Multifocal spectacles in childhood myopia: Are treatment effects maintained? A systematic review and meta-analysis.

We evaluate the impact of duration on the treatment effect of multifocal spectacle lenses used to inhibit myopia progression in children. A systematic literature search identified randomized controlled trials where multifocal lenses were prescribed as the intervention, with single vision lenses as the control. Nine randomized control trials involving 1701 children aged eight to 13 years, were included in the meta-analysis. Treatment effects, i.e. differences in spherical equivalent refraction between intervention and non-intervention groups, were analyzed over both six- and 12-month intervals.
