When we look at the human eye, what we call eye color is the visible color of the structure we call iris. What gives color to iris is the color pigments on it. The darker the appearance of these pigments. In the eyes of blue people, these pigments are either very small or absent.
Changing eye color is currently possible in two ways:
I – Laser Application Method:
If these pigments are removed in people with high-density pigments, the color of the iris is opened and clear eye color is formed. This can be seen in some diseases (such as Fuchs, Heterochromic iridocyclitis). One way to artificially remove the pigments is to apply laser energy accordingly. In this way, the iris pigments are poured and the iris color is opened. The color that will be formed after the pigments are removed is related to the color and fiber structure of the iris underneath. It is not possible to determine this in advance. However, the eye color of the blue color will be opened with different shades. If color pigments are appropriately diluted, a greenish color can also be obtained.
The theoretical side effects of this laser treatment are as follows:
1-Glaucoma (increase in intraocular pressure): This may be caused by the pigments being clogged by the pigments called the trabecular meshwork that drains the intraocular fluid. However, this is not a common practice since laser pigments are disintegrating and shrinking.
2-Cataract: It is a situation that can be caused by the application of the laser accidentally on the lens or by using unsuitable laser energy. There is almost none in the applications made by experienced physicians.
The color change occurs slowly. The ideal results are taken between six months and one year.
II – Implant Method:
In front of the iris, which gives the eye the color, a body resembling an iris is placed. The advantage of the implant is that the desired color can be obtained, the procedure is short. Although the placement of existing implants is relatively easy, long-term side effects are high.
1-Glaucoma (eye pressure): The long-term friction of the implant due to iris pigments and the trabecular network called the trabecular network can be formed by the clogging of the structure draining the intraocular fluid.
2-Iris Deformities: The iris tissue deteriorates with friction and occasional adhesion of the implant to the iris.
3-Corneal Endothelial Insufficiency: Since the implant rubs into the endothelial layer, which is the innermost layer of the cornea, a continuous endothelial cell loss is experienced. If endothelial cells fall below enough number from a few months to a few years, the condition we call endothelial failure occurs. The horn is blurred and the visual acuity decreases. Cornea transplantation may be needed.
4-Cataract: The implant may develop as a result of touching the lens and/or prolonged non-microbial inflammation (inflammation).
5-Infection: As in every attempted eye infection, there is also an intraocular infection risk.
