Effect of defocus incorporated multiple segments lenses on halting myopia progression not responding to low-concentration atropine (0.01%) eye drops

Abstract

To assess the effect of defocus incorporated multiple segments (DIMS) (Miyosmart) lenses on myopic progression in children not responding to low-concentration atropine (LCA) (0.01%) eye drops. A total of 10 children not responding to LCA (0.01%) eye drops were advised to start using the DIMS lens to halt the progression of myopia. The children were followed for a period of 1 year. Eight out of 10 children showed a reduction in the progression of myopia. Pre DIMS, the progression was −0.68 D ± 0.3 D sph, which reduced to −0.24 ± 0.2 diopter progression post DIMS lens in the eight children. The remaining two children still progressed by −0.57 ± 0.4 D sph over a year. The axial length growth reduced from 0.28 ± 0.3 mm to 0.16 ± 0.2 mm after using the DIMS lens in these non-responders. The DIMS lens shows initial promise in reducing the progression of myopia even in children not responding to LCA 0.01% eye drops.
