Objective:

To evaluate the effectiveness of orthokeratology (OK) lenses for myopia control in a 9-year-old patient and explore alternative strategies such as low-dose atropine and soft multifocal lenses.

Key Findings:

• Marika's myopia progressed after switching to OK lenses despite good compliance, indicating potential issues with lens design or fit.
• Noncompliance with anti-myopia spectacles can lead to rapid myopia progression, emphasizing the need for consistent wear.
• Lens centration and the amount of myopic defocus delivered by OK lenses are critical for effective myopia management.
• A slightly decentered lens may provide a greater myopia control effect than a perfectly centered lens, challenging conventional assumptions.

Interpretation:

The findings suggest that while OK lenses can be effective for myopia control, individual factors such as lens design, compliance, and the specific characteristics of the patient's myopia must be carefully considered to optimize outcomes.

Limitations:

• The case study is based on a single patient, limiting generalizability to broader populations.
• Potential confounding factors such as genetic predisposition and environmental influences were not fully explored, which could affect the findings.

Conclusion:

An individualized approach to myopia management is essential, considering various factors influencing myopia progression and the effectiveness of different optical corrections, including the need for ongoing evaluation and adjustment.
