Discussion
Although recent survey data from Wolffsohn et al8 suggest ECPs across the world are engaging more with myopia management, discussion with both primary and secondary care ECPs demonstrates that myopia management is not yet fully integrated into UK eyecare, and there is inconsistent accessibility for patients across different areas of the UK.
There are some possible reasons for this discrepancy. In Wolffsohn et al,8 the analysis of UK-specific practitioners’ data was limited in favour of a broader comparison between continents, possibly diluting the specific responses of the 67 UK respondents. The qualitative nature of this current study allowed a more contextual investigation of attitudes and barriers relevant to the UK specifically. The differences in selection bias between the two studies are not known, and like the current study, the global survey gained information on subjective attitudes to myopia management prescribing rather than objective data from prescribing rates in practice.
Some of the barriers to myopia management reported in this study share similarities with those previously reported in studies across the world. Specifically, affordability of treatment, scepticism over treatment efficacy, constraints on consultation time, lack of specialist equipment, and insufficient clinical guidelines.8–13
A previous focus group study conducted by McCrann et al19 was performed in Ireland in 2019 on the same topic. There is a large overlap in perceived barriers between their results and the results of this current study, likely due to a similar scope of practice between the two nations. This suggests that some of the barriers present in the prior study are also reported within the UK currently. Barriers such as poor financial incentives for practices to adopt myopia management, and ECPs struggling to balance clinical care and meet daily sales targets, are noted in both studies. Shickle et al24 suggested the pressure for retail revenue in the UK arises from a systemic problem within primary eyecare. They reported that under the current NHS contract, the fee for an eye examination in England, Wales and Northern Ireland does not cover the cost of conducting the examination. Subsequently, practice owners must subsidise this deficit through maximising appointment numbers and subsequent sales. Therefore, re-evaluation of the GOS contract is recommended, reassessing the remuneration for standard eye examinations and other additional services now offered by primary care practices, including myopia management.
Affordability of treatment was identified as a leading barrier toward the wider adoption of myopia management. ECPs felt that affordability is a heightened concern for UK parents because they are accustomed to compensated eyecare under the NHS. Interestingly, data from an international survey of 1009 parents in 2019 reported that UK parents attributed more importance to the treatment affordability than parents from other countries.25 Cost of treatment appears to concurrently discourage ECPs from offering treatment, especially to those perceived as unable to afford it. ECPs enquired as to whether NHS funding would soon be available to alleviate the current socioeconomic bias. In Scotland, an analysis of GOS payment claims for children’s single-vision spectacles found greater GOS claims in deprived areas,26 suggesting that NHS provision enables wider accessibility for those unable to afford these services outside of the NHS remit. However, such provision would likely require appraisal from the National Institute for Health and Care Excellence (NICE). As many aspects of myopia management are not currently definitive, including their mechanism(s) of action,27 substantial work is likely required to produce the necessary evidence for NICE approval.28
Parental scepticism appeared as a significant barrier to uptake, and ECPs reported having to work hard to encourage treatment uptake. In the recent members’ survey by the Association of Optometrists (AOP), 64% described the profession as ‘undervalued’, believing there to be poor public understanding of the importance of eye examinations and eyecare.29 Focus groups with UK adults found that optometrists are often viewed as retail workers, rather than healthcare professionals.30 31 As such, their advice is viewed as less trustworthy than other healthcare professionals, such as general practitioners (GPs) or dentists. More effort is needed to promote the value of ECPs and the importance of paediatric eyecare in the UK. ECPs in this study suggested that a public health initiative to promote awareness of myopia management would help achieve this aim.
