An extended focus,
a clean image.
The extended-depth-of-focus lens: distance and intermediate vision without glasses, with minimal light phenomena.
An EDOF IOL replaces the natural lens during cataract surgery or refractive lens exchange, extending focus across a continuous range from distance to intermediate vision. At Palazzo Manzoni in Brescia, the choice of lens begins with a complete diagnostic assessment, your lifestyle and an honest conversation about the trade-offs.

The starting point
You have been adapting for
a long time.
Perhaps the first thing you look for in the morning is your reading glasses. Perhaps you hold your arm out to read a label, or turn up the light to read a menu. Adapting has become such a quiet habit that you barely notice it.
Presbyopia and cataracts do not improve on their own: over time, the natural lens loses elasticity and transparency. Glasses compensate, but they do not restore freedom.
At Palazzo Manzoni in Brescia, the first step is simply a complete diagnostic assessment: understanding your eyes and your life before recommending any lens. About an hour, with no obligation.
What makes an EDOF IOL different
The difference is focus without gaps
Multifocal and trifocal lenses divide light between separate focal points: effective, but at the cost of possible night-time halos and a slight reduction in contrast.
An EDOF IOL takes a different path: it extends focus across a continuous range, from distance to intermediate vision, without jumps from one focal point to another. The result is an image closer to natural vision.
That brings three things: high contrast, more comfortable night driving and generally faster adaptation. Near vision remains its stated limitation: light glasses may be needed for small print.
01
Natural-lens contrast
The image remains clean, even in low light.
02
Night vision with fewer halos
Continuous focus markedly reduces light phenomena.
03
One department, one pathway
Diagnostics, implant and follow-ups, led by your specialist.

Is an EDOF IOL right for you?
Is an EDOF IOL
right for your eyes?
An EDOF IOL is not a universal lens: it is a precise answer for a precise profile, and the match matters. At Palazzo Manzoni, most EDOF candidates share some of these traits.
Clinical profile
- Developing cataract or advanced presbyopia
- Priority on image quality and night vision
- Healthy macula and retina
- No astigmatism, or astigmatism correctable with a toric version
- Realistic expectations for near vision: light glasses may be needed for small print
- No untreated active eye condition
Life profile
- Many hours of driving, including at night
- Sport and outdoor life, where contrast matters
- Days spent between screens, dashboards and intermediate distances
- Low tolerance for halos and compromises in image quality
- Comfortable using light glasses for prolonged reading
When an EDOF IOL is not the right answer
If your main goal is to read for long periods without any glasses, a trifocal or multifocal IOL provides better near vision. With significant macular disease, a monofocal IOL remains the more prudent choice.
If an EDOF IOL is right for you, the assessment will confirm it. If not, the right path will emerge from the same tests — and we will show it to you with the same clarity.
Evidence and technology
Decades of evidence,
on an advanced platform
Premium intraocular lenses rest on decades of clinical evidence: millions of implants documented in the literature, optical designs refined generation after generation and ever more precise selection criteria. Choosing the right lens is now a data-led decision, not a gamble.
At Palazzo Manzoni, the entire pathway — biometry, topography, lens calculation and implant — is carried out on the Zeiss platform, with the same specialist from diagnosis through the final check.
Day by day
The first 24 hours, the first week and the months that follow
The evening after surgery
Blurred or fluctuating vision is normal, as is a mild gritty sensation. You go home shortly after the implant with your eye-drop schedule in hand.
The next morning
Most patients already notice useful vision, which continues to clear over the following days. The first check confirms that everything is progressing as expected.
The first week
Vision refines and the image appears clean straight away: any light phenomena are mild. Continue the eye drops according to the plan provided.
The first month
Visual stability is reached for most patients. Distance and intermediate vision are now working together; near vision finds its balance, possibly with light glasses for prolonged reading.
3 to 6 months
The refractive result stabilises fully. A final check documents the outcome and completes the pathway — while we remain available for any questions.
Honest trade-offs
What an EDOF IOL
does not do
Every lens has its trade-offs, and being honest about them matters as much as surgical technique.
It does not restore the near vision of a twenty-year-old: for prolonged reading or small print, many patients use light glasses. And a mild night-time light effect, although uncommon, is not impossible.
As with any surgery, an implant is not risk-free: serious risks are uncommon and discussed individually during informed consent. Careful selection is the first safety measure.

Patient stories
They were where
you are now
Glasses have been part of your life for years, or reading has started to slip away. These stories tell of the step that changed things.
Real experiences from patients who took the step
I wore glasses for 18 years. I had not realised how much I had been adapting until I opened my eyes the morning after surgery and saw the ceiling clearly for the first time.
I had only come to resolve my cataract. The specialist explained the multifocal lens option, and now I see better than I did at 50. I have not touched my reading glasses since.
Two clinics had told me laser was not possible for my prescription. At Palazzo Manzoni, they suggested an ICL, and now I see perfectly. I wish I had known this option existed sooner.
Alternatives
If this lens is not the right one,
it does not end here
No lens is universal: every eye and every life call for a different design. If the assessment points to another path, we will show it with the same clarity.
A “no” to a specific design is never a dead end: it is the beginning of the right recommendation.
→Multifocal IOL
Two focal points, distance and near: when reading without glasses is the priority.
→Trifocal IOL
Three focal points, including the screen: maximum independence from glasses.
→Toric versions
Astigmatism correction, integrated into any design.
→Cataract surgery
When a cataract is the reason for surgery, opacity and lens are addressed together.
Your assessment will clarify which path is right.
Frequently asked questions
Frequently asked questions
about EDOF IOLs
What is an EDOF IOL?
It is an intraocular lens with extended depth of focus: instead of dividing light between several separate focal points, it extends focus across a continuous range from distance to intermediate vision. It replaces the natural lens during cataract surgery or refractive lens exchange.
How is it different from multifocal and trifocal IOLs?
Multifocal and trifocal IOLs create separate focal points; an EDOF IOL creates continuous focus. The result is an image with more contrast and fewer night-time light phenomena, at the cost of less powerful near vision.
Will I see well at night?
This is the EDOF IOL’s strength: halos and glare are markedly less frequent than with diffractive designs. A mild light effect remains possible in the first few weeks and is expected to ease.
Will I be able to read without glasses?
For short everyday reading — a phone, menu or prices — generally yes. For a book, small print or low light, light glasses are likely: this is the stated trade-off of this design.
What is mini-monovision?
It is a strategy in which the non-dominant eye is left slightly short-sighted: combining the two eyes broadens the focus range and improves near vision. It is tested before the final decision and adopted only if it feels comfortable.
I have astigmatism: can I have an EDOF IOL?
Yes, with the toric version, which corrects astigmatism in the same implant. Without correction, significant astigmatism would blur vision at every distance.
How long does the lens last?
For life: it does not wear out and does not need replacing. If the capsule behind the lens becomes cloudy over time, it can be resolved in a few minutes as an outpatient procedure with a YAG laser.
Is surgery painful?
No: the procedure uses eye drops only and takes around 10–15 minutes per eye, as day surgery. Mild discomfort or a gritty sensation in the first few hours is normal.
When can I return to my activities?
Useful vision returns in 24–48 hours; work and social life resume within a few days. Intense sports and swimming should wait a few weeks, according to your surgeon’s instructions.
How do I know if I am a candidate?
A complete diagnostic assessment tells us: biometry, corneal topography and retinal health. If an EDOF IOL is not the right lens, we will show you the alternative with the same clarity.
