Astigmatism and maternal myopia as important factors affecting success rate of DIMS lens treatment

AI Generated Summary*

Sixty-two Hungarian children aged 4 to 17 with prior myopia progression (mean baseline spherical equivalent -3.7 D, range about -0.9 to -8.3 D; astigmatism up to -3.25 D) wore defocus incorporated multiple segments (DIMS) spectacles for a year, reviewed retrospectively. Mean cycloplegic spherical equivalent change at 12 months was -0.40 D, and half met the no-progression threshold; axial length rose 0.16 mm among the 33 measured. Baseline astigmatism accompanied greater refractive (-0.49 vs -0.26 D) and axial (0.20 vs 0.12 mm) change, under-10s kept progressing past 6 months, and severe maternal myopia showed a borderline association (p=0.053). Baseline refraction did not predict outcome. Among 187 German single-vision wearers, astigmatism was unrelated to axial growth. Questionnaires suggested good tolerance.
