A Multi-center Study of the Effect of Orthokeratology on Myopia Progression

A Prospective, Multi-center Study of the Effect of Orthokeratology on Myopia Progression in Chinese Children

This is a prospective study to validate an algorithm for predicting the effect of orthokeratology on myopia progression in children from 8 hospitals in China.

Orthokeratology (ortho-K) is thought to be an effective way to control the progression of Myopia in children, but its effectiveness may vary among different individuals. The investigators therefore conducted a prospective, multi-center study to use an algorithm to predict the progression of myopia among Chinese children wearing Orthokeratology lenses.

Inclusion Criteria:

• -6.0D≤SER≤-0.5D
• Astigmatism≤2.0D

Exclusion Criteria:

• Contraindications of wearing Ortho-K.
• Diagnosis of strabismus, amblyopia and other refractive development of the eye or systemic diseases.
• Currently involved in other clinical studies.
