Tests treatment safety and results for Myopia
Official title Efficacy in Controlling Myopia in Young Children Using a Novel Spectacle Lens
ClinicalTrials.gov ID: NCT06034327
What this study is testing
- What it's testing
- This is a conventional efficacy trial to validate the results from previous clinical trials for younger children; the 12-month efficacy results will be used to predict the 3-year treatment efficacy. This is a randomized, controlled (1:1), multisite, subject- and observer-masked, 2-arm parallel group study.

Who can take part
Ages 6 to 8. Healthy volunteers may be eligible.
You may be able to join if
- Children 6 - 8 years of age (inclusive) at time of informed consent/assent;
- Spherical equivalent refractive error between -0.75 and -4.50 D inclusive (by manifest refraction) in each eye;
- Astigmatism if present, less than or equal to -1.25 DC (by manifest refraction) in each eye;
- Best corrected visual acuity by manifest refraction of +0.10 logMAR (20/25 Snellen equivalent) or better in each eye;
- The difference in spherical equivalent power between the two eyes (anisometropia based on manifest refraction) must be less than or equal to 1.50 D;
You likely can't join if
- Subject has previously or currently wears contact lenses (greater than 1-month usage);
- Current or prior use of bifocals, progressive addition spectacle lenses
- Current or prior use of any myopia control treatment (e.g., atropine, multifocal contact lenses, orthokeratology);
- Amblyopia in either eye;
- Strabismus by cover test at far (4 m) or near (40 cm) wearing distance correction;
- Any ocular or systemic conditions that could influence refractive development or status [e.g., keratoconus, congenital glaucoma, ocular trauma...
