Presbyopia surgery — reducing your dependence on glasses after 45
Presbyopia is not a disease: it is the natural aging of the eye's lens, which loses its elasticity and can no longer accommodate for reading. Everyone goes through it from around age 45. There are two main families of surgical solutions to free yourself from it: laser corneal surgery (PresbyLASIK, laser monovision) — the reference option for patients under 55 whose lens is still clear — and lens surgery, in which the natural lens is replaced with an intraocular lens (EDOF, multifocal). The right choice depends on your age, the condition of your lens and your lifestyle.
What is presbyopia?
Presbyopia is not a disease: it is a natural, universal phenomenon caused by the lens losing its elasticity with age. It is sometimes confused with early cataract — my article “Cataract or presbyopia: what's the difference?” will help you tell the two apart.
How it works
The crystalline lens is your eye's natural lens. When you look into the distance, it is flat. When you look at something close up, tiny muscles (the ciliary body) make it rounder — this is called accommodation. This auto-focus ability is essential for comfortable reading.
With age, the fibers of the lens gradually stiffen and it loses its ability to change shape. Around age 45, the amplitude of accommodation becomes insufficient for comfortable reading at 30–40 cm. This is presbyopia. It progresses gradually until about age 55–60, then stabilizes (the reading addition you need stops increasing).
Symptoms
- Eye strain at the end of the day, especially after prolonged reading
- Needing to hold text further away to see it clearly (“arms too short” syndrome)
- Difficulty with small print, labels, smartphones
- Needing more light to read
- Headaches at the end of the day
- Blurred near vision that improves when you move the object further away
Presbyopia ≠ cataract
Presbyopia and cataract both affect the lens, but they are two different phenomena:
- Presbyopia = a functional disorder (loss of accommodation). The lens remains clear. Appears around age 45.
- Cataract = clouding of the lens. Appears later, around age 60–70.
This distinction is crucial when choosing a surgical strategy. As long as the lens is clear, laser corneal surgery (PresbyLASIK) is generally the most suitable solution. Once the lens starts to become cloudy, lens surgery becomes the approach of choice.
Good to know: there is no medical treatment (eye drops, vitamins, exercises) that reverses presbyopia. The only solutions are glasses, contact lenses or surgery. Learn more about how presbyopia develops →
Why reading becomes difficult
When you were young, your lens could quickly become rounder to focus on a nearby object — like a camera's auto-focus. This is accommodation, triggered by the ciliary muscles.
With age, the lens fibers lose their flexibility. By age 45, the amplitude of accommodation is roughly halved; by 55–60, only a residual amount remains. The optical focus stays fixed on distance vision, and near images can no longer be brought into sharp focus on the retina. This is what makes reading blurry.
The goal of presbyopia surgery is to restore clear near vision without glasses, either by reshaping the cornea to create multifocality (PresbyLASIK), or by replacing the lens with an intraocular lens that creates several foci (EDOF, multifocal).
Two main families of solutions
The choice depends first and foremost on the condition of your lens. If it is still clear (typically before age 55), laser corneal surgery is the reference approach. If it is starting to become cloudy, or if presbyopia is very advanced, lens surgery becomes more appropriate.
The treatment is applied to the cornea; the lens is left untouched. The reference solution for patients under 55 whose lens is still perfectly clear.
- PresbyLASIK — multifocal corneal profile (LASIK adapted for presbyopia)
- Laser monovision — one eye corrected for distance, the other slightly offset for near
- Fast recovery: 24 to 72 hours
- Adjustable with an enhancement (LASIK), natural lens preserved
- Prior contact lens trial required
The natural lens is replaced with an intraocular lens that restores vision at several distances. The solution of choice for patients over 55 or when the lens is starting to become cloudy.
- EDOF IOL — extended vision from distance to intermediate
- Multifocal / trifocal IOL — vision at all distances
- Permanent — avoids future cataract surgery
- Available in a toric version (astigmatism correction)
- Visual recovery from the next day
Laser corneal surgery — the reference solution before age 55
The laser reshapes the cornea to create multifocality or to slightly offset the correction between the two eyes. The natural lens remains intact — the main advantage of this approach while the lens is still clear: you avoid intraocular surgery that may be needed later for a cataract anyway.
