Understand Your IOL Options Before Making a Lifelong Decision
Cataract surgery can restore your vision — but different artificial lenses create different visual experiences. Learn how IOL options may affect reading, computer work, driving, night vision and dependence on glasses before discussing your final choice with your surgeon.
Where should I start?
I have cataract
Understand what cataract is, when surgery may be considered and what happens next.
I need to choose an IOL
Understand the main lens categories, their benefits and their trade-offs.
I was offered a specific IOL
Research the technology, expected visual range, limitations and alternatives.
I don't know what vision I need
Explore your visual priorities and daily activities before comparing lens options.

Start with your everyday vision
Compare the options Four lens types. What changes in daily life?
Reading a book, working at a screen, looking down the street: the same three tasks help explain the differences between lenses.

ComputerIntermediate · around 60–100 cm
DistanceFar · around 2 m and beyond
The comparison below assumes the lenses are chosen with distance vision in mind.
Monofocal
ExploreNearUsually need glasses
ScreenGlasses may be needed
FarUsually without glasses
With the main focus set for distance, near reading usually needs glasses. A screen may also need a separate prescription.
Enhanced monofocal
ExploreNearUsually need glasses
ScreenMore often without glasses*
FarUsually without glasses
*More often than with a standard monofocal. How much this helps depends on the particular lens and screen distance. Near reading still usually needs glasses.
EDOF

Distance and computer work are the main strengths. Fine print and sustained near reading often still need glasses.

Designed to reduce reliance on glasses from distance to near. Small print or poor light can still make glasses useful.
This shows what each lens type aims to do, not a score or a prediction of your vision. Glasses may still be useful with any type. A monofocal can also be set for a nearer distance; choosing a different focus in each eye changes the picture. More about choosing the focus →
