About this trial

Currently, optical and pharmacological interventions have been developed to prevent the progression of childhood myopia. However, no myopia control strategy has been shown to have complete efficacy in controlling myopia progression in children. One possible reason is that risk factors contributing to the development of myopia were not controlled in previous clinical studies including time outdoors and near vision behaviour. This study aims to quantify time spent outdoors and near vision behavior in myopic children and its impact on myopia control efficacy. The outcomes of this study will guide clinicians on risk management and improve responses to existing treatments for progressive myopia.

Eligibility criteria

Qualifiers

Aged 6 to below 14 years old

Spherical equivalent myopic refractive error greater than -0.50 D

Best corrected logMAR visual acuity of 0.1 or better in each eye for 6- to 14-year-old children, and 0.2 logMAR or better than in each eye for 4 and 5-year-old children (adjusted for age-related expectations)

Good ocular and general health that would not preclude them from myopia control

Disqualifiers

Strabismus at distance or near, or amblyopia

Systemic or ocular conditions that may affect contact lens use (e.g. severe allergy) or refractive development (e.g. ptosis)

Previous history of ocular surgery, trauma or chronic ocular disease that may affect their vision

Ocular or systemic medication use which may interfere or interact with myopia treatment or ocular development
