Corneal tattooing, commonly referred to as eye tattooing, is a medical procedure with a long history. Used for cosmetic or therapeutic purposes, this technique has evolved from ancient practices to modern medical advancements. Historical records show that Galen and Aetius were among the first to apply pigments like powdered hazelnut, iron, or copper sulfate to the eye, following cauterization of the corneal surface.
- In 1869, oculoplastic surgeon Louis von Wecker pioneered the use of corneal tattooing by applying a thick solution of India ink to the cornea and then tattooing it using a needle.
- Taylor introduced a method using a bundle of needles instead of a single one.
- In 1901, Nieden designed a tattooing needle resembling an electric fountain pen.
- Today, various techniques, such as multiple intrastromal ink injections, manual interlamellar approaches, superficial automated methods, and femtosecond-assisted keratopigmentation, are commonly used.
An Overview of Corneal Tattooing Through History
Ancient Era
Corneal tattooing can be traced back to as early as 1500 BCE. Physicians in Ancient Rome and Greece used this technique to treat ocular conditions. For instance, the Roman physician Galen was among the first to describe corneal tattooing as a treatment for opaque corneal lesions. Pigments at the time were derived from natural sources like charcoal or plant-based dyes.
Medieval and Renaissance Periods
During the Middle Ages, corneal tattooing evolved as a cosmetic technique to conceal corneal opacities or whitened eyes. Surgeons focused on improving patients’ appearances for aesthetic purposes. However, the methods were primitive, and the pigments often failed to adhere effectively to the tissue.
19th Century
Modern corneal tattooing gained renewed interest in the 19th century. Christoph Heinrich Weller from Germany suggested using ink to camouflage whitened corneas resulting from blindness. Techniques were refined with sterilized needles and more suitable pigments, ensuring safer and more effective procedures. The primary aim during this period was cosmetic correction.
20th Century
Advances in ophthalmology during the 20th century modernized corneal tattooing. Micropigmentation techniques improved precision and safety. Common applications during this period included:
- Concealing corneal whitening caused by trauma or disease.
- Changing eye color for cosmetic purposes.
- Addressing aesthetic concerns in conditions such as aniridia.
21st Century
In the 21st century, corneal tattooing has advanced significantly with the introduction of laser technologies and biocompatible pigments. These modern methods are less invasive and better aligned with patients’ aesthetic expectations. Techniques like laser-assisted keratopigmentation are now widely used for purposes such as changing eye color or concealing corneal scars.
Medical and Cosmetic Applications
- Medical Purposes:
- Enhancing the appearance of individuals with corneal scars or opacities that cause aesthetic concerns.
- Cosmetic Purposes:
- Changing eye color or achieving a desired aesthetic appearance based on patient preferences.
Despite its ancient origins, corneal tattooing continues to evolve alongside technological advancements, serving as both a medical and cosmetic solution for a range of ocular concerns.
