Objective:

To analyze the one-year myopia control effects of corneal refractive therapy (CRT) lenses with different optical zone designs, specifically focusing on small optical zones, in children with varying degrees of baseline myopia.

Approach:

Key Findings:

• Small optical zones (5 mm, 5.5 mm) showed significant advantages in suppressing axial length elongation, indicating a potential for better myopia management.
• The effectiveness of OK lenses varied based on the severity of myopia and individual corneal morphology, suggesting the need for tailored approaches.

Interpretation:

The study highlights the importance of individualized fitting of OK lenses, which can enhance myopia control efficacy by considering patient-specific factors.

Limitations:

• Non-random grouping of participants may introduce selection bias, potentially affecting the validity of the findings.
• Exclusion of children with prior myopia control measures limits generalizability of the results.

Conclusion:

The findings provide clinical data to support myopia control strategies using CRT lenses with varying optical zone designs, emphasizing their relevance in addressing the public health issue of myopia.
