Elimination of monocular diplopia by corneal tattooing

Corneal tattooing to eliminate monocular diplopia secondary to surgical peripheral iris defects was performed successfully in two patients who were unable to tolerate contact lenses. The technique is simple, safe, cosmetically satisfactory, and eliminates the need for patient compliance with contact lens care. Although corneal tattooing is usually considered to have only cosmetic value, these patients demonstrate that it can be therapeutic as well.
