Eye color changing surgery in Turkey

Thanks to the superior features of the Lumineyes 8G laser, the dark pigmented layer is destroyed by the laser before activating the brown or dark pigmented cells in the iris. It protects the second layer, which gives the green-blue-hazel-gray color. This protection feature, which can never be copied, is one of the main factors that makes Lumineyes laser eye color changing process unrivaled.

You can be sure that we have had a lot of success. Most people who want to change their eye color use the “Mylumineyes” laser eye color changing method. This method lowers the amount of melanin in the iris, which changes the color of the eye.

The pigment in the frontal iris determines the color of the eye. Any color, including iris, consists of three components: color, intensity, and valuation. Colour is a mixture of fundamental colors , intensity is the color’s contrast with white on the color range, and valuation is the colour’s luminosity or light reflection.

Dr. Mete developed the Lumineyes Xtra procedure, which employs a laser to remove dark environments pigmentation that gives brown eyes their color.

This laser shots creates a biological reaction in iris and provacate macrophages activity to clean deead cells. MYLumineyes  requires no stay in hospital and takes five minutes daily. Additionally, there was no discomfort during the surgical procedure. The quantity of eye laser sessions required will vary according to your eye color and preferred color. Laser eye color surgery is still undergoing research studies, but in principle, a low-energy laser would be used to eradicate the dark brown eye colors, resulting in green,grey,hazel or blue eye colors. Lumineyes Laser can change the appearance of your eye color while giving most attractive eye colors that is appealing.

The laser treatment initiates a photothermolysis reaction that activates the front iris area in MYLumineyes. The colored material is removed via the capillaries as a consequence of immune and macrophage reactivity to the the therapy, disclosing the deeper grey stromal tissues of the iris. Laser eye color change is permanent, but due to the superior technology of Lumineyes Xtra, if you are dissatisfied with the color of your eyes or there is insufficient change in eye color, you have the option to repeat the procedure until you achieve the desired, attractive eye color.

If laser treatment is administered by incompetent personnel and is incompatible with the Lumineyes procedure, these risks tend to be extremely high

Vision loss or blindness, corneal trauma that cause problems with vision, and cataracts are among the risks. The potential hazards of permanent blindness and reduced vision outweigh the aesthetic benefits of eye color change by a wide margin.

The Lumineyes procedure employs a low-intensity laser on the the iris for less than one microsecond to eliminate the stroma, or light-absorbing fibers in the iris. After a stratum has been wiped out, the body will eliminate it naturally. 

As a result, the following new features have made the “Lumineyes method” perfect:

1. The unique characteristics of the Fluency technique type
2. selectivity
3. diagramming
4. variability
5. individuality
6. short-term memory
7. reliability
8. wavelength
9. Tissue-friendly

Another important element is that “Mylumineyes” generates unique programs for each patient while adhering to safety rules.

Do I need to make preparations in advance?

For the Mylumineyes laser procedure, there is no requirement for any sort of preparatory work in advance. Obviously, every precaution has been taken to protect your health.

What we check in your eyes before starting laser session?

1. Your eye characteristics.
2. The anatomy of the iris.
3. Pigmentation type
4. Drainage canals.
5. The density of the pigmentation.

Am I able to continue using my contact lenses?

Still, you are free to continue your existing practise of using coloured contact lenses. Unquestionably, long-term contact lens use has an increased risk of permanent eye damage. Mylumineyes are advantageous to general wellness. In addition, the expenses involved with eye colour change surgery are more economically viable in the long term than those associated with contact lenses. Changing the colour of one’s eyes using a laser is the healthiest alternative.

Undoubtedly, the important thing is how and with whom you change your eye color.

There is no doubt that using a laser to change your eye color in a natural way is possible. Two considerations are of the utmost importance for persons who change the color of their eyes. In a nutshell, the level of expertise possessed by the attending physician as well as the appropriateness of the laser type.

What should I concentrate on eye color changing?

