Myopia Control Using Novel Soft Contact Lenses
126 participantsStarted 2026-04-16
Plain-language summary
The goal of this study is to investigate the myopic control efficacy of two study soft contact lenses in children. Participants will be prescribed Lens A, Lens B or single vision contact lenses for the first year. Participants in single vision contact lenses group will switch to Lens A at 12 months. All participants will then continue lens wear for an additional 12 months. Their cycloplegic refraction and axial length will be monitored every 6 months for 2 years.

Inclusion Criteria:
* • Age at enrolment: 7 - 12 (both inclusive) years old Hong Kong Chinese schoolchildren
* Refractive errors in terms of spherical equivalent refraction (SER) determined by cycloplegic autorefraction: -0.75 diopters (D) to -5.00D in both eyes
* Astigmatism: equal or less than -1.00D
* Anisometropia: equal or less than -1.75D
* Previous myopia progression:
* -0.50D (in SER) per year or more in 1 eye or both eyes OR Axial length elongation: 0.27mm/year in 1 eye or both eyes
* If myopia is initially detected during screening, eligibility requires an SER below the 3rd percentile curve of refraction in either or both eyes (4)
* Best corrected visual acuity: better than 0.04 LogMAR in both eyes
* Ocular health: no abnormalities in both internal and external ocular health
* Systemic health: no systemic interference with ocular vision functioning
* Binocular vision: no strabismus and other binocular abnormalities
* No medication or supplements that affect eye growth
* Normal colour vision
* No previous use of myopic control interventions such as red-light therapy, atropine, orthokeratology, specialized spectacle lenses and contact lenses and oral supplements for myopic control
* Agree to maintain the visit schedule and be able to keep all appointments as specified in the informed assent and consent forms throughout study duration.
* Agree to accept either the control or study lens as assigned by the randomization scheme

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
