How we develop NICE interventional procedures guidance

Coding and clinical classification codes (updated July 2022) for this guidance

The coding guidance has been updated in line with IP1862 Ab interno canaloplasty for open-angle glaucoma as we consider the canaloplasty a procedure on the trabecular meshwork.

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