Doubtedly, eye color changing operations conducted by unlicensed and incompetent centers will inevitably result in serious eye problems in the future! Eye physiology The capacity of the aqueous humor drainage channels to expel spilled pigments is limited. Too much effort or pigmentation placed on channels too quickly will result in canal failure. This will result in major eye health issues. Consequently, glaucoma, iridocyclitis, cataract, korneal injury, and iris atrophy will result from incompetently performed eye color change treatments!

1. As was already shown, there is no channel overload with the Mylumineyes technique.
2. Exercise caution as cheap and improper laser methods may easily result in permanent eye damage.
3. All else is significantly less precious than your sight. Do preliminary investigation on phoney physicians, clinics, companies without an address, and companies and clinics you have never heard of.
4. You should be aware of amateur and fraudulent clinics. Their numbers have increased during the past years.
5. We urge that you conduct extensive research on the physician.
6. Be wary of brokers whose websites lack a physician’s name.
7. Additionally, investigate your physician’s medical history.

What is the age restriction for eye color change?

For persons at least eighteen years old and no older than sixty, lasers may alter the color of their eyes. No matter whether their family has signed a permission document, no one under the age of eighteen may have this surgery done.

I have a myopia-hypermetropia-astigmatism-presbyopia problem. Am I suitable for changing my eyes?

Of course, you may change your eye color. If you wish, we can also correct your other eye problems. It is a well-known fact that Dr. Mete is also a very good lasik eye surgery specialist.

Changing eye color with laser method is currently the most reliable and effective way

Basically, this laser activates the natural mechanism of the eye and offers a healthy eye color change. Moreover, the results are completely natural, not artificial. We not only invented the first laser eye color change treatment, but we also improved on it regularly. We’d like to underline that using any other copy technique than Mylumineyes puts you at risk. We realize very well that everyone’s time is valuable and moreover, many people prefer to acquire results early. Undoubtedly, you are enduring a long voyage, labor and labor loss.

The Lumineyes laser color change surgery is both safe and natural. Moreover, the effect of changing eye color lasts for 4-6 months. In summary, Mylumineyes’ laser technology is 99 percent effective and safe. As a result, the only way to change eye color quickly and safely is to professionally apply the Lumineyes method with an 8-g laser.

What is the success rate for an eye-color-changing laser?

If we use Lumineyes Xtra, we have a 99.9 percent success rate, even on the most challenging eyes. This rate is over 90% in standard lumineyes.

Which laser is most effective for changing eye color?

Above all, selecting melanin pigmentation is greatly simplified with the “8G+ 3D MyLumineyes laser”. Maximum performance and eye safety are two key features of this technology. Unquestionably, the safest and healthiest way to change the color of your eyes is using the MyLumineyes® laser. MyLumineyes utilise a separate wavelength. It only chooses melanin pigmentation on the iris, leaving the rest of your eyes unaffected. Additionally, the 8G+ 3D Laser offers the best possible outcomes. Unquestionably After 15 years of research, we’ve discovered that the only method to safely change the color of your eyes is using MyLumineyes® laser eye color changing surgery.

Unsuccessful eye color change surgery

I had eye color change surgery, but I got unsuccessful results. What can I do? In fact, there is a solution, of course. After the unsuccessful eye color change procedure, many people who are looking for a laser hope to have a laser again and achieve the eye color they dream of. First of all, as we have mentioned before, your ophthalmologist’s ability, experience, and the laser device used must be suitable for this job. Despite this, there must be many suitable conditions for the eye color to change. People with dark brown eyes may need more than one therapy session to change their eye color. Undoubtedly, after the unsuccessful eye color change procedure, we achieve success with the “Mylumineyes Xtra” program that we use in our clinic.

We used a different algorithm and parameters to change the eye color in eyes with Mylumineyes Xtra. This successfully provides color change in the eyes. While more effective shots are made to the DNA structure and pigment resistance, which are responsible for the change in eye color, at the same time, the problems existing in the iris are tried to be eliminated. Iris problems that we frequently encounter arise with the use of lasers that have both high energy and flammable effects.

