Guidance
The National Institute for Health and Clinical Excellence (NICE) has issued full guidance to the NHS in England, Wales, Scotland and Northern Ireland on Phototherapeutic laser keratectomy for corneal surface irregularities.
Description
Eye disorders in which the outer clear layer of the eye (the cornea) becomes scarred, uneven, less flexible, or develops recurrent ulcers may result in loss of ability to focus sharply.
Phototherapeutic keratectomy uses a laser to remove layers of the cornea in order to produce a smooth, even surface with the aim of improving vision.
Coding recommendations
