Objective:
To explore the optimization of orthokeratology lens parameters for myopia control in young, low-myopic children.
Key Findings:
- Younger low-myopic patients show less axial length control with ortho-k compared to older children.
- Reducing BOZD can help shift midperipheral steepening into the pupil area for better myopic defocus.
- Higher baseline myopia, smaller BOZD, and larger pupil sizes correlate with improved myopia control.
Interpretation:
Managing myopia progression in low myopes using ortho-k is complex and may require additional treatments like low-dose atropine.
Limitations:
- Reduced BOZD alone may not provide sufficient myopia control for low myopes due to modest corneal shape changes.
- Mixed evidence exists regarding the effectiveness of increasing the compression factor.
Conclusion:
Combining reduced BOZD with other therapies may enhance myopia management in young low-myopic patients.
