ClinConnect Summary

This clinical trial, called the MADRID study, is looking at how effective a combination of special contact lenses, known as orthokeratology (OK) lenses, and low-level red-light therapy can be in slowing down the worsening of nearsightedness, or myopia, in children who haven’t responded well to OK lenses alone. The study is taking place in Madrid, Spain, and is focused on children aged 8 to 15 years who have certain levels of myopia and have been struggling with rapid progression of their vision problems.

To participate, children need to have a specific range of nearsightedness and a clear vision of 20/20 or better in both eyes. They should also be willing to attend follow-up appointments and have permission from a parent or guardian. Participants will be divided into two groups: one will wear only the OK lenses, while the other will wear the lenses and receive the red-light therapy. Throughout the study, the children will have regular eye exams to monitor their eye growth. This research is fully funded by the institution and follows strict safety and ethical guidelines.
