Colour stability and resorption
The results of eye colour change operation using the Neoris keratopigmentation technique are permanent.
However, we regularly receive questions about colour stability. It is sometimes possible to observe more or less important resorptions of the dye according to the colors and the patients.
Why do the eyes lose colour over time?
This is a natural phenomenon, which may be heightened by extensive exposure to sunlight. The pigment is then absorbed by the cornea, and the colour tones down as a result.
However, it does not lead to any particular eyesight problems, pain or irritation. And some patients show no signs of resorption a year after the operation.
In any event, this is NOT a cause for concern! The result is very good, and even if the colour is a bit less intense, it will not disappear. What is more, it is highly likely that the colour will still be there fifteen to twenty years after the procedure, even without being touched up. However, since eye color change surgery with Neoris keratopigmentation has only been performed since 2013, we can’t say for sure.
Are some colours more liable to resorption than others?
Some of the colors of the old range show a fairly significant resorption.
Therefore, while waiting for new and more stable dyes, we prefer to offer only the Riviera Blue and Emerald Green dyes.
Are there any ways to limit such resorption?
There is indeed a solution for brightening the colour in order to make it more intense. This is simply a touch-up. That is done by injecting a small quantity of pigment once again in order to heighten the colour density. However, this intervention cannot be repeated indefinitely.
When does the colour need retouching?
It is not possible to give a frequency of retouching, since the speed of resorption varies between patients and pigments. For some, this may occur after a few weeks or months, while for others, resorption is not seen until several years after the procedure. Each person is different.
Many patients find that resorption makes their colour look more natural over time. As the color naturally soaks into the cornea, the color tends to fade, becoming more evenly embedded in the eye.
In short, even though the keratopigmentation technique leads to a permanent change in eye colour, resorption has been found in some patients. Be reassured, this process is completely normal, safe, but almost unavoidable, and can be easily corrected.
