Eye color change, from advertisement to reality

Keratopigmentation (KTP): iris beauty coloring in simple language 🎨

What is keratopigmentation?
KTP is a "corneal tattoo" procedure that aims to change the appearance of eye color. In this method, instead of manipulating the iris, a very fine channel is created with a laser in the stroma of the cornea and the pigment is placed inside to create a new color similar to the iris.

Usages:
• Changing the beauty of the eye color ✨
• Covering corneal scars 🩹
• Improving the appearance of the eye after iris injuries or abnormalities 🩺

Does this work on the iris?
No. The iris cannot be manipulated at all. A color effect is created in the cornea and acts like a cosmetic layer on the front surface of the eye ✨

POTENTIAL RISKS TO THE EYE ⚠️
Although this procedure is advertised as “safe”, it is still invasive and has real risks, including:
• Infection – bacterial or fungal keratitis 🦠
• Inflammation – chronic irritation or photosensitivity 🔥
• Corneal opacity or scarring – causing glare, halos and reduced vision
• Pigment displacement – color change or inconsistency 🎨
• Increased intraocular pressure – due to inflammation 📈
• Chronic discomfort – foreign body sensation or pain 😣
• Challenge in future surgeries – measurements for LASIK/PRK/cataract may be disturbed ⏳
• Dissatisfaction with final color – result may not match patient's expectation ☹️
