Corneal tattooing

Corneal tattooing is a medical procedure that involves tattooing the cornea of the eye. This practice has been performed for centuries, with its primary purpose being to improve the cosmetic appearance of the eye in cases where the cornea has become disfigured due to injury, infection, or previous surgery. In addition to its cosmetic applications, corneal tattooing can also serve therapeutic purposes, such as reducing glare or light sensitivity in patients with corneal scars.

History

The history of corneal tattooing dates back to the late 19th century, when it was first documented by ophthalmologists. The technique has evolved over time, with significant advancements in the tools and inks used, making the procedure safer and more effective.

Indications

Corneal tattooing is indicated for patients who have corneal scars that impair their cosmetic appearance or cause functional problems like photophobia (sensitivity to light). It is often considered after other treatments, such as corneal transplant or contact lenses, have been deemed unsuitable or ineffective.

Procedure

The procedure involves the use of a fine needle to introduce pigment into the corneal stroma, the middle layer of the cornea. The choice of pigment color is typically made to match the patient's natural iris color, although in some cases, contrasting colors may be used for cosmetic effect. The procedure is usually performed under local anesthesia and can take anywhere from 30 minutes to an hour, depending on the complexity of the case.

Risks and Complications

As with any medical procedure, corneal tattooing carries risks and potential complications. These may include infection, allergic reactions to the pigment, and accidental damage to the cornea. However, with proper technique and post-operative care, the risks are minimal.

Aftercare

After the procedure, patients may be prescribed antibiotic and anti-inflammatory eye drops to prevent infection and reduce inflammation. Follow-up visits with the ophthalmologist are important to monitor the healing process and ensure the success of the tattoo.

Conclusion

Corneal tattooing is a valuable procedure for patients seeking to improve the cosmetic appearance of their eye due to corneal disfigurement. While it carries some risks, advancements in technique have made it a safer and more effective option for eligible patients. As with any medical procedure, patients should consult with a qualified ophthalmologist to discuss the potential benefits and risks.
