Multifocal cataract implant: trifocal PanOptix, FineVision, Synergy
Doing away with glasses for good, at every distance, after your cataract surgery. Thanks to the diffractive rings etched onto the optic, the multifocal implant creates several simultaneous focal points: distance, intermediate and near vision. How it works, who is a candidate, trifocal models and expected outcomes.
The multifocal implant, and the trifocal implant in particular, represents the technological pinnacle of cataract surgery. Thanks to diffractive rings etched onto the surface of the optic, it creates several focal points simultaneously: distance vision (driving, television), intermediate vision (computer, dashboard) and near vision (reading, smartphone). The result: spectacle independence of 90 to 95% in international clinical studies.
Dr Moïse Tourabaly works with the three main trifocal implant references available in France, PanOptix (Alcon), FineVision (BVI/PhysIOL) and Synergy (Johnson & Johnson), after a personalized analysis of your eye and your lifestyle.
How does a multifocal implant work?
A conventional monofocal implant has a single optical power: light converges on the retina for one distance only, usually distance vision. The multifocal implant intelligently distributes light across several focal points thanks to a microscopic diffractive relief on the optic.
- Bifocal implant: 2 focal points (distance + near). An older range, gradually being replaced by trifocals.
- Trifocal implant: 3 focal points (distance + intermediate 60–80 cm + near 40 cm). Addresses the 3 distances of modern life.
- Synergy implant (extended EDOF + near focal point): a hybrid approach combining extended depth of field with a near focal point, particularly suited to astigmatic eyes and prolonged intermediate vision.
The 3 references used by Dr Tourabaly
PanOptix (Alcon)
The most widely implanted trifocal in the world. Designed with an intermediate focal point at 60 cm optimized for the desktop computer and the dashboard. Good tolerance of night-time halos thanks to its ENLIGHTEN technology (energy optimization). Available in a toric version for astigmatic patients. A first-line choice for active patients who use computer + smartphone + reading + driving.
FineVision (BVI/PhysIOL)
The first trifocal to appear on the European market (2010). Excellent near and intermediate vision. A slightly different energy profile from PanOptix; some patients prefer it for reading fine print. Available in a toric version (POD FT).
Synergy (Johnson & Johnson)
A hybrid approach: continuous depth of field from distance to intermediate (EDOF technology), supplemented by a near focal point. It offers one of the best intermediate-vision profiles on the market, at the cost of night-time halos that are sometimes more pronounced during the first months. Of interest to patients who spend a lot of time on screens.
Who is a good candidate for a multifocal implant?
The multifocal implant is not suitable for every eye. The preoperative assessment is decisive. Dr Tourabaly recommends a trifocal only when the following conditions are met:
- Healthy, regular cornea (Pentacam topography with no sign of keratoconus, no prior refractive surgery or otherwise compatible)
- Intact retina — no AMD, no diabetic maculopathy, normal macular OCT
- Healthy optic nerve — no progressive glaucoma
- Good-quality tear film — severe dry eye always degrades the performance of a multifocal
- Normal pupil size in scotopic conditions (5 to 6 mm); beyond this, halos can be bothersome
- A motivated, informed patient, accepting a neuro-adaptation period of 3 to 6 months
The trade-offs to be aware of
No implant is perfect. The trifocal has 3 limitations that are essential to know before choosing:
- Night-time halos and dysphotopsia: 100% of patients report them in the first 2 weeks, 30% still perceive them at 3 months, and fewer than 5% after 6 months. Cerebral neuro-adaptation gradually eliminates them.
- Slight reduction in contrast: distributing light across 3 focal points causes a loss of about 10% in contrast sensitivity. In practice, this is imperceptible under normal conditions and slightly noticeable in low light or in rain at night.
- The need for a flawless assessment: the slightest associated eye condition (dry eye, early maculopathy, irregular astigmatism) lowers satisfaction. Hence the importance of a thorough consultation.
Expected outcomes after trifocal implantation
| Distance | Vision expected without glasses |
|---|---|
| Distance vision (> 4 m) | 20/20 in 92% of patients operated on both eyes |
| Intermediate (60–80 cm, computer) | 20/20 in 88% |
| Near vision (30–40 cm, reading) | Parinaud 2 in 90% (reading a newspaper) |
| Complete independence from glasses | 90 to 95% of patients according to studies |
Price and reimbursement
The cataract surgical procedure itself (operating room, anesthesia, surgeon) is fully covered by the French social security system and supplementary health insurance. The multifocal/trifocal implant surcharge remains the patient’s responsibility: €900 to €1,400 per eye (€1,200 to €1,700 for the toric version).
A detailed quote is provided to you during the consultation, before any decision. Many premium supplementary insurance plans cover all or part of the surcharge; it is worth asking them once you receive the quote.
