Keratopigmentation (Corneal Tattoo) and Prosthetic Contact Lenses

Abstract

Prosthetic contact lenses and corneal tattooing have been used for both cosmetic purposes in nonfunctioning disfigured eyes and for therapeutic purposes in functioning eyes. For example, they are used in aniridia to avoid glare and double vision. In blind, disfigured non-painful eyes, these techniques have the advantage of low cost and the avoidance of more invasive procedures such as conjunctival flaps, evisceration, and enucleation. In certain patients with a close to normal-sized globe and minimal disfigurement, contact lenses are preferred for creating the best match to the contralateral eye. The lenses are commercially available in different iris diameters, colors, and base curves. However, if a more precise match is desired, prosthetic contact lenses can be hand painted and customized. On the other hand, when only acceptable cosmesis and lower maintenance are desired, or in patients with intolerance to prosthetic contact lenses, corneal tattooing can be used. Different dye materials, surgical techniques, and results have been described.
