The National Institute for Health and Clinical Excellence (NICE) has issued full guidance to the NHS in England, Wales, Scotland and Northern Ireland on corneal implants for the correction of refractive error.


Short-sightedness is the inability to see clearly at a distance. Eyesight can usually be corrected by wearing spectacles or contact lenses. The insertion of clear plastic implants into the cornea is an interventional procedure aiming to restore eyesight in short-sightedness.

Coding recommendations

C46.4 Insertion of prosthesis into cornea

Excludes: Insertion of therapeutic contact lens (C51.5)

In addition the ICD-10 code H52.1 Myopia would be recorded.
