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 This study
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
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 Results may not be published yet.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

Summary

This study tests whether special glasses called Kubota Glass can temporarily change the length of the eye, which is key to controlling nearsightedness (myopia). Participants aged 8 to 24 with mild to moderate myopia will try five different lens settings in a randomized, double-masked design. The goal is to find the best optical defocus parameters for slowing myopia progression.

What this could mean

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

Active substance
Kubota Glass (optical defocus device)
What this could lead to
If successful, this could lead to a non-invasive way to slow or control myopia progression in children and young adults.
What could go wrong
This is a small, early-stage study focused on temporary changes, not long-term outcomes. The effect may not translate to lasting myopia control.

Participants

About 35 people

The number the study aims to enrol. It can still change while the study runs.

Expected to start

Jul 2026

An estimate. Start dates often move.

Expected to finish

Dec 2026

Lead sponsor

A company

The lead sponsor is a pharmaceutical, biotech, or medical-device company.
