Advantages of keratopigmentation

The keratopigmentation technique provides both aesthetic (iris colour) and functional (the tattoo’s opacity to light) correction. This technique is quite old, as attested by Indian publications dating from 1950. Colouring using a tattooing technique was updated for the modern day by VAN DER VELDEN, particularly for the cornea. Although the first indications involved the aesthetic treatment of corneal opacity (leukoma), the treatment is now used on the irises of seeing eyes.

There are undeniable advantages:

  • A non-puncturing corneal overleaf incision (superficial, in relation to the iris).
  • Manual (crescent knife or spreader) or femtosecond laser dissection. Simple placement of pigment in tunnel using a spreader or micromanipulator.
  • The paste-like consistency of the pigment prevents the need for corneal stitches.
  • The colour and opaqueness of the pigment enables both visual functional issues (product is opaque to light) and the aesthetic appearance of the iris to be corrected at once.
  • Recovery is simple with nearly no side effects.
  • This technique is easy to perform and can be performed on seeing eyes.

Technical limitations

The cornea must be sufficiently thick to withstand an intrastromal incision and the creation of a ring-shaped cavity.
