The National Institute for Health and Clinical Excellence (NICE) has issued guidance on photorefractive (laser) eye surgery for the treatment of refractive errors (short and long-sightedness) to determine whether it is safe enough and works well enough for use.
Risks include failure to achieve the expected improvement in unaided vision, development of new visual disturbances, corneal infection, and flap complications.
These risks should be weighed against the risks and any possible inconvenience of wearing spectacles or contact lenses. NICE also advises clinicians to audit and review clinical outcomes of all patients who have laser eye surgery. Further research will be useful and clinicians are encouraged to collect longer term follow-up data.
