High myopia control is comparable between multifocal rigid gas-permeable lenses and spectacles [PDF]

open access: yesFrontiers in Medicine, 2023
PurposeOcular pathology may be reduced by slowing myopia progression. The purpose of this study was to evaluate the potential of a novel custom-designed rigid gas permeable (RGP) contact lens to control high myopia by comparing the efficacy of multifocal
