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 Results may not be published yet.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

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This status has not been confirmed recently, so it may be out of date.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 compares two types of special glasses (DIMS and DOT) to control nearsightedness in children aged 6 to 12 who also have intermittent exotropia (a type of eye misalignment). Researchers want to see which lens works better and whether the glasses affect eye coordination. The study involves 120 children and will measure changes in eye length and vision over time.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 120 people

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

Expected to start

Jun 2026

An estimate. Start dates often move.

Expected to finish

May 2027

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

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

Inclusion Criteria: 1. Participants aged 6 to 12 years (6 ≤ age ≤ 12 years). Written informed consent from legal guardians is mandatory. 2. Patients with basic-type intermittent exotropia (IXT) meeting all the following criteria: 1. Intermittent or constant exotropia at the distance of 6 meters, and intermittent exotropia or esophoria at the near distance of 33 centimeters; 2. Distance exodeviation ≥ 10 prism diopters (PD) measured via the prism and alternate cover test (PACT); 3. The difference between near and distance deviation ≤ 10 PD. 3. Based on cycloplegic spherical equivalent (SE), the myopic refractive error of both eyes ranges from -6.0 D to -0.5 D. 4. The logMAR value of monocular distance best-corrected visual acuity (BCVA) measured by the ETDRS chart is ≤ 0.2, and no amblyopia is present. 5. Parents and children are willing to participate in this clinical trial and can complete the entire study protocol. 6. Children have healthy eyes without organic ocular diseases. Exclusion Criteria: 1. Participants who have worn myopia control glasses or received other myopia interventions, including low-concentration atropine and phototherapy instruments, within the past 6 months (excluding DIMS and DOT glasses). 2. Those with severe systemic diseases or cognitive impairment that hinders follow-up attendance and clinical examinations. 4\. Subjects with astigmatism of ≥ 2 diopters (D) in either eye after cycloplegia; individuals enrolled in other interventional trials. 5\. Patients with active ocular inflammation in either eye. 6. Those diagnosed with ocular diseases or presenting with clinically significant abnormalities on ophthalmic examinations. 7\. Participants are currently receiving visual function training or other clinical interventions for intermittent exotropia. 8\. Individuals who decline to complete the 1-year follow-up period.
