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

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.

Summary

This study tested whether special glasses (DIMS) are as good as overnight contact lenses (Ortho-K) at slowing myopia progression in children aged 6-12. Ninety kids wore either the glasses or the lenses for 18 months. The main goal was to see if the glasses were not worse than the lenses at controlling eye growth.

What this could mean

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

Active substance
DIMS spectacles and Ortho-K contact lenses
What this could lead to
If successful, this could show that DIMS spectacles are as good as Ortho-K lenses at slowing myopia progression, offering a non-contact alternative for children.
What could go wrong
This is a small, completed trial with 90 children. Results may not apply to all kids, and both treatments have risks like eye infections or discomfort.
