Objective: To investigate the effect of wearing dual-focus soft contact lenses (DFSCL) on the visual performance of school-age children.
Methods: In this randomized controlled clinical trial, 64 children aged 8 to 12 years with spherical equivalent refraction between -0.75 D and -4.
Article Synopsis
- * The study involved 64 children, with follow-up over 12 months measuring axial length growth and spherical equivalent refraction; results showed that the DFSCL group had less axial length growth than the SVS group (0.23 mm vs. 0.33 mm).
- * While DFSCL helped reduce growth in axial length in the initial months, no significant advantages were found in spherical equivalent refraction changes, and children reported issues like blurriness and discomfort with prolonged wear.
Purpose: The aim of this study was to investigate the effect of individualized ocular refraction customized (IORC) spectacle lenses with different actual amounts of peripheral myopic defocus (MD) on myopia control over 1 year. These lenses compensate for the original peripheral refraction via the free-form surface on the back of the lens.
Methods: This 1-year, double-masked randomised clinical trial included 184 myopic schoolchildren aged 8-12 years.
Purpose: Individualized ocular refraction customization (IORC) lenses can be individually adjusted depending on the initial relative peripheral refraction to determine the myopic defocus (MD). We aimed to compare visual performance of children wearing IORC lenses with different amounts of MD to determine whether higher MD resulted in greater visual compromise.
Methods: This study included 184 myopic children aged eight to 12 years, and 172 completed the trial.
