Vincent SJ, Tan Q, Ng ALK, et al. - Researchers conducted the study for comparing the changes in higher-order aberrations (HOA’s) for photopic and mesopic pupil diameters in children undergoing orthokeratology treatment (OK) or combined 0.01% atropine with orthokeratology treatment (AOK) and their connection with axial elongation. Children aged 6 to < 11 years with 1.00–4.00 D of myopia have been randomly assigned to each treatment group. Using an optical biometer under cycloplegia, axial length was measured. Baseline and six‐month data from 25 AOK and 28 OK participants have been analyzed. According to findings, AOK therapy led to increased photopic pupil size and HOA’s, and significantly less axial elongation over a six‐month period compared with OK treatment alone. The improved myopia control observed with the combination of 0.01% atropine and orthokeratology which result from an enhanced optical effect due to larger photopic pupil size.
