Key Takeaways
- Children who switched to a different myopia-control spectacle type showed a significant reduction in myopia progression after the change.
- Before switching, the change-of-type group experienced faster myopia progression than children who continued using the same spectacle type.
- The benefit of switching was not sustained, as myopia progression accelerated again with prolonged use of the new spectacles.
Children with myopia who switched to a different type of myopia-control spectacle experienced a temporary slowing of myopia progression, according to a study.
The retrospective matched-cohort study 1,012 children and adolescents prescribed myopia-control spectacles. Researchers compared 253 participants who switched to a different spectacle type with 759 who continued using the same type after propensity score matching.
Before the switch, children in the change-of-type group had significantly faster myopia progression than those who maintained the same spectacle type. After switching, the progression rate in the change-of-type group slowed significantly, reducing the difference in progression rates between the groups.
However, the benefit was not maintained over time. Researchers found that myopia progression accelerated again during prolonged use of the new spectacle type, with progression rates worsening in the later phase compared with the early phase after switching.
