1.1 Dexamethasone intravitreal implant is recommended as an option for treating diabetic macular oedema only if:
the implant is to be used in an eye with an intraocular (pseudophakic) lens and
the diabetic macular oedema does not respond to non‑corticosteroid treatment, or such treatment is unsuitable.
1.2 People whose treatment with dexamethasone intravitreal implant was started within the NHS before this guidance was published, but is not recommended for them by NICE in this guidance, should be able to continue treatment until they and their NHS clinician consider it appropriate to stop.
