- Willing to undergo treatment to slow myopia progression for one year
Who cannot join

About this study
Official title: Multicenter Study of Near Vision Behavior and Outdoor Time in Children Undergoing Myopia Control
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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
ViviorDevice
The Vivior is a wearable clip-on sensor that objectively quantifies near viewing distance and duration, and ambient illumination. The Vivior will be attached to the spectacles frame of children undergoing myopia control treatment.
What is being measured
The primary outcome is the main question the study is designed to answer.
Near viewing duration
Duration during near tasks
Measured: 12 months
Near viewing distance
Distance during near tasks
Measured: 12 months
Outdoor time
Ambient illumination to determine time spent outdoors
Measured: 12 months
Secondary outcomes (3)

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does the primary outcome measure?
Near viewing duration (time frame: 12 months). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
