Keratopigmentation, also known as corneal tattooing, is a revolutionary procedure designed to permanently change the apparent color of the eye. In recent years, keratopigmentation has gained popularity for both cosmetic and therapeutic purposes. The procedure involves placing specially colored pigments into the superficial cornea. A highly experienced surgeon uses advanced bladeless femtosecond laser technology to create meticulously crafted corneal channels in a circular fashion around the pupil. These channels are customized according to each individual's corneal anatomy, with proper centering and symmetry being crucial for natural-appearing results.1
Keratopigmentation vs. Traditional Methods
To understand the significance of keratopigmentation, it's essential to compare it with traditional methods of eye color modification.
Colored Contact Lenses
Colored contact lenses have long been a popular choice for those seeking to change their eye color temporarily, offering a wide range of color options, including natural-looking shades and more dramatic, theatrical effects. They are generallyColored contacts are the safest option for changing one's eye color.Image by Africa Studio at Adobe Stock considered the safest option for altering eye color, especially when prescribed by an eye care professional. However, non-prescription cosmetic lenses carry a higher risk of complications and should be avoided.3
Iris Implants
Iris implants, initially developed for medical purposes, have been adapted for cosmetic use. The procedure involves inserting an artificial iris made of silicone through a slit in the eye. While FDA-approved for patients with iris defects due to injury or birth defects, their use for purely cosmetic reasons has raised serious concerns amongst medical professionals.
Complications associated with cosmetic iris implants can be severe and even vision-threatening. These include reduced vision or blindness, elevated intraocular pressure leading to glaucoma, cataract formation and corneal damage that may necessitate a transplant.3 Due to these risks, many medical professionals consider the implantation of cosmetic iris implants to be malpractice.2
Laser Iris Lightening
Laser iris depigmentation is an emerging technique that uses a frequency-doubled 532-nm wavelength neodymium:YAG laser to remove pigment from the iris. While it appears to be safer than cosmetic implants, this method is not without its risks. Cases of iris perforation have been reported, and its effectiveness on dark-pigmented eyes is limited, often requiring multiple sessions with minimal noticeable results.4
In contrast, keratopigmentation, particularly femtosecond-assisted cosmetic keratopigmentation (FLAK), has shown promising results. Studies have reported excellent stability of pigmentation patterns over time, with no signs of ocular toxicity or significant changes in vision. A prospective study of 79 eyes with an average follow-up of 29 months revealed a high rate of patient satisfaction (92.5%) and no significant changes in topographic, pachymetric or refractive values.2
The Keratopigmentation Procedure
Preparation
Before the actual keratopigmentation procedure, a qualified ophthalmologist experienced in this specialized procedure performs a comprehensive consultation. During this initial meeting, practitioners should discuss the patient’s motivations, expectations and overall eye health. A thorough pre-operative evaluation follows to assess the condition of the cornea, iris and general eye health to determine patient suitability for the procedure.4
The patient then selects their desired iris color. Practitioners should make sure to set proper patient expectations, ensuring they understand that the final result may be influenced by their natural eye pigmentation. Before proceeding with the surgery, the patient signs an informed consent form, acknowledging the potential risks, benefits and complications associated with keratopigmentation.
The Surgery Process
Ensuring proper centering and symmetry of pigment is crucial for natural-appearing results.Image by Алексей Доненко at Adobe StockKeratopigmentation is typically performed under local anesthesia, ensuring patient comfort throughout the procedure.4 The surgery utilizes advanced bladeless femtosecond laser technology, specifically the VisuMax laser (Zeiss), to create meticulously crafted corneal channels.1 The procedure is performed as follows:
The surgeon marks the center of the cornea and designates the pupil diameter using a specialized marker.2
Using a femtosecond laser, the surgeon creates a micro-tunnel in the corneal stroma, the middle layer of the cornea.5
The surgeon then injects specially prepared color pigment particles into these channels using a fine cannula.2
The pigment is carefully placed in a circular fashion around the pupil, with proper centering and symmetry being crucial for natural-appearing results.1
The entire process takes roughly 25-40 minutes for both eyes, and doesn’t affect the internal structures of the eye or involve an eye implant.1
Recovery & Post-Procedure Care
Post-procedure, discussing and providing detailed instructions for eye care during the healing process is vital to prevent complications. Practitioners may prescribe eye drops or medications to prevent infection and reduce inflammation.4 In the first 24 hours following the procedure, patients might experience mild discomfort, which can be managed with over-the-counter pain relievers and soothing eye drops provided by the clinic.1
Sensitivity to bright light may occur within the first 24-72 hours post-procedure. Patients are typically prescribed two types of eye drops: one to prevent infection and another to aid in the healing of the eye surface.1
Follow-up appointments with patients to monitor the eye's healing progress helps ensure no complications arise.4 The results of keratopigmentation are immediate, but it is important to emphasize that full recovery and stabilization of the new eye color may take some time.5
Controversy Surrounding Keratopigmentation
Keratopigmentation has sparked significant debate within the medical community and among regulatory agencies. While the procedure has shown promise in addressing certain functional and cosmetic eye issues, it has also raised concerns about safety, ethics and long-term effects.