What can you do after unsuccessful eye color change surgery?

After an ineffective eye color change procedure, a detailed eye examination is performed in our clinic . With the “Mylumineyes Xtra” program, the factors that prevent the process from being successful are evaluated. In many cases, the process of changing your eye color with a laser, which does not produce results, is successful.
You should know that the probability of failure with “Mylumineyes Xtra” is very low. This method usually gives results after 1–4 therapy sessions. For a successful eye color change surgery, everything has been considered.

As a result, you can achieve the highest success rate with Mylumineyes Xtra. Moreover, even if you have done eye color change before. Everything you need for successful eye color change surgery is in Mylumineyes Xtra.

We recommend that you read our other informative articles on our site in order for the results of the eye color change surgery to be successful.

Does eye color change without surgery?

First of all, the laser color change procedure is not a surgery.
Laser beams pass through the corneal layer and create an effect on the iris. Simply put, no surgical procedure is required. In fact, the laser eye color change in Turkey does not involve any kind of surgery or invasive treatment. Another very important advantage of the Lumineyes method is that there is no contact with your eye, even a lens or any other tool.

What is the difference between old Lumineyes standart and Lumineyes Xtra?

In summary, the main difference between the two methods is that almost all risks associated with the lumineyes method have been successfully corrected by Doctor Mustafa Mete, making it an excellent eye color changing method.

Both the safety and effectiveness of Lumineyes XTRA procedure is outstanding. Mylumineyes Clinic’s work on heterochromia has resulted in laser eye color-changing technology. Remarkably, other clinics try to implement mylumineyes-style procedures, but it is not possible to copy it. Compared to “Mylumineyes Eye Color Change Türkiye,” these centers face numerous disadvantages. First of all, the treatments applied at our center using Lumineyes and 8G lasers do not burn or damage the iris pigments, unlike their counterparts around the world.

The 8G Luineyes lasers cause changes in melanin pigments.

TheLumineyes 8G laser in use boasts the latest safety technology. Therefore, it is safe to alter eye color. This laser recognizes the melanin pigment in the iris and acts only in areas with melanin. In addition, other tissues of the eye do not absorb the wavelength used by the laser device. This prevents damage to other eye tissues. When exposed to laser energy, melanin cells undergo changes. Thus, the iris color begins to lighten slowly.There is a natural process that the 8G laser uses as well, but we’d rather not reveal it just now.

Interestingly, the two-minute laser treatment for each eye is really brief. The treatments are completely painless and will leave you feeling quite comfortable. Lumineyes provide exceptional comfort. Everyone has a varied number of sessions, energy levels, and shots.

What is the most advanced eye color change laser method for changing the color of your eyes?

The 8G Lumineyes laser is definitely the cutting-edge technology available for the “eye color change process.” The application of this technology varies depending on each individual’s unique eye structure. Considering everything, the “Lumineyes 8G” laser is the best choice because it is both effective and safe.

Sorry, but you cannot choose the final color. In general, it is impossible to predict the eye color that will occur after laser treatment.

No way. You cannot select this option prior to the laser treatment. After the treatment, the color of your eyes is uncertain and unpredictable. Dark brown, highly pigmented eyes are prone to changing to gray, green, or hazel, whereas light brown eyes are likely to change to blue, gray, and green. The change in eye color also depends on the resilience of the dark pigments that are already there. Mylumineyes works by safeguarding eye health without exceeding boundaries. Surprisingly, with our most recent innovation, we have the option to pick between blue and green in certain instances. Dr. Mete continually updates and develops Mylumineyes. Additionally, we believe that if you are sincerely committed and take your therapy seriously, we will be able to assist you in reaching your dreams.

Do you feel pain? When will I be able to return to my job?