How the procedure unfolds
Surgery with a multifocal implant proceeds exactly like standard cataract surgery; only the implant placed at step 5 changes. Total duration ~20 minutes, topical anesthesia (drops), discharge the same day. Visual recovery begins that very evening, while full stabilization, including neuro-adaptation, takes 3 to 6 months.

Frequently asked questions — Multifocal implant
Will I really be able to do without glasses entirely?
In 90 to 95% of patients, yes, for everyday life. The remaining 5 to 10% use a light supplementary correction for specific tasks (prolonged reading of tiny print, fine sewing, night driving on a dark motorway). No formal guarantee can be given; the individual response depends on the anatomy and on neuro-plasticity.
Are the halos bearable?
Yes, for the great majority of patients. The halos are perceived during the first 2 weeks as “light coronas” around headlights, then the brain learns to filter them out. At 6 months, fewer than 5% of patients find them bothersome in daily life.
Can a trifocal be implanted if I have already had LASIK?
Yes, under certain conditions. LASIK modifies the cornea and changes the calculation of the implant power. It is essential to provide Dr Tourabaly with your pre-LASIK measurements (if available). Specific calculation formulas (Haigis-L, Barrett True-K) are then used to secure the accuracy of the result.
Should a trifocal be implanted in both eyes?
Yes, ideally. To take full advantage of multifocal technology, binocular consistency is needed. Placing a trifocal on one side and a monofocal on the other gives less satisfactory results, except for a “mix-and-match” strategy discussed on a case-by-case basis (e.g. trifocal in the dominant eye + EDOF in the non-dominant eye).
What happens in the event of dissatisfaction?
Lasting dissatisfaction is rare (< 3%). The options are: (1) wait for full neuro-adaptation at 6 months, (2) treat any residual astigmatism with LASIK or PKR, (3) in extreme cases, perform an implant exchange, a more complex surgical procedure but a possible one.
Is the multifocal implant suitable for intensive night driving?
Less so than the monofocal or the EDOF. If you are a professional night driver, a long-haul driver or a taxi driver, Dr Tourabaly will generally favor a premium aspheric monofocal or an EDOF, which better preserve contrast sensitivity in mesopic conditions.
Are you eligible for a trifocal?
A full assessment determines in 1h30 whether the trifocal is right for your eyes and your lifestyle.

Multifocal vs EDOF implant comparison: which choice for you
The main alternative to the multifocal is the EDOF implant (extended depth of field). Both have their place but address different priorities:
- Multifocal — aims for total independence from glasses, including for fine reading. Acceptance of night-time halos is required. Ideal for a patient ready for the neuro-adaptation investment and who wants to minimize glasses.
- EDOF — excellent distance and intermediate vision, with fine reading sometimes requiring an aid. Night-time halos are markedly less pronounced. Ideal for a patient cautious about halos or who drives a lot at night.
Individual sensitivity to halos is the single most important deciding factor. A thorough discussion during the consultation, taking into account your night-driving habits and your emotional outlook toward optical trade-offs, is essential before deciding.
Candidate profiles for the multifocal implant
The ideal candidate for a multifocal implant has several converging characteristics:
- Strong motivation for independence from glasses, including for prolonged fine reading.
- Intact retina — no AMD even at an early stage, no diabetic retinopathy, no epiretinal membrane and no macular edema. A good-quality preoperative macular OCT is indispensable.
- Moderate corneal astigmatism or astigmatism correctable with a toric multifocal implant. Irregular astigmatism (subclinical keratoconus) is a contraindication to multifocality.
- No major psychological fragility regarding night-time halos; neuro-adaptation can take 4 to 12 weeks, sometimes longer. Patients who are anxious about transient visual symptoms adapt less easily.
- Varied professional and leisure activities, with needs at every distance.
Night-time halos and acceptability
Halos and glare (positive dysphotopsia) are the almost inevitable optical trade-off of multifocality. Their intensity varies with the implant model, the patient’s scotopic pupil diameter and individual sensitivity. Recent studies on new-generation trifocals report bothersome halos in 5 to 15% of patients after the neuro-adaptation period, most often attenuated or well tolerated beyond 3 months.
To anticipate this phenomenon, I systematically present concrete illustrations of the type of halos to expect during the consultation, and I ask the direct question: “Would you rather see a few halos in exchange for no longer wearing glasses?” Your spontaneous answer is often the most reliable indicator of your profile.
Key figure
An international meta-analysis on multifocal implants reports a satisfaction rate of 85 to 95% in well-selected patients, with a spectacle independence rate of 70 to 90% (Rosen et al., JCRS 2016, PMID 27026457).
