What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 D.I.M.S. glasses, which have special lenslets that create blur in the peripheral vision, can slow the progression of myopia (nearsightedness) in children aged 6 to 15. Participants wear the glasses while awake and visit the clinic every six months for eye exams and measurements of eye length. The researchers also track time spent outdoors and screen time to see if these factors affect 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
D.I.M.S. (Defocus Incorporated Multiple Segments) glasses
What this could lead to
If successful, this could provide a non-invasive way to slow myopia progression in children, reducing the need for stronger prescriptions and lowering the risk of severe eye problems later in life.
What could go wrong
This is a small observational study, not a randomized trial, so results may not apply to all children. The glasses may not work for everyone, and long-term effects are still being studied.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

Participants (between 6 and 15 years of age) are wearing myopia progression treatment , namely D.I.M.S. lenses while they are awake. The wear these glasses to correct refractive error and to slow down myopia progression. At enrollment the refractive error measured under cycloplegia, expressed as spherical equivalent must be: between -0.50 Dsph and -10.0 Dsph.

Ages

6 to 15 years

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Inclusion Criteria: * • Participants must be between 6 and 15 years of age at the start of myopia progression treatment * Caucasian ethnicity * Refractive error measured under cycloplegia, expressed as spherical equivalent: between -0.50 Dsph and -10.0 Dsph * Wearing myopia-control glasses while awake * Participation in follow-up examinations every 6 months Exclusion Criteria: * • Pathological myopia (e.g., myopia onset before age 6, Stickler syndrome) * Premature birth before the 32nd week of gestation * Previous eye-opening surgery (e.g., lens removal) * Traumatic eye injury * Known connective tissue disorder (e.g., Marfan syndrome) * Irregular or improper use of progressive-lens glasses * Failure to attend the follow-up examinations scheduled every 6 months
