Change the color of the eyes , from brown to blue, seems to be a reality in some ophthalmological clinics thanks to the new Neweyes laser , which removes melanin from dark eyes until they become clear. However, although performing this procedure is technically feasible, we must be cautious and take into account the possible associated risks , still unknown above all in the medium and long term.

These risks do not derive so much from the surgical act itself, that is, from the application of the laser, but from the fact of depigmenting a naturally pigmented eye , which could have a negative effect on the intraocular structures.. One of the factors to keep in mind is that the laser does not disintegrate or volatilize, as it sometimes can in some movies. This means that the melanin particles that are detached from the iris by the impact of the laser do not disappear and remain in the eye, which must eliminate them.

This is where one of the main problems may arise, since the structures responsible for filtering the internal ocular fluid may not be prepared to eliminate a high concentration of pigment particles and, therefore, could be obstructed by altering the intraocular pressure.. A progressive and cumulative increase in this pressure, by breaking the natural balance of the eye, could constitute a high risk to visual health over the years.

On the other hand, it would be necessary to verify if the elimination of melanin at an early age, which is in itself a protection for the eye against ultraviolet rays , could cause other harmful effects. It is possible that an excessive ocular exposure to solar radiation could be harmful or toxic over time, since it is no coincidence that in the hottest areas the eyes are also, as a rule, darker.

My opinion, in short, is that it is still early to know if this new technique is truly reliable for the change of eye color, in addition to viable. Therefore, before applying it with total guarantee to patients, we must be sure that its consequences are only aesthetic, ruling out any risk to vision ... not only of immediate effect, but also in the long term, when more serious ocular complications may arise. A follow-up time of three to five years would probably be enough.
