<p>The longitudinal evaluation of the dual treatment protocol combining orthokeratology (Ortho-K) lenses and 0.01% atropine eye drops focused on assessing tear film stability, corneal epithelial alterations, and visual function in pediatric myopia control.

摘要

The longitudinal evaluation of the dual treatment protocol combining orthokeratology (Ortho-K) lenses and 0.01% atropine eye drops focused on assessing tear film stability, corneal epithelial alterations, and visual function in pediatric myopia control. This prospective, randomized study enrolled 100 participants aged 8 to − 18 years, categorized into Group A (Ortho-K + 0.01% atropine) and Group B (Ortho-K monotherapy). The subjects were followed for 12 months, with assessments at 1, 3, 6, and 12 months. The key parameters analyzed included axial length progression, spherical equivalent refraction, best-corrected visual acuity (BCVA), corneal topography, corneal epithelial thickness, corneal endothelial cell density, intraocular pressure (IOP), tear break-up time (TBUT), Schirmer’s test results, and ocular surface integrity determined via fluorescein and lissamine green staining. Compared with Group B (Δ0.5 ± 0.07 mm, p < 0.05), Group A exhibited superior myopia control, with a significant reduction in axial elongation (Δ0.3 ± 0.05 mm, p = 0.04). BCVA improved more in Group A (-0.1 ± 0.04 LogMAR, p = 0.03) than in Group B (-0.15 ± 0.04 LogMAR, p < 0.05). However, tear film stability decreased in Group A, as evidenced by a greater reduction in TBUT (Δ1.5 ± 0.3 s, p = 0.04) than in Group B (Δ0.7 ± 0.2 s, p = 0.05). Corneal epithelial thinning was more pronounced in Group A (Δ2.5 ± 0.5 μm, p = 0.05) than in Group B (Δ1.0 ± 0.3 μm, p = 0.07). No significant differences in Schirmer’s test, endothelial cell density, or IOP were noted between the groups. Patient adherence was greater in Group A than in Group B (93% vs. 91%), and both groups reported high patient satisfaction scores. These findings suggested that dual therapy enhances myopia control while maintaining corneal and ocular surface integrity, although tear film stability and epithelial health require careful long-term monitoring. Further longitudinal studies with larger cohorts are necessary to confirm the long-term safety and efficacy of this combined approach.
