If cataracts are affecting your vision and you’re keen to reduce dependence on glasses, you may have come across Extended Depth of Focus (EDOF) lenses.
Patients from Market Harborough, Stamford, Peterborough, Oundle, Kettering and Northampton often ask:
“What exactly is an EDOF lens, and is it right for me?”
Below, we explain EDOF lenses in clear, reassuring terms to help you make an informed decision.
What is an EDOF lens?
An Extended Depth of Focus (EDOF) lens is a type of advanced intraocular lens (IOL) used during cataract surgery.
Unlike standard lenses that focus at a single distance, an EDOF lens is designed to:
- Provide clear distance vision
- Improve intermediate vision (computer screens, dashboards, cooking)
- Offer a smooth range of vision rather than multiple fixed focal points
The goal is good functional vision for most daily activities, with fewer visual disturbances.
How is an EDOF lens different from a standard lens?
A standard monofocal lens:
- Focuses at one distance only (usually far)
- Almost always requires glasses for reading and intermediate tasks
An EDOF lens:
- Extends the range of clear vision
- Reduces reliance on glasses for everyday tasks
- Offers a more natural visual experience
Many active adults prefer EDOF lenses for their balance of clarity and comfort.
How is an EDOF lens different from a multifocal lens?
This is a very common question.
Multifocal lenses:
- Provide near, intermediate and distance vision
- Can cause glare or halos, especially at night
EDOF lenses:
- Focus on distance and intermediate vision
- Have lower risk of glare and halos
- Provide more consistent visual quality
For many patients, EDOF lenses offer a middle ground between monofocal and multifocal lenses.
Who should consider an EDOF lens?
You may be a good candidate for an EDOF lens if you:
- Have cataracts
- Want to reduce dependence on glasses
- Drive regularly, including at night
- Use computers, tablets, or smartphones
- Enjoy hobbies like cooking, walking, golf, or travelling
Patients in Peterborough, Stamford and Market Harborough often choose EDOF lenses to stay active and independent.
Will I still need glasses with an EDOF lens?
Most patients find they:
- Do not need glasses for distance
- Rarely need glasses for intermediate tasks
- May need reading glasses for small print
This suits many people who want freedom for most of the day but are happy using light readers occasionally.
Are EDOF lenses safe?
Yes. EDOF lenses are clinically proven and widely used worldwide.
At Jesse Panthagani Eye Clinic, we use advanced eye measurements and careful planning to ensure:
- Accurate lens selection
- Precise placement
- Predictable, stable outcomes
Does everyone qualify for an EDOF lens?
Not everyone is suitable. We assess:
- Overall eye health
- Amount of astigmatism
- Retinal or corneal conditions
- Your visual expectations and lifestyle goals
A detailed consultation is essential to decide whether an EDOF lens is right for you.
How much does an EDOF lens cost?
EDOF lenses sit in our premium tier, at £4,400 per eye — or £4,700 per eye if you also need astigmatism correction (a premium toric lens). 10-month interest-free finance is available.
| Lens type | Price per eye |
|---|---|
| Monofocal | £4,000 |
| Monofocal toric | £4,200 |
| Premium (EDOF or multifocal) | £4,400 |
| Premium toric | £4,700 |
The price includes your pre-operative assessment and measurements, the lens, the procedure and all aftercare. See the full price list , or model your own situation with the cost calculator .
How does an EDOF lens compare with the alternatives?
| Monofocal | EDOF | Multifocal | |
|---|---|---|---|
| Distance vision | Excellent | Excellent | Excellent |
| Intermediate (screens, dashboard) | Glasses needed | Very good | Very good |
| Near (small print) | Glasses needed | Reading glasses often needed | Usually glasses-free |
| Night-time glare and haloes | Least | Low | Most likely |
| Price per eye | £4,000 | £4,400 | £4,400 |
EDOF is the middle path: a continuous range of focus with fewer night-vision compromises than a full multifocal, at the cost of still wanting reading glasses for the smallest print. See multifocal vs monofocal and monovision vs multifocal for the other comparisons.
What is night vision like with an EDOF lens?
This is the question that matters most to drivers. All lenses that extend the range of focus split light to some degree, and that can produce haloes or starbursts around headlights at night.
EDOF designs generally produce fewer and milder night-vision effects than full multifocal lenses, which is precisely why they suit people who drive a lot in the dark. Most patients who do notice haloes find they fade over the first few months as the brain adapts. We cover this in detail in glare and haloes at night .
If you drive professionally, say so at your consultation — it genuinely changes the recommendation.
How long does it take to adapt to an EDOF lens?
Vision is usually clear within days, but the brain continues to fine-tune for six to eight weeks. Reading fluency and night comfort typically improve across that period. The recovery timeline sets out what is normal at each stage.
