WEDNESDAY, Aug. 12, 2020 (HealthDay News) — Among children with myopia, treatment with high add power multifocal contact lenses reduces the rate of myopia progression over three years compared with medium add power multifocal and single-vision contact lenses, according to a study published in the Aug. 11 issue of the Journal of the American Medical Association<\/i>.<\/p>\n
Jeffrey J. Walline, O.D., Ph.D., from The Ohio State University College of Optometry in Columbus, and colleagues randomly assigned 294 consecutive eligible children (aged 7 to 11 years) with spherical component myopia to wear high add power (+2.5 D; 98 children), medium add power (+1.5 D; 98 children), or single-vision (98 children) contact lenses.<\/p>\n
The researchers found that adjusted three-year myopia progression was \u22120.60 D for high add power, \u22120.89 D for medium add power, and \u22121.05 D for single-vision contact lenses, with differences in progression of 0.46 D for high add power versus single-vision contact lenses, 0.30 D for high add versus medium add power contact lenses, and 0.16 D for medium add power versus single-vision contact lenses. Of the four secondary end points, there were no statistically significant differences between the groups for three of the end points. Three-year adjusted mean eye growth was 0.42 mm for high add power, 0.58 mm for medium add power, and 0.66 mm for single-vision contact lenses, with differences in eye growth of \u22120.23 mm for high add power versus single-vision contact lenses, \u22120.16 mm for high add versus medium add power contact lenses, and \u22120.07 mm for medium add power versus single-vision contact lenses.<\/p>\n
“Further research is needed to understand the clinical importance of the observed differences,” the authors write.<\/p>\n
Several authors disclosed financial ties to Bausch + Lomb, which provided contact lens solutions for the study.<\/p>\n
