DIMS lenses offer long-term benefits in reducing myopia-related vision risks

Using Defocus Incorporated Multiple Segments (DIMS) lenses to control myopia progression in children is a cost-effective strategy, significantly reducing the risk of severe vision problems in adulthood, according to a study.

Myopia, projected to affect half of the global population by 2050, increases the risk of sight-threatening complications in adulthood. The study utilized a state-transition model to simulate the long-term outcomes of myopia control compared to no intervention, focusing on both myopia progression in childhood and its impact on adult vision health.

Implementing myopia control reduced the prevalence of high myopia by 44.7% and severe visual impairment by 19.2%. The lifetime cost per quality-adjusted life year gained was $26,407, falling below the World Health Organization’s cost-effectiveness threshold of one times per capita gross domestic product ($48,359 USD). Sensitivity analysis indicated an 87% likelihood of myopia control being cost-effective.
