Corneal Tattooing
Also known as
Keratopigmentation.

What is a Corneal
Tattoo?
A Corneal Tattoo is a procedure which is performed by
chemical reduction of metallic salts, gold chloride or
platinum black, to either cover up an unsightly corneal
scar or to mimick part or all the iris.
The metalic salts are
place at a 50% depth into the cornea through a peripheral
incision and blended to ensure it covers the area it
needs to.
How common is this
procedure?
This procedure is very rare, I have only heard of one
case where a person with congenital aniridia had this procedure.
This is because the procedure would have implications on
the need for further eye surgery, such as glaucoma
treatment or the development of aniridic Keratopathy.
Therefore, if this procedure is used it is usually on an
eye that has no vision at all. A team at the the Rotterdam Eye Hospital, successfully used this proceedure to reduce photophobia in a patient with traumatic aniridia.
