change eye colorfrom dark to light, or vice versa, went from being a dream for some to becoming into reality thanks to the various techniques available, an aesthetic desire that It went viral on social media. but that the Spanish Society of Ophthalmology (SEO)drecommended due to the irreversible consequences can have for vision.
One of the techniques is keratopigmentation, which possibly a famous influencer has used these days, and which consists of iIntroducing a pigment that stains the cornea using a so-called femtosecond laser -also used in other eye surgeries- to obtain the desired shade.
The SEO warns how patients undergoing this intervention suffered corneal decompensations that lead to loss of its transparency.
multitude of risks
“I have seen some cases of young people with significant bilateral corneal decompensation, caused by the tattoo, who needed a corneal transplant”, indicated the undersecretary and ophthalmologist of the SEO José Antonio Gegúndez.
Even in the case of not needing a transplant, the medical director of the EyeCos Clinic in Barcelona and member of the Professional Association of Spanish Ophthalmologists (APOE) Pedro Grimaldos warned that a possible cataract intervention or retinal operation would not be possible because the cornea needs to be transparent.
“I don’t recommend it for scientific reasons. It’s a surgery, you don’t work on the iris, the iris doesn’t change color, you work on the cornea where the dye is placed in front… The dye covers your visual field, you can’t see it from the sides and creates a peripheral visibility problem”, explained Grimaldos to EFE.
In addition, he warned that the intervention can generate a rejection since a foreign body is introduced into the body and the result is not regular or homogeneous.
“Keratopigmentation is attractive for its immediacy”, he lamented, and considered that in many cases, the risks are not explained and future incompatibilities for other surgeries.
best contact lenses
In addition to damage to vision, the result is superficial and causes what has been called “doll eye” or “robot eye“, according to Gegúndez, who recommends that those who want to show off other eye colors use cosmetic lenses occasionally and wait for science to accredit other types of interventions that are safer and more effective.
The doctor and professor of Ophthalmology at the Miguel Hernández University (UMH) of Elche, Jorge Alió, who defended in a statement that keratopigmentation is a technique backed by scientific research of more than ten years and that it is the “most studied and widely researched”.
The other technique that allows you to change the color of the eyes is the laser iridoplastydefended by the doctor Pedro Grimaldos, who promises a “true change” in the color of the iris without going through the surgical center, just with the whitening of this tissue.
Therefore, it would no longer be a question of staining the cornea as in keratopigmentation, but of working directly on the iris until it is cleared, a practice that does not allow choosing the color, but would be determined by the genetics of each patient.
Since it began to be applied in 2011, almost five thousand people have undergone this procedure, explained Grimaldos, who guaranteed that he had not seen “chronic long-term complications” and that the results have been published in international magazines and books.
On the contrary, SEO considers that this technique that actually changes the color of the iris could cause a dispersion of pigment inside the eye that would give rise to glaucoma, which can lead to loss of vision.
