Back to ortho-k basics: from hesitation to confident recommendation

Orthokeratology has long been part of the myopia management toolkit and is supported by the most extensive evidence base among available myopia control interventions.¹  Yet in everyday practice, it is not always positioned as a first line option. Some practitioners may feel unsure about where to begin, while others may have drifted away from fitting ortho-k over time. This article returns to first principles, focusing on how to approach ortho-k in a structured and practical way, from treatment selection through to patient communication, to support greater confidence in incorporating it into routine care.

Ortho-k has demonstrated robust efficacy in slowing myopia progression. It has consistently shown to slow axial elongation by approximately 50% over at least one year compared to single-vision spectacle or contact lens wearers.^2-5  A study found that ortho-k reduced axial elongation by 0.69 mm over 11 years compared to single-vision lenses, which demonstrates long-term efficacy.⁶ 

Beyond efficacy, ortho-k offers unique practical advantages that other modalities do not:

• Freedom from daytime optical correction: Ortho-k eliminates the need for glasses or contact lenses during waking hours, which is particularly beneficial for children involved in sports or other physical activities.
• No reliance on daytime compliance: Since ortho-k is worn during sleep, this removes the risk of a child not wearing their spectacles or daily contact lenses during the day.
• Improved self-esteem: Children wearing ortho-k lenses report higher satisfaction with their appearance and ability to participate in activities compared to those wearing spectacles. They also perceive better peer acceptance and overall satisfaction with their vision correction.⁷ 
• Reversibility: If a child or family changes their mind, the cornea returns to its original shape over days to weeks.

One of the most helpful ways to simplify myopia management decision-making is to use a structured framework when discussing options with families. The best-performing interventions include myopia control spectacles (DIMS, HALT, DOT), dual-focus soft contact lenses, orthokeratology, and 0.05% atropine. These treatments have shown similar efficacy in slowing myopia progression based on randomized controlled trials with at least 12 months of data.8

When we’re deciding between different modalities, the choice may then come down to these considerations:

Best for: Younger children, or those who do not feel ready for contact lenses.

Considerations: Spectacles are easy to use but may not suit active children or those with high refractive errors. Frames may require frequent adjustments, and they are easy to remove, influencing compliance.

Best for: Active children, those seeking spectacles-free options, and/or families comfortable with contact lens handling.

Considerations: Compliance and hygiene are critical for best outcomes. Daily disposables are preferred for safety.⁹ 

Best for: Orthokeratology is best suited for children who prefer overnight lens wear and the freedom from optical correction during the day. It has shown efficacy for children with high myopia,¹⁰  those with moderate-to-high astigmatism¹¹  and myopic anisometropia.¹²  Orthokeratology is a great option for active children, especially those involved in sports such as swimming, where spectacles or daytime contact lenses may be less practical or contraindicated.

Considerations: Orthokeratology requires careful fitting and ongoing monitoring, which can be supported by digital tools and mobile applications that facilitate communication between the practitioner and patient. Good hygiene practices are essential to minimise infection risks.

Best for: Pre-myopes, or for myopes as an adjunct to other treatments.

Considerations: Atropine does not correct vision, so it must be combined with optical correction. Side effects like pupil dilation and near blur should be monitored.

For interventions that are perceived as more complex, such as orthokeratology, having a structured system in place can make a meaningful difference to both practitioner confidence and patient outcomes. This is particularly valuable for clinicians who are newer to orthokeratology or returning to it after some time, where reducing variability can help minimise decision fatigue and create a more predictable treatment pathway.

The Menicon Bloom system (pictured above) is one example of an integrated approach designed to support this process, combining practitioner facing tools with a patient app to facilitate communication and monitoring between visits. Patients and parents can provide regular feedback on their lens wearing experience, with this information feeding back to the practitioner to support ongoing care and identify potential issues early.

Structured systems allow for more consistent monitoring, clearer communication, and greater visibility of the patient experience outside of the consulting room. In this way, modalities that may initially seem more technique sensitive can become more manageable. Increased touchpoints between practitioner and patient (not just at follow-up appointments but through digital interfaces) can enhance engagement and support more responsive care.

For many practitioners, the challenge with orthokeratology might not be the fitting but the conversation. A helpful starting point is to shift the focus away from the modality itself and towards myopia as a progressive condition with long term implications. When parents understand that myopia is not just about needing stronger glasses but about future eye health risk, the purpose of treatment becomes clearer. From there, orthokeratology can be positioned simply and confidently:

Keeping the explanation straightforward helps avoid overwhelming families with technical detail. Most parents are not comparing optical designs, they are deciding what feels safe, practical, and right for their child.

Three communication principles can help guide the discussion:

1. Explain the clinical rationale: Begin by explaining the progressive nature of myopia and its long-term implications, before introducing management options.
2. Present orthokeratology as part of standard care: Position ortho-k alongside other established myopia management options, rather than as a specialised or last line treatment.
3. Tailor to the child’s needs: Relate the choice of treatment to the child’s visual demands, daily activities, and family preferences to support shared decision making.

Confidence in recommendation often comes down to clarity and consistency. When orthokeratology is presented as a routine and evidence-based option, families are better able to understand its role and feel comfortable moving forward.

Orthokeratology remains a well-established and effective option within the myopia management landscape, supported by a strong evidence base and distinct practical advantages. For practitioners who are new to ortho-k or returning to it after some time, confidence often comes from simplifying the process, focusing on key decision points, and using a structured approach to guide both clinical and communication steps. When combined with clear, consistent conversations that centre on long-term eye health and individual patient needs, ortho-k can be repositioned from a perceived complexity to a routine and valuable part of care.