A variant of LASIK specifically adapted for presbyopia. I reshape your cornea according to a multifocal aspheric profile: the center is dedicated to near vision and the periphery to distance vision (or vice versa). The brain learns to use the most appropriate optical zone depending on the viewing distance. The reference solution for correcting distance and near vision at the same time.
- Distance and near vision, in most cases without correction
- Ideal profile: age 45–55, clear lens
- Recovery in 24 to 48 hours, neuroadaptation over 1 to 3 months
- Micro-monovision variant possible (slight residual myopia in the non-dominant eye)
- Contact lens trial required before surgery
- Particularly suitable for hyperopic patients with presbyopia
A simpler approach than PresbyLASIK: I correct the dominant eye for distance vision and leave the other eye slightly myopic for near vision. The brain naturally switches between the two depending on the distance. No complex multifocal profile — just an offset in correction. A proven solution, particularly well suited to myopic patients with early presbyopia.
- Simple technique — LASIK or SMILE
- Fast recovery (24 to 72 hours)
- Brain adaptation in 2 to 4 weeks
- Tolerance to be tested before surgery (contact lens trial)
- Indicated for patients aged 45–55 with mild myopia + presbyopia
- A distance / near vision trade-off to accept (reduced stereoscopic vision)
Why favor the corneal option whenever possible? As long as your lens is clear, corneal surgery preserves it and remains adjustable with a secondary enhancement. When a cataract eventually develops (around age 65–70), we can still operate and choose a suitable intraocular lens. Conversely, replacing a clear lens with an IOL is a permanent and more invasive procedure.
Lens surgery — the intraocular lens
I replace your natural lens (still clear or with early cataract) with a premium intraocular lens that creates several focal points. A permanent solution: the IOL stays in place for life, and a cataract can never develop afterwards. Mainly indicated for patients over 55, or earlier in case of a significant refractive error associated with presbyopia.
I replace your natural lens — still clear, with no cataract — with an EDOF (Extended Depth of Focus) intraocular lens. This technique provides clear vision at distance and intermediate range (computer screen, car dashboard), with excellent preserved optical quality and few halos at night. Occasional glasses for fine print.
- Extended vision at distance + intermediate (50 to 80 cm)
- Mild halos at night, usually well tolerated
- Permanent — you will avoid future cataract surgery
- Available in a toric version (astigmatism)
- Suitable for demanding patients (preserved optical quality)
- An excellent alternative when PresbyLASIK is no longer indicated
The same technique as clear lens exchange with EDOF, but using a multifocal or trifocal IOL with diffractive optics. You see clearly at all distances — far, intermediate and near — including reading without glasses. High independence from glasses, at the cost of more noticeable halos at night and a longer neuroadaptation period.
- Broad independence from glasses (distance + intermediate + near)
- Reading usually possible without correction
- Suitable for sports requiring vision at multiple distances
- Available in a toric version
- More noticeable halos at night — to be considered if you drive frequently at night
- Neuroadaptation over 3 to 6 months

Which technique for which profile?
These are the most common matches in practice. They should always be confirmed by a personalized assessment.
This is the ideal indication for PresbyLASIK. Your lens is still fully functional, and corneal laser treatment restores multifocal vision without operating inside the eye. The procedure is quick (15 minutes for both eyes), minimally invasive, and preserves your natural lens for decades to come. A cataract can be operated on later if needed — PresbyLASIK poses no problem for that future procedure. See the PresbyLASIK page →
If you are slightly myopic and your presbyopia is just beginning, conventional laser monovision (LASIK or SMILE) is a simple and effective solution: one eye is corrected for distance, the other left slightly myopic for near vision. PresbyLASIK also remains an option if you want more complete multifocality in both eyes. The contact lens trial helps decide.
If your presbyopia is well established and PresbyLASIK is no longer optimal (lens starting to lose clarity, advanced presbyopia), replacing the lens with an EDOF IOL is the solution. Clear vision at distance and intermediate range, preserved optical quality, mild halos at night. At the same time, you avoid future cataract surgery.
If your priority is maximum independence from glasses — including for reading a book, a smartphone or a label — and your eye profile is compatible (regular cornea, suitable pupils, limited night driving), a multifocal or trifocal IOL is indicated. Halos at night must be accepted, with neuroadaptation over 3 to 6 months.
