Changes of corneal biomechanics in children using orthokeratology and their roles in predicting axial length progression-A prospective 2-year study.

Corneal biomechanics firstly fluctuated before becoming stable with long-term ortho-k use. Corneal biomechanics was associated with AL progression in children wearing ortho-k lenses. DA combined with age and AL at baseline could predict AL progression in low myopes using ortho-k.
