Abstract

Study design: prospective, interventional. Aim: to evaluate the effectiveness of prescribing DIMS spectacle lenses for myopia control over 1 year in patients in south India. Methodology: We had 55 patients, of whom 20 had 6-month follow-ups and 17 had 1-year follow-ups. Age: 6–16-year-old children. The range of myopia varied from -1.00 to -10 D. Myopia progression was defined as the increase in spherical equivalent dioptric power of ≥-0.50in the previous 6 months. Exclusion criteria: Non-progressors, New myopes, strabismus, and binocular abnormalities. Results: The average spherical equivalent before prescribing DIMS spectacle lenses was -0.95D ± 0.50D, and after 1 year of DIMS wear, was -0.20D ± 0.31D. The mean difference in axial length before DIMS was -0.39 mm, and after DIMS was -0.05 mm. Conclusion: DIMS spectacle lenses slowed refractive error progression by 78% and axial length by 87.2% over a period of one year. It can be an effective option in myopia control.