During laser-assisted eye color change, you will feel nothing but a slight prickling sensation; you will not be uncomfortable. After therapy, the patient can resume normal activities. In general, there are no substantial changes in your life before and after laser eye surgery; nonetheless, you should avoid strenuous activities.

Is changing your eye color with laser permanent?

As mentioned before, all eye color changes caused by Lumineyes are permanent. Keratopigmentation surgery does not have a permanent effect like laser. Apart from this, return is possible if the lens inside the eye is removed after iris implant surgery. In the meantime, you should definitely stay away from iris implants.Indisputably, the only natural, healthy, and effective way to change eye color permanently is laser treatment. In Turkey, permanent eye color change provides the best results. There is no need to repeat this operation. Because of the one-of-a-kind procedure that mylumineyes uses, the eye color change is permanent.

The first thing to remember in mind is that the structure of your eye’s DNA and its many small characteristics are crucial factors in determining the outcome.

Various factors can influence the color change that happens in the eye. Basically, the DNA, eye health, pigment ratio, pigment resistance, provided response, and other factors influence the results. Each eye and body properties adds a little something to the end result. The outcome is that some eyes may need as few as four sessions and others as many as forty.

The procedure to change the color of my eyes did not work. How would you feel if I persisted in our relationship?

If your eye health has remained in outstanding condition and you received the therapy from an actual doctor, then the answer is yes. There is still time for you to change your eye color in Turkey so that it is proper.

What is the distinction between darkness and light brown eyes?

Because the results are subjective and can increase or decrease depending on the person’s expectations, there is no objective indicator of a good result here. The lightening of the color in the eye has almost no bounds. The time it takes to achieve results in people with light brown eyes is usually short, and the number of sessions is low. Contrarily, dark eyes will usually require longer treatment and more sessions. Except in exceptional cases, this rule is 75 percent accurate. Consequently, this means that people with dark brown eyes will need to come in for additional sessions every 4–6 months. Until they are completely satisfied with their results. In short, the most ideal candidates for permanent eye color change surgery with laser are light-medium dark brown and hazel eyes.

Don’t start treatments to change your eye color until you don’t have these problems.

• Diabetes (not under control)

• People with high eye pressure are being watched, especially those with closed angular glaucoma.

  *people with open-angle glaucoma can get treatment because Lumineyes helps this disease.

• Rheumatic diseases

• uveitis, and iridocyclitis

• Individuals with undiagnosed systemic diseases 

   

• Individuals born without an iris

• You have high expectations.

• Inflammatory bowel disease (IBD) or other systemic disorders

• Psychosocial insecurity

• Taking drugs that cause deposits in the retina or cornea.

Those who have at least one of the aforementioned disorders are ineligible for Lumineyes laser eye color change without surgery procedure.

Is eye color changing safe in Turkey?

Unquestionably, an ophthalmologist with extensive surgical experience can administer this type of laser treatment. In addition, the center must possess extensive expertise in this field.t. Significantly, “Mylumineyes” is the most secure and successful approach for changing eye color. Long-term findings have demonstrated that the MYLumineyes® procedure is quite safe. Mylumineyes is at least as secure as Lasik. However, this is not true of other approaches.

What Are the side effects of Laser Eye Color Change Surgery?

As i have said, these side effects only occur in unknown laser eye color changing processes.

1. Iridocyclitis-Pigment Dispersion Syndrome
2. Glaucoma
3. Cataracts
4. Permanent visual loss
5. Uveitis
6. Eye inflammation symptoms
7. Corneal injury-stem cell failure
8. Unsuccessful result
9. iris atrophy

Patients who receive Lumineyes Standard and Xtra do not experience the above risks in the short or long term.

There are places that guarantee results and are cheaper, why you do not guarantee?

Sadly, we’ve heard this story from multiple sources. They are investing time, hope, money, and most importantly, their eye health. Please refrain from having discussions of this nature. As you can see, color-changing surgery is a serious procedure. Please do not change your eye color in locations where it would be harmful or unrecognized. As a result, surgery to change one’s color is a serious procedure. First thing to remember, please do not change your eye color in places where it is unsafe or unrecognized. In the final analysis, watch out for places that pop up every six months and fake social media accounts that boast about how well they’re doing. Due to our ethical guidelines, the “eye color change Turkey clinic” prioritizes your health and refrains from making unfulfillable promises.