The need for up-to-date, specific myopia management guidance for ECPs was frequently discussed and is echoed from the previous focus group work by McCrann et al19 in Ireland. For secondary care ECPs, there has been guidance published by the World Society of Paediatric Ophthalmology and Strabismus, and the European Society of Ophthalmology.32 33 However, the scope of practice is different between countries, and atropine is not currently licensed for myopia management in the UK, therefore ophthalmologists would benefit from UK-specific guidance. Regarding primary care ECPs, both the College of Optometrists and ABDO published updated guidelines during the period of data collection for this study.34 35 The new College of Optometrists’ update came more than 3 years after the first set of guidance and took a firmer stance than the original guidance. However, it appears that many ECPs, particularly those with less experience, are still seeking a more prescriptive approach to myopia management. An example includes ECPs seeking clarification over when to initiate and cease treatment, as well as determining whether they are expected to refer patients to another practice if suitable myopia management options are unavailable, and whether failure to do so would amount to negligence. Providing definitive guidelines is difficult in an emerging field of research with several areas of uncertainty,26 and a more prescribed approach does not necessarily fit with the patient-centred approach recommended by the IMI.36
From these data, ECPs seem to exhibit low tolerance towards the uncertainty that comes with individualistic decision-making in myopia management. This partly appears to stem from anxiety over potential malpractice claims and litigation. Anxiety over misdiagnosis has been reported among other healthcare professions, for example GPs, and may lead to the practice of ‘defensive medicine’, whereby management of a patient is based on fear of litigation, rather than on best practice or patient well-being.37 An increase in defensive practice has also been noted among optometrists through increased false positive referral rates,38 including for neuro-ophthalmology, following the high-profile case of undiagnosed papilloedema in an 8-year-old patient in 2016.39 Davey et al40 found that false positive referrals generated by optometrists decrease with experience at a rate of 6.2% per year, indicating that newly qualified ECPs take a more conservative approach to management decisions, which is consistent with the findings reported here. While it is understandable that ECPs may wish to practise cautiously, defensive medicine can increase pressure on services that are already struggling, resulting in lower-quality care and an economic impact.39 This was supported by the opinions of ophthalmologists who indicated they wanted myopia management to remain within primary eyecare.
While ECPs in McCrann et al19 suggested their lack of myopia management knowledge was a major barrier, this appears not to be the case in this current study, possibly due to an abundance of learning material that has become available over the past few years. Instead, UK ECPs more often stated confidence and experience as barriers to prescribing. Therefore, more emphasis should be placed upon practical experience of myopia management during foundational ECP training, and an emphasis on how to deliver individualised clinical care more confidently. In lieu of a stricter blanket approach to management, ECPs would also benefit from a regularly updated, UK-relevant review of recent scientific evidence to support their clinical management decisions, not reliant on commercial sponsorship. Clarity over whether ECPs are expected to manage pre-myopes and progressing adult myopes would be helpful, as the current evidence is less developed.41 42
This study did have limitations. As per figure 2, there was over-representation of independent and academic ECPs, and an under-representation of ECPs from national chains, compared with proportions found in the latest GOC registrant survey.43 Additionally, there was over-representation from the Northwest of England and under-representation from the devolved nations, particularly Northern Ireland. There is also likely volunteer bias, whereby those attending may have a greater interest in myopia management, and the data may therefore not fully represent the wider ECP population. However, the relatively equal split between practitioners with and without experience in myopia management may help to mitigate the impact of such bias. It is important to note that these data are subjective reports from ECPs, rather than objective data on ECPs’ prescribing behaviour, and hence may also be liable to response bias.17
Future work may benefit from investigating differences between ECPs and their preferred choice of intervention. A peer-reviewed, UK-specific survey on myopia management with a larger sample size may improve generalisability and provide quantifiable statistics on preferred choice of management interventions and prescribing rates. Also, exploring any discrepancies between ECPs’ and parents’ perceptions could help to further understand the barriers to successful myopia management adoption across the UK.
In conclusion, myopia management seems to be implemented inconsistently across the UK, with various barriers preventing an optimal service. ECPs would appreciate more frequent, unbiased updates to clinical guidance, with clear information about clinical and legal expectations. There appears to be overarching issues with the financial compatibility of eyecare services and myopia management within the current UK primary eyecare model. Increased accessibility to myopia services in primary care, without compromising quality, can only be achieved if key stakeholders, such as educational and professional bodies, industry, and ECPs themselves acknowledge current barriers and work to enact change at all levels of eyecare delivery.
