What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tests whether progressive addition lenses (PALs), like bifocals without a visible line, can slow the progression of low myopia (nearsightedness) in children who have certain focusing traits. About 118 children with low myopia and specific vision characteristics were randomly assigned to wear either PALs or standard single vision lenses for three years. The goal is to see if the special lenses reduce how much their eyesight worsens over time.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Progressive addition lenses (PALs) with a +2.00 D addition
What this could lead to
If effective, these special glasses could offer a simple, non-invasive way to slow worsening nearsightedness in children, potentially reducing the need for stronger prescriptions later.
What could go wrong
This is a Phase 3 trial, but results may not apply to all children with myopia. The benefit, if any, might be small, and the special lenses are more expensive than standard glasses.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Refractive error determined by cycloplegic autorefraction which meets all of the following: 1. Spherical equivalent: -0.50 to -3.00 D in both eyes 2. Astigmatism \<= 1.5 D in both eyes 3. Anisometropia \<= 1.00 D difference between eyes in spherical equivalent * Visual acuity is at least 20/20 with best subjective refraction in both eyes * Accommodative response at near (33 cm) is less than 2.0D by non-cycloplegic autorefraction * Near esophoria (\>= 2.0 PD) present by alternate prism and cover test (APCT) at near using best refractive correction determined from non-cycloplegic subjective refraction Exclusion Criteria: * Strabismus present by cover-uncover test at far, near, and/or near with +2.00D over best subjective refraction * Current or prior use of PALs, bifocals, or contact lenses in either eye (prior or current use of SVLs is allowed)
