| Outline of Final Research Achievements |
Myopia progression in children is driven largely by axial length elongation. We investigated the additive effects of orthokeratology (OK) and atropine 0.01% ophthalmic solution in slowing axial elongation. Boys and girls aged 8 to 12 years with a spherical equivalent refractive error (SER) of -1.00 to -6.00 dioptres (D) were randomly allocated into two groups to receive either the combination of OK and atropine 0.01% ophthalmic solution (combination group), or monotherapy with OK (monotherapy group). The combination group suppressed significantly axial elongation over 1 year but not over 2 years compared to the monotherapy group. However, in the subgroup of subjects with a SER of -1.00 to -3.00 D, axial elongation over 2 year was significantly suppressed by the combination group compared to the monotherapy group. The combination of OK and atropine 0.01% ophthalmic solution was more effective than monotherapy with OK in children with lower myopia, especially during the first year.
