New Zealand has led the way in scope change for nurses and optometrists in ophthalmology. Changes were made to optometrists' scope of practice in 2005 and 2014 to increase the range of therapeutic pharmaceutical agents they could prescribe and, still somewhat controversially, in 2022 to allow specially trained hospital-based optometrists to perform ophthalmic laser surgery. New Zealand nurses also now deliver the bulk of anti-VEGF injections in the public system, run crosslinking, glaucoma and macular degeneration clinics and deliver other minor ophthalmic interventions such as laser.
While more than three-quarters of Australian optometrists are endorsed to prescribe scheduled medicines, OA has struggled to expand their scope of practice further, said Hadyn Treanor, president of the New Zealand Association of Optometrists (NZAO). “Optometry in New Zealand continues to have a wider scope of practice than that in Australia,” he said, noting that the Australian Government is required to approve the recommendations of the Australian optometry regulatory body, the Optometry Board of Australia, which is not the case with the Optometrists and Dispensing Opticians Board (ODOB) in New Zealand.
Where Australia does have a clear advantage is its existing funding model for subsidised eye tests, something that does not exist in New Zealand, he said. “This gives it a significant advantage in using the highly skilled optometry workforce in a true primary healthcare capacity.”
Following the ODOB’s targeted consultation in 2023 on extending hospital optometrists’ scope of practice to include IVI, the NZAO is undertaking the work required to progress the scope expansion for hospital-based optometrists and develop a relevant training programme.
The ODOB is supportive of further expansion to allow New Zealand’s hospital-based optometrists to give anti-VEGF injections, said Suzanne Halpin, ODOB chief executive and registrar. Compared with their Australian counterparts, New Zealand optometrists’ scope of practice has broadened substantially over the past decade, she said. Optometrists in Aotearoa can prescribe any Medsafe-approved medication within their scope of practice; hospital- and ophthalmology clinic-based optometrists are involved in the therapeutic management of patients with systemic conditions including hypertension, diabetes and auto-immune conditions; they can apply for an endorsement to their scope of practice, allowing them to independently manage glaucoma cases (optometrists in Australia cannot do so without collaboration with an ophthalmologist); and suitably trained optometrists can perform minor surgeries, such as the removal of conjunctival concretions and certain types of laser surgeries, she said. “Any change to the regulatory settings in Australia that would make it simpler to align the practice of optometry between Australia and New Zealand would be welcomed by the ODOB,” she added.
