EDOF lens (extended depth of focus)
An EDOF lens stretches your clear range so that distance and computer-range vision are usually good without glasses.
What to expect
An EDOF lens creates one continuous stretched range of clear vision, rather than separate focal points for near and far. The aim is a smooth band of focus rather than distinct zones.
This usually covers distance vision and what is often called computer range — roughly the distance of your outstretched arm, a car dashboard, a laptop screen, or a price tag on a shelf.
Fine print often still needs reading glasses. A medicine label or a phone screen in dim light are common examples where close-up vision may not be clear enough without glasses.
What it does well
- Strong distance and computer-range vision
- Less dependence on glasses than a standard monofocal
- Generally fewer halos and glare than a full-range trifocal
Trade-offs to discuss with your surgeon
- Reading glasses may still be needed for fine print
- Provides less near range than a full-range trifocal
Using both eyes together
An EDOF lens is sometimes used as part of a blended vision approach.
Blended vision uses the two eyes together, with one eye generally optimized more for distance and the other contributing more intermediate or near vision. It may be worth discussing, particularly if you have successfully used monovision before. Your surgeon will determine whether it is appropriate.
Questions to ask your surgeon
- What would I still need glasses for day to day?
- How is this different from a trifocal for my eyes?
- Do I have any night-driving concerns that affect this choice?
- Do my measurements show astigmatism, and would you use a toric version?

About astigmatism
If your measurements show meaningful astigmatism, your surgeon may recommend a toric version of the selected lens category.
Your surgeon may also discuss laser-assisted cataract surgery. The laser can help perform certain steps with added precision, soften the cataract before removal, and treat small amounts of astigmatism. It is commonly included with advanced lens packages at participating practices.
Some advanced lens and laser options involve costs that are not covered by insurance. Exact pricing depends on the option selected and will be explained by your surgical scheduler.
This educational tool does not diagnose eye conditions, determine whether you are a candidate for a specific lens, or replace a discussion with your surgeon. Your surgeon will recommend appropriate options after examining your eyes.
