#knowyourdrops eye drop compliance campaign to achieve medicines optimisation in ophthalmology

Moorfields Pharmacy has launched a Trustwide #knowyourdrops eye drop compliance campaign together with the International Glaucoma Association, to promote best eye drop techniques, raise awareness of why using eye drops correctly is essential, and educate patients/carers and health professionals on the various compliance aids available, to achieve medicines optimisation in ophthalmology.

The numerous examples of improved care and quality of life for patients/carers is remarkable, confirming the campaign’s value to optimise medicines and patient outcomes.


With many patients having poor dexterity or vision, aiming eye drops correctly at the correct angle or squeezing plastic containers can be challenging. Furthermore, some patients perceive asking for support as wasting clinical time; others feel embarrassed to admit they cannot administer drops correctly or easily; and others do not realise that they have poor technique.

Overall, this can result in poor clinical outcomes or lead to financial losses with excessive dispensing due to patients using several drops at a time to administer one drop accurately. Furthermore, polypharmacy and repeat dispensing can potentially be avoided if techniques are correct in the first instance.

All our patients are reviewed and counselled on eye drop compliance and techniques, and continual support assessment is vital to aid compliance through a multidisciplinary team approach.  The pharmacy and clinical directorate team therefore decided to raise awareness of compliance and eye drop techniques, offer enhanced support and reduce barriers to good compliance techniques and treatment failures through the #knowyourdrops campaign.

The International Glaucoma Association is greatly supporting #knowyourdrops because eye drop compliance, especially for glaucoma, is key for effective outcomes.

#Knowyourdrops consists of a one-day advertised event at each Moorfields site, of which there are around 25 satellites spread across London, with advice and information on the Trust’s website and Twitter – including a useful online video and an opportunity to live tweet compliance-related questions.  Engagement with local clinical commissioning groups, GPs, our community partners and local eye networks also helped raise further awareness. Our lead consultant opens the #knowyourdrops session by speaking about compliance and eye drop techniques to all patients/carers, inviting everyone to talk to us for a review and advice.

We integrate with the clinical team by providing patients with a dedicated pharmacist-led patient consultation demonstrating best techniques, raising awareness of compliance, and demonstrating various compliance aids which may support treatment.  We have an eye catching patient-facing stand with information. During the pharmacist-led consultation, we review with patients/carers their treatment/side effects related to compliance issues. We also deliver interactive lunchtime workshops to all staff, emphasising best eye drop techniques and assessments, and available compliance aids.

Feedback has been very positive with 100% of patients/carers so far reporting #knowyourdrops has improved ability and confidence administering eye drops. The numerous cases including increased compliance, reduced polypharmacy, reduced side effects, and reduced need for carers to assist with administration, Overall, it demonstrates that the #knowyourdrops campaign helps achieve medicines optimisation in ophthalmology.
