus lens (Vivity® IOL, shown on the right). Notice how the multifocal lens provides significantly sharper near vision—you can clearly read the text on the laptop screen and see fine details up close. This enhanced near vision capability means many patients can read books, menus, and phones without needing reading glasses at all.
The EDOF lens, while offering excellent distance and intermediate vision with fewer visual side effects like halos, may require reading glasses for prolonged close-up tasks or very small print.

Key Differences
Multifocal Lenses
How They Work
Multifocal lenses have multiple focal points built into the lens design. They split incoming light into different zones, with each zone dedicated to a specific distance (near, intermediate, or far).
Advantages
- • Excellent near vision for reading and close work
- • Clear distance vision for driving and daily activities
- • Multiple distinct focal points
- • High patient satisfaction for reading
Considerations
- • May experience halos or glare around lights, especially at night
- • Some patients notice reduced contrast sensitivity
- • Brain adaptation period may be needed
Extended Depth of Focus (EDOF) Lenses
How They Work
EDOF lenses create a continuous, elongated focal point rather than multiple distinct zones. This provides a seamless range of vision from distance through intermediate, with less light splitting.
Advantages
- • Excellent distance and intermediate vision
- • Significantly reduced halos and glare compared to multifocal
- • Better contrast sensitivity
- • Smoother transition between distances
- • Easier adaptation period
Considerations
- • Near vision may not be as sharp as multifocal lenses
- • Reading glasses may still be needed for prolonged close work
- • Better suited for computer work and dashboard viewing
Night Driving: Glare & Halos Comparison
Mild Glare Conditions
Major Glare Conditions
These images simulate the difference in nighttime driving experience between a multifocal lens (PanOptix® Pro IOL, shown on the left of each image) and an extended depth of focus lens (Vivity® IOL, shown on the right). The first image demonstrates mild glare conditions, while the second image shows more significant glare.
Notice how the multifocal lens produces more pronounced halos and glare around headlights and streetlights compared to the EDOF lens. This increased light scatter is a natural result of the multifocal lens design, which splits light into multiple focal zones. For patients who frequently drive at night, these visual phenomena may make nighttime driving more challenging with a multifocal lens.
The EDOF lens, by contrast, produces significantly less glare and fewer halos, providing a clearer, more comfortable nighttime driving experience. This is an important consideration when choosing between these premium lens options.

Which Lens is Right for You?
Consider Multifocal Lenses If:
- • You want maximum independence from reading glasses
- • You frequently read books, newspapers, or do detailed close work
- • You're willing to accept some potential visual side effects
- • You want clear vision at all distances including very close
Consider EDOF Lenses If:
- • You drive frequently, especially at night
- • You spend significant time on computers or tablets
- • You prioritize visual quality and contrast
- • You're sensitive to glare or halos
- • You don't mind using readers occasionally for very small print
The Best Choice for You
The decision between multifocal and EDOF lenses is highly personal and depends on your lifestyle, visual needs, and expectations. During your consultation, we'll conduct a comprehensive evaluation and discuss your daily activities to help you choose the lens that best matches your unique requirements.