Concerns Within the Medical CommunityImage by Vadim at Adobe Stock
The American Academy of Ophthalmology (AAO) issued a warning against keratopigmentation, citing a range of potential risks.5 Possible risks include:
Corneal damage leading to cloudiness, warpage, fluid leakage and vision loss
Light sensitivity
Inflammatory reactions to the dye, including uveitis or blood vessel growth into the cornea
Bacterial or fungal infections resulting in corneal scarring or vision loss
Uneven distribution of the dye
Dye leakage into the eye
Color fading due to dye movement
These concerns highlight the need for caution when considering keratopigmentation for cosmetic purposes. The AAO recommends colored contact lenses as a safer alternative for those seeking to change their eye color, emphasizing that these should be prescribed and fitted by qualified eye health professionals.6
Regulatory Status
Keratopigmentation is not currently FDA-approved, raising questions about its safety and efficacy.5 This lack of regulatory approval means that the procedure is not covered by insurance, making it a potentially costly option for patients. The absence of official oversight has led to concerns about the standardization of techniques and the qualifications of practitioners performing the procedure.
Ethical Considerations
The rise in popularity of keratopigmentation on social media platforms has raised ethical concerns within the medical community. Many individuals are pursuing the procedure for purely cosmetic reasons, rather than addressing serious health issues.6 This trend has led to medical professionals expressing concern about the appropriateness of performing potentially risky procedures solely for aesthetic purposes.
Moreover, the permanent nature of keratopigmentation stands in stark contrast to safer, temporary alternatives like colored contact lenses. This irreversibility adds weight to the ethical considerations surrounding the procedure, as patients must carefully weigh the long-term implications of their decision.5
As the controversy surrounding keratopigmentation continues, it remains crucial for practitioners to carefully weigh the benefits and risks for each individual patient seeking this procedure and discuss the seriousness of this irreversible procedure and its risks before coming to a final decision.
Patient Experiences
Success Stories
Keratopigmentation has had a significant impact on many patients' lives. One individual reported feeling transformed after the procedure, stating that it changed their life. The dramatic difference in eye color, from brown to green or blue, has led some patients to feel like different people externally, even if they remain the same inside.5 A patient who had previously undergone unsuccessful laser depigmentation found keratopigmentation to be a safer option for achieving a more dramatic change.7
Reported Complications
While many patients report positive experiences, some have encountered complications. In a study of 204 patients, 12% experienced complications, primarily consisting of light sensitivity and some fading of the pigment. Another study involving 40 patients found that roughly one-third reported light sensitivity.8
Common post-operative symptoms include pain (81% of patients), dry eyes (76%), glare (56%), red eyes (67%) and tingling (71%). However, these symptoms were generally temporary, with approximately 50% of cases resolving within 48 hours for pain, tingling, glare and red eyes.4 Dry eye symptoms typically lasted longer, with an average duration of 7 days for patients experiencing symptoms longer than 48 hours.
Overall Satisfaction Rates
Despite potential complications, patient satisfaction rates for keratopigmentation appear to be high. In one study, the average satisfaction score with the aesthetic result was 8.1 out of 10.4 Patients also reported an average improvement in well-being of 2.8 on a scale of 0 to 4 following the procedure. Another study found an average postoperative patient satisfaction score of 4.18 out of 5 points.9
The high satisfaction rates may be linked to the transformative nature of the procedure. Many patients report feeling more comfortable with their appearance after keratopigmentation.5 However, it's important to note that some patients (around 7%) opt for additional procedures to adjust the shade.8
Final Thoughts
Keratopigmentation has certainly made a noticeable impact on the fields of ophthalmology and aesthetics, offering a permanent solution for eye color change. While it shows promise in addressing certain functional and cosmetic issues, it also raises concerns about safety and ethics. The high satisfaction rates among patients highlight its transformative potential, but the reported complications and lack of FDA approval underscore the need for caution.
As research continues, it's crucial to carefully weigh the risks and benefits of this procedure. The ongoing debate within the medical community is helping to encourage further studies and potentially lead to safer, more refined techniques. For now, though, exploring temporary options like colored contact lenses under professional guidance remains a safer alternative for patients interested in altering their eye color.
