Changing eye colour is possible, but there are limitations
This technique was originally developed to correct iris defects and has become a dream for many people, although it carries risks to eyesight.
Changing eye colour is a cosmetic procedure that many people dream of. Until now, this was only possible through the use of contact lenses, but, due to high demand, surgical techniques have been developed in recent years that make this change permanent.
Today, these procedures have become popular on social media as a permanent solution for those who wish to choose the colour of their eyes. Currently, there are three main procedures: iris implants, laser depigmentation and cosmetic keratopigmentation.
However, professionals warn of the dangers of subjecting the eyes to these procedures, as they are highly complex and can pose risks to eyesight.
What determines eye colour?
Our eye colour is determined by our DNA, the result of a process that is far more complex than was thought until a few years ago. In fact, the HudsonAlpha Institute for Biotechnology explains that “scientists have discovered that at least eight genes influence the final eye colour”. These genes regulate the amount of melanin in our iris, the pigment responsible for colouration.
However, the colour of our eyes goes far beyond a specific shade. Each person has a unique combination, resulting from a blend of colours, ridges and patterns, which is as individual and distinctive as a fingerprint.
Surgical techniques for changing eye colour
There are currently three surgical procedures that allow the colour of the eyes to be altered:
- Cosmetic iris implants: an artificial iris is inserted over the natural one to change the colour.
- Cosmetic keratopigmentation: this involves injecting pigment of the desired colour directly into the cornea. To do this, a tunnel is created in the corneal tissue using a laser, through which the pigment is introduced to achieve the desired colour.
- Laser depigmentation: this does not add colour to the iris but rather removes some of its pigment to lighten the eye colour.
These procedures were originally developed to treat specific eye conditions or defects that affected the appearance of the eye or visual health. Now, however, almost 91% of patients undergo these procedures for cosmetic reasons, according to some studies.
All procedures carry risks
Current evidence suggests that the three techniques for changing eye colour may pose a risk to eye health. Below is a comparison of the aesthetic limitations of each surgical procedure and the risks they may entail:
The safest option for changing eye colour
The eyes are extremely delicate organs that can easily suffer permanent damage. Therefore, before undergoing any cosmetic surgery to change their colour, it is essential to consult a trusted ophthalmologist.
Currently, the least invasive way to change eye colour is through contact lenses, provided they are used correctly and under the supervision of a specialist. Furthermore, make-up techniques and the use of accessories can also be great allies. Although they do not change the natural colour of the iris, they can create optical effects that help to lighten or enhance the colour in a natural way.
In conclusion
Sight is one of the senses we use most in our daily lives. Therefore, maintaining good vision and good eye health is important. Here are some tips from the American Academy of Ophthalmology for looking after your eyes:
- Maintain a varied diet with fruit and vegetables rich in vitamins A, C and E.
- Exercise regularly and stay well hydrated.
- Protect your eyesight, whether by wearing sunglasses when outdoors or safety goggles when carrying out activities that could damage your eyes.
- Take breaks and limit screen time to prevent eye strain.
Furthermore, it is recommended that you visit an ophthalmologist regularly to have your eyesight checked and ensure your eyes remain in good health.