If your lens is starting to become cloudy, cataract surgery becomes the ideal indication — it treats presbyopia and the developing cataract at the same time. The choice between monofocal, EDOF, multifocal or trifocal depends on your expectations. See the cataract page →
If you are highly hyperopic (above +3 D) and presbyopic, PresbyLASIK is a particularly well-suited indication of choice. For highly myopic patients (beyond −6 D) with presbyopia, clear lens exchange may be preferred, as the lens often starts to become cloudy earlier in high myopes. EDOF or multifocal IOL depending on your lifestyle.
If you drive frequently at night (chauffeur, ambulance driver, long professional journeys), I will rather steer you towards laser monovision or an EDOF IOL — which best preserve optical quality at night. Multifocal PresbyLASIK and multifocal IOLs are best reserved for occasional night drivers to avoid discomfort from halos.
Am I a candidate?
- You are over 45
- Your presbyopia is established and bothers you in daily life
- Your prescription has been stable for at least 1 year
- Your cornea is regular (topography without irregularity)
- Your retina is healthy (normal macular OCT)
- Your expectations are realistic — you understand the trade-offs
- You are willing to do a contact lens trial if PresbyLASIK or monovision is considered
- Associated retinal disease (AMD, ERM) — restricted choice of IOL
- Glaucoma with advanced visual field damage
- Irregular cornea (keratoconus, at-risk history of LASIK)
- Severe, uncontrolled dry eye disease
- Highly demanding occupation with intensive night driving
- Very anxious personality / low tolerance for trade-offs
- Unrealistic expectations (“I want perfect vision like when I was 20”)
None of these situations is an absolute contraindication: we adapt the strategy together (for example, an aspheric monofocal IOL + reading glasses if multifocality is not indicated).
Advantages and points to consider
- Freedom from reading glasses and progressive lenses
- Natural vision restored at several distances
- Solutions adaptable to your lifestyle (cornea or lens)
- With clear lens exchange (PRELEX): prevention of future cataract
- With PresbyLASIK: recovery in 24–48 hours, minimally invasive, natural lens preserved
- Possible simultaneous correction of myopia / hyperopia / astigmatism
- Possible halos at night (moderate with PresbyLASIK / multifocal, mild with EDOF)
- Neuroadaptation required (2 weeks to 6 months depending on the technique)
- Contact lens trial required before PresbyLASIK or monovision
- Premium IOLs and clear lens surgery are not covered by French national health insurance
- A compatible profile is required (cornea, pupils, expectations)
- An intraocular lens is permanent — careful consideration beforehand is important
Specific risks of PRELEX (clear lens exchange)
PRELEX is elective intraocular surgery. The risks are the same as those of standard cataract surgery, but must be weighed differently since the lens is still clear:
- Retinal detachment — a modest but real risk, higher in axial myopia (beyond −6 D)
- Postoperative endophthalmitis — about 0.02 to 0.05% per operated eye (1 in 2,000 to 1 in 5,000) with intracameral antibiotic prophylaxis
- Cystoid macular edema (Irvine-Gass syndrome) — 1 to 2%
- Residual refractive error requiring a secondary enhancement — 5 to 10%
- Posterior capsule opacification (“secondary cataract”) — 20 to 30% at 5 years, simply treated with YAG laser (see dedicated page)
These risks are weighed against the expected benefit and explained in detail during the pre-operative assessment. The decision is shared.

From assessment to visual freedom
Comprehensive assessment
Precise refraction, biometry, corneal topography (Anterion), macular OCT, evaluation of the lens (clarity, density). In-depth discussion of your needs, visual habits and expectations.
Choosing the family
Depending on the condition of your lens and your age, I will steer you towards laser corneal surgery (PresbyLASIK / monovision) or lens surgery (EDOF / multifocal IOL). I present the compatible options with their advantages and limitations.
Contact lens trial (if laser)
For PresbyLASIK and monovision, a contact lens trial over a few days lets you judge your tolerance in real-life conditions before surgery. This is a key step in maximizing your chances of post-operative satisfaction.
Surgery & follow-up
Corneal laser: 15 minutes for both eyes, outpatient. Lens surgery: ~10 minutes per eye, second eye operated 1 to 2 weeks later. Check-ups at day 1, day 7 and 1 month. Neuroadaptation over 2 weeks (monovision) to 6 months (multifocal).
