Eyeball tattoos are a risky cosmetic procedure, and complications usually show up within weeks. But a new case report describes a patient who did not experience problems until eight years after the tattoo was applied.

The patient had the conjunctiva tattooed so the white part of the eye would appear black. The delayed adverse event is unusual and suggests that some complications may take years to surface, far beyond the typical follow-up window.

While this is a single case, it underscores the importance of monitoring patients long after such procedures. Clinicians should be aware that eyeball tattoo-related issues may not always present early.
