The Neoris technique
- What is the limbal ring?
The limbal ring is the dark ring at the edge of the cornea. It is said that the limbal ring makes the look more attractive.
The Neoris technique makes it possible to create a limbal ring: it can be thick or fine. It is also possible to change the color without a limbal ring.
- Why does the pupil not move anymore after the operation?
The real pupil continues to work normally, but it is less visible and is located behind the false motionless pupil created by the surgery.
- Can the Neoris keratopigmentation cause glaucoma?
No. The Neoris technique only involves the cornea. It is therefore highly unlikely that it can lead to glaucoma.
- Is the procedure painless?
The procedure is performed under a local anaesthetic administered through simple eye drops. The
surgery is not painful.
The patients may experience tingling or dryness in the eyes days or weeks after the procedure, but these symptoms are normal and disappear rapidly.
- Why does the colour not cover the iris up to the centre of the eye?
The cornea is a transparent dome-shaped tissue that lies in front of the eye and that lets the light through to the retina. Making the edges of the cornea more or less opaque by inserting the pigment to it has no effect on the eyesight. However, pigmenting the centre of the cornea would severely limit the field of vision.
In addition, it would be more difficult for an ophthalmologist to properly examine the back of the eye, and some operations (such as cataract surgery) would also be difficult to perform.
- Can you operate on dark eyes?
Yes. The result is actually better for dark eyes (grade 4 and 5) than for light eyes.
- Does the eye colour look natural after the operation?
From very close and under intense lighting, an attentive person will be able to see that the colour of the eyes has been retouched. From about 50 cm away and under moderate lighting, the eye appears natural. In the evening and by a low light the colouring is less visible.
- How long does the change of eye colour last?
The colouring is permanent. It is possible that the colour fades or lightens after a couple of months or years, especially if exposed to strong sunlight. In such cases a retouch is possible.
- What are the ingredients of the dye?
The pigment used by Neoris is made in France. The dispersion consists of a natural vegetable
equivalent of propylene glycol and of PH modifiers (lactic acid or Na-hydroxide depending on the
The pigments consist of a mixture of:
- iron oxides (yellow + red + black) and titanium for a brown colour,
- chromium oxides, ultramarine and titanium dioxide for a green colour,
- Ultramarine, copper phthalocyanine and titanium dioxide for a blue colour,
- black iron oxide and carbon for a black colour.
- Can myopia be operated in the same procedure?
If you also wish to undergo refractive surgery (myopia operation, astigmatism operation, hypermetropia operation or presbyopia operation), you must carry out a topography eye test with your ophthalmologist before your Neoris operation.
- If the topography eye test is normal, then you should start by changing the colour of your eyes and then undergo the refractive surgery, waiting at least 3 months after the Neoris operation.
- If keratoconus is detected during the topography eye test and laser surgery is impossible, you should firstly undergo refractive surgery with the insertion of an implant and then go for the Neoris operation at least 3 months after the refractive surgery.
- Are there alternatives to Neoris?
There are several alternatives to Neoris, such as:
- wearing coloured lenses:
This is by far the most frequently used method. However, it should be noted that the complications associated with wearing coloured lenses are more frequent than the complications related to wearing transparent lenses.
- incorporation of coloured silicone implants into the eye:
This technique regularly causes complications that can be very serious. Several cases of blindness have been described following the placement of these implants.
- laser depigmentation of the iris:
This method has an extremely low success rate. Only 10% of patients are satisfied with the results:
- The result is visible only after many laser sessions and most often the final colour tends to be a faded gray. It is impossible to choose a colour
- This technique does not work with highly pigmented eyes (grade 4 and 5).
- A repigmentation is common after 1 year.
- In addition, serious complications such as glaucoma, are possible.
Unlike all these alternative techniques, keratopigmentation developed by Dr. Ferrari and promoted by Neoris has recorded excellent results. Practised since 2013, this method has already proved itself over time.
Keratopigmentation, which is offered exclusively by Neoris, is the only surgical technique that can change eye colour permanently and safely. The opthalmic surgeons, members of the Neoris Alliance who are eligible to practice keratopigmentation, are carefully trained by the inventor of this technique. They are obligated to follow a special medical protocol and have a compulsory insurance in order to be allowed to perform this unique procedure.
- wearing coloured lenses:
- What is the price of the eye changing operation?

- What are the payment options?
The Neoris fee must be paid online by credit card or wire transfer prior to the first consultation.
Likewise, the surgery can be paid for by credit card or online bank transfer before the intervention. It can also be paid on the day of the procedure by credit card at the clinic.
We do not accept checks.
- Is it possible to pay in instalments?
- At what minimum age can I undergo the surgery?
The minimum age is 21 years old.
- Where can I undergo the surgery?
The procedure takes place only in ophthalmic surgery clinics scrupulously selected by Neoris on the basis of the quality of their technical equipment. At the moment, surgery is performed in two centres:
Clinic “Espace Nouvelle Vision”
6 rue de la grande chaumière, 75006 Paris, France
The interventions take place on Thursdays.
It is advisable to arrive in Paris on the evening preceding the intervention.
Thursday morning will be devoted to a series of ophthalmic exams carried out in order to confirm the information gathered by the doctor during the first consultation. Once this is done, the surgeon will see you for a further consultation.
The surgery will take place on Thursday afternoon.
A postoperative check-up will take place on Friday morning, the day after the procedure.
A second check-up takes place 3 months after the intervention.
Clinic “Expert Vision Center
27 route de l’Hôpital, 67100 Strasbourg, France
The interventions take place on Wednesdays.
It is advisable to arrive in Strasbourg on the Tuesday morning preceding the intervention. Tuesday afternoon will be devoted to a series of ophthalmic exams carried out in order to confirm the information gathered by Dr. Ferrari during the first consultation. Once this is done, Dr. Ferrari will see you for a further consultation.
The intervention will take place on Wednesday afternoon.
A postoperative check-up will take place on Thursday morning, the day after the intervention.
A second check-up takes place 3 months after the intervention.
- Are there any special requirements prior to the operation?
At the first meeting organized by Neoris you will discuss the procedure with the surgeon who will operate on you. He will tell you about all the risks that are inherent to this intervention and you will be asked to report your medical history. This first contact between the patient and the practitioner is essential and mandatory before any intervention. This meeting can take place in person or via a video conference at least 15 days before the intervention.
- Will my identity documents still be valid after the operation?
No, because your appearance will have changed. Therefore, it will be necessary to renew your identity documents after the operation.
- What happens during the first meeting?
The first appointment is not a typical medical consultation, but rather a non-committal and free-of-charge talk that the doctor gives to all those interested in changing the eye colour with the help of the Neoris-technique. He will explain the technique and guide you through all risks inherent in this procedure. Moreover, you will have a chance to tell him or her about your expectations and your medical history.
This meeting can be held either face-to-face or, if you happen to live far away from our clinics, online. The conversation can be held in English, German or French, depending on your level of proficiency in these languages.
