Table 3 Summary of opportunities to improve the environmental sustainability of the NHS dry eye disease care pathway.

From: Achieving net-zero in the dry eye disease care pathway

Time bound

Strategy

Short term

• Independent sector Carbon offsetting

• Raising awareness of NHS net-zero through adapting public health strategies

Mid-term

• Expansion of recycling schemes like TerraCycle

• Eco-friendly cardboards and clearer recycling instructions in secondary packaging

• More local delivery of care (community optometry workforce, Primary Eyecare Companies and diagnostic and treatment hubs)

• Introducing electric vehicles and delivery management systems (e.g., pharmacies and NHSBT)

• Government funding to promote sustainability through innovations and research

• Regulating Carbon emissions and sustainability progress of NHS suppliers

• Training NHS staff on environmentally sustainable healthcare

• Development of teleophthalmology and necessary support services

Long-term

• Increased use of multi-dose bottles and alternative drug delivery systems

• Adaptation of biodegradable packaging products like the Notpla Pipette to create 100% biodegradable single dose eye drops vials

• Improving municipal recycling processes so small items are recycled

• Reducing the cost of alternative therapies

• Electronic devices harnessing renewable energy and recyclable plastics

• Further research to reduce dependence on cold chains and improve environmental sustainability of cold chains

• Further research around new eye drops formulations including head-to-head studies to compare efficacy and therapeutic duration in subgroups

• Better digital connectivity between community eye services and NHS hospitals

• Development of artificial intelligence to help triage and diagnose patients

• Expansion of NHSBT facilities
