Evidence-based recommendations on ab externo canaloplasty for primary open-angle glaucoma in adults. This involves widening the eye’s main draining canal by inserting a tiny tube, then removing the tube and stitching the canal to keep it open.

This guidance replaces NICE interventional procedures guidance on canaloplasty for primary open-angle glaucoma (IPG260).

Guidance development process

How we develop NICE interventional procedures guidance

Your responsibility

This guidance represents the view of NICE, arrived at after careful consideration of the evidence available. When exercising their judgement, healthcare professionals are expected to take this guidance fully into account. However, the guidance does not override the individual responsibility of healthcare professionals to make decisions appropriate to the circumstances of the individual patient, in consultation with the patient and/or guardian or carer.

Commissioners and/or providers have a responsibility to implement the guidance, in their local context, in light of their duties to have due regard to the need to eliminate unlawful discrimination, advance equality of opportunity, and foster good relations. Nothing in this guidance should be interpreted in a way that would be inconsistent with compliance with those duties.

Commissioners and providers have a responsibility to promote an environmentally sustainable health and care system and should assess and reduce the environmental impact of implementing NICE recommendations wherever possible.