Is it possible to get VIP treatment and service for changing my eye color in Turkey?

For a small extra fee, you can get this for sure. We make treatment plans that are unique for each patient. These plans may include hotel stays, car rides, and tour guide services so that you can change the color of your eyes while you’re on vacation.

Unquestionably, iris implant surgery is very risky, stay away

Shortly, “Iris implant surgery” is the process of placing a silicone lens on the iris (the pigmented layer of the eye). Using this method, it is possible to create an artificial eye color. Contrary to popular belief, this technique has been in use for many years. This surgical process was used for post-traumatic or congenital iris damage problems. Currently, we do not favor this method, which is less complicated than the laser method. It has an artificial appearance, a very high number of complications, and unsatisfactory results. In other words, according to the laser eye color change procedure, it is a risky procedure with long-term complications. As a result, implant surgery cannot achieve the natural-colored appearance that the laser provides. It is thought-provoking that many people are blinded by iris implant surgery despite our repeated warnings.

Indeed, there is no empirical evidence to substantiate the efficacy of eye drops that change the color of the individual’s eyes.

Various internet platforms provide eye drops that claim to change the color of one’s eyes. We can categorize these dips into two distinct classes.

1-prostaglandin analogs
2-drops that purport to change eye color.

First, this topic is highly contentious. Prostaglandin analogs used to treat glaucoma can produce darkening of the eyes and elongation of the eyelashes. This is indeed a side effect. If the objective is to lighten the iris color, prostaglandin analogues will have the opposite result. If you use these eyedrops in only one eye, you will cause heterochromia. Second, n-acetylglucosamine eye drops, which have been shown to change the color of the eyes. In addition, n-acetyl-glucosamine inhibits melanin formation in the skin. On the other hand, its effect on the eye remains uncertain. Furthermore, it does not enter the eye via the skin. If it passes, it is unknown what kind of damage it will create. We believe that this chemical will have no influence on the iris’ melanin pigment.

Drops that change eye color have no efficiency

Lastly, we have observed numerous favorable and critical comments changing this eye drop on various media and social networking sites. Some celebrities claim that they have used these eyedrops on their own eyes with positive effects. Obviously, these are almost certainly ads. Additionally, you should not put this chemical in eyedrops or in your eyes.
It is only safe for skin contact. The cost of eye drops that change eye color without FDA or other authorisation is 55 USD online. Additionally, there are options for various eye colors. I would want to warn you that there have previously been drops that claimed to address all problems. They were, however, proven to be ineffective..

Keratopigmentation surgery, with its associated side effects and use of artificial colors, unquestionably has drawbacks when compared to laser procedures.

Keratopigmentation surgery can be performed using a “femtosecond laser.” This process has two distinct steps. Initially, the surgeon forms a tunnel within the cornea. Injecting a colored substance into this channel is the second step. Tattooing the cornea results in a permanent eye color change. Patients with cloudy corneas or other problems that make them look bad have been getting corneal tattooing for a long time. Keratopigmentation permanent eye color change surgery has no effect on the eye’s natural pigments. On the contrary, it gives a false impression. Lastly, keratopigmentation surgery causes a lot of complications. First thing to remember that the “Laser Eye Color Change Procedure” uses a natural process.

What are the potential long-term concerns associated with keratopigmentation?

Dr. Mete limits keratopigmentation to patients with trauma or iris issues. In 2024, Dr. Mete stated that those who have had keratopigmentation will encounter significant difficulties during future cataract surgeries. Dr. Mete asserts that cataract, retina, and most other eye surgeries restrict the eye surgeon’s field of view. Consequently, the majority of eye surgeries either remain unperformed or entail significant risk.
