The purpose of the current study is to evaluate whether the DISC3.5 Plus contact lens will slow myopia progression and axial length growth in myopic children as compared with single vision soft contact lenses.~The Defocus Incorporated Soft 3.5 Plus Contact Lens (DISC3.5 Plus) is a soft contact lens that comprises of simultaneous distance optical prescription and myopic defocus areas.~The efficacy of the DISC3.5 Plus lens in slowing myopia progression (change in refractive error) will be compared to a spherical (front and back surface) single vision soft contact lenses in this one-year prospective, randomised and double-masked clinical trial. The hypothesis of this study is that the DISC3.5 Plus will slow myopia progression more than spherical single vision soft contact lenses.
The aims of the study is to evaluate whether the DISC3.5 Plus contact lens will slow myopia progression and axial length growth in myopic children as compared with single vision soft contact lenses.
