- The study investigated how first-year axial elongation predicts 10-year myopia progression in children wearing orthokeratology lenses.
- Analysis of 101 children over 10 years identified baseline AL, first-year AL change (Chang AL), and flat eccentricity as predictors for AL > 26 mm after 10 years.
- A predictive model for 10-year AL > 26 mm achieved an AUC of 0.952, while first-year AL change alone predicted rapid progression in years 9-10 with an AUC of 0.995.
- The optimal first-year AL change cutoff for stable long-term progression was 0.28 mm overall, with age-specific cutoffs of 0.28 mm for ages 8-9 and 0.29 mm for ages 10-13.
- Findings suggest first-year treatment response is a key indicator for long-term myopia control, with monitoring of the 0.28 mm threshold enabling early identification of at-risk children.
