This randomized controlled trial evaluated the impact of extended depth-of-focus (EDOF) soft contact lenses on myopia control in 60 Japanese children aged 6 to 12 years. The study found that Mid-EDOF lenses significantly suppressed axial elongation and spherical equivalent progression by 49% and 59%, respectively, compared to single-vision lenses over 12 months.
Key findings
- Mid-EDOF lenses suppressed axial elongation by 49% compared to single-vision lenses.
- Mid-EDOF lenses reduced spherical equivalent progression by 59% compared to controls.
- Low-EDOF lenses showed no significant effect on axial elongation or spherical equivalent progression.
- Visual function changes included reduced contrast sensitivity and increased higher-order aberrations in the Mid-EDOF group.
Why it matters
Understanding the efficacy of different optical profiles in EDOF lenses can guide clinicians in selecting appropriate myopia control strategies for children, potentially reducing the long-term risk of myopia-related complications.
