SIGNIFICANCE: Combining 0.01% atropine with soft multifocal contact lenses (SMCLs) failed to demonstrate better myopia control than SMCLs alone.
PURPOSE: The Bifocal & Atropine in Myopia (BAM) Study investigated whether combining 0.01% atropine and SMCLs with +2.50-D add power leads to greater slowing of myopia progression and axial elongation than SMCLs alone.
METHODS: Participants of the BAM Study wore SMCLs with +2.50-D add power daily and administered 0.01% atropine eye drops nightly (n = 46). The BAM subjects (bifocal-atropine) were age-matched to 46 participants in the Bifocal Lenses in Nearsighted Kids Study who wore SMCLs with +2.50-D add power (bifocal) and 46 Bifocal Lenses in Nearsighted Kids participants who wore single-vision contact lenses (single vision). The primary outcome was the 3-year change in spherical equivalent refractive error determined by cycloplegic autorefraction, and the 3-year change in axial elongation was also evaluated.
RESULTS: Of the total 138 subjects, the mean ± standard deviation age was 10.1 ± 1.2 years, and the mean ± standard deviation spherical equivalent was -2.28 ± 0.89 D. The 3-year adjusted mean myopia progression was -0.52 D for bifocal-atropine, -0.55 D for bifocal, and -1.09 D for single vision. The difference in myopia progression was 0.03 D (95% confidence interval [CI], -0.14 to 0.21 D) for bifocal-atropine versus bifocal and 0.57 D (95% CI, 0.38 to 0.77 D) for bifocal-atropine versus single vision. The 3-year adjusted axial elongation was 0.31 mm for bifocal-atropine, 0.39 mm for bifocal, and 0.68 mm for single vision. The difference in axial elongation was -0.08 mm (95% CI, -0.16 to 0.002 mm) for bifocal-atropine versus bifocal and -0.37 mm (95% CI, -0.46 to -0.28 mm) for bifocal-atropine versus single vision.
CONCLUSIONS: Adding 0.01% atropine to SMCLs with +2.50-D add power failed to demonstrate better myopia control than SMCLs alone.
