Abstract<\/h2>

Aim<\/h3>

To determine if \u2018Defocus Incorporated Multiple Segments\u2019 (DIMS) spectacle lenses slow childhood myopia progression.<\/p><\/div>

Methods<\/h3>

A 2-year double-masked randomised controlled trial was carried out in 183 Chinese children aged 8\u201313 years, with myopia between \u22121.00 and \u22125.00 D and astigmatism \u22641.50 D. Children were randomly assigned to wear DIMS (n=93) or single vision (SV) spectacle lenses (n=90). DIMS lens incorporated multiple segments with myopic defocus of +3.50 D. Refractive error (cycloplegic autorefraction) and axial length were measured at 6month intervals.<\/p><\/div>

Results<\/h3>

160 children completed the study, n=79 in the DIMS group and n=81 in the SV group. Average (SE) myopic progressions over 2 years were \u22120.41\u00b10.06 D in the DIMS group and \u22120.85\u00b10.08 D in the SV group. Mean (SE) axial elongation was 0.21\u00b10.02\u2009mm and 0.55\u00b10.02\u2009mm in the DIMS and SV groups, respectively. Myopia progressed 52% more slowly for children in the DIMS group compared with those in the SV group (mean difference \u22120.44\u00b10.09 D, 95%\u2009CI \u22120.73 to \u22120.37, p<0.0001). Likewise, children in the DIMS group had less axial elongation by 62% than those in the SV group (mean difference 0.34\u00b10.04\u2009mm, 95%\u2009CI 0.22 to 0.37, p<0.0001). 21.5% children who wore DIMS lenses had no myopia progression over 2 years, but only 7.4% for those who wore SV lenses.<\/p><\/div>

Conclusions<\/h3>

Daily wear of the DIMS lens significantly retarded myopia progression and axial elongation in myopic children. Our results demonstrated simultaneous clear vision with constant myopic defocus can slow myopia progression.<\/p><\/div>
