Two year clinical study outcomes for the Defocus Incorporated Multiple Segments (DIMS) spectacle lens

This study reports two year results from a randomized clinical trial examining Defocus Incorporated Multiple Segments (DIMS) spectacle lenses for myopia control. The findings showed around 50% refractive and 60% axial length efficacy in Hong Kong Chinese children, with an absolute effect of 0.44D lower refraction and 0.34mm less axial elongation in DIMS wearers.

One-year myopia control efficacy of spectacle lenses with aspherical lenslets

This study reports one year results from an ongoing randomized clinical trial examining spectacle lenses with highly aspherical lenslet (HAL) or slightly aspherical lenslet (SAL) technology. The findings showed the HAL lens controlled refractive and axial progression by 60-70% and SAL by 30-40% over the first 12 months.
