Clinical Report: Optimizing Treatment in Low Myopes

Overview

Adjusting orthokeratology lens parameters can enhance myopia control in young, low-myopic children. Reducing the back optical zone diameter (BOZD) may improve outcomes, but additional strategies may be necessary for optimal management.

Background

Myopia management is crucial as the prevalence of myopia increases globally, particularly among children. Effective strategies are needed to control myopia progression and prevent associated complications. Orthokeratology (ortho-k) is a popular option, but its efficacy varies based on the degree of myopia and age of the patient.

Data Highlights

No numerical data available in the article.

Key Findings

• Lower axial length control is observed in young, low-myopic children using ortho-k lenses.
• Myopic defocus created by ortho-k lenses reduces the stimulus for axial length increase.
• Reducing BOZD can enhance myopic defocus but may not be sufficient alone for low myopes.
• Higher baseline myopia and larger pupil sizes correlate with improved myopia control using ortho-k.
• Combination therapy with low-dose atropine may be necessary for effective myopia management in low myopes.

Clinical Implications

Practitioners should consider adjusting the BOZD in ortho-k lenses for low myopes to enhance myopia control. Additionally, combining ortho-k with low-dose atropine may provide a more effective treatment strategy for managing myopia progression in this patient group.

Conclusion

Optimizing ortho-k treatment parameters is essential for managing low myopia in children. A multifaceted approach, including potential combination therapies, may yield better outcomes.
