Abstract:
Objective To compare the efficacy and safety of defocus incorporated soft contact lenses(DISC)and orthokeratology(Ortho-K)for myopia control in children aged 8～15 years,and to further investigate the influence of dif-ferent baseline age and spherical equivalent(SE)on the treatment effect.Methods A retrospective cohort study was conducted,involving 197 myopic children(197 eyes)aged 8～15 years who were fitted with contact lenses at the Depart-ment of Ophthalmology,Xi'an People's Hospital(Xi'an Fourth Hospital)from May to September 2023.They were divid-ed into the DISC group(97 cases)and the Ortho-K group(100 cases).After 12 months of continuous follow-up,the chan-ges in axial length(AL)at 3,6,and 12 months after lens wear were compared between the two groups.Subgroup analysis was then performed:participants were divided into a younger subgroup(8～10 years)and an older subgroup(11～15 years)based on pre-wear age,and into a low myopia subgroup(-1.00～-3.00 D)and a moderate myopia subgroup(-3.25～-6.00 D)based on pre-wear SE.The AL changes at 3,6,and 12 months after wearing DISC or Ortho-K were com-pared between groups within these subgroups.Meanwhile,the incidence of conjunctivitis,incidence of corneal staining,corneal endothelial cell density,and corneal thickness were compared between the two groups at 12 months after lens wear.Results Inter-group comparisons showed:The change in AL in the DISC group at 3 months after lens wear was significantly lower than that in the Ortho-K group,and the difference was statistically significant(P＜0.05);at 6 and 12 months after lens wear,the differences in AL change between the two groups were not statistically significant(both P＞0.05).Subgroup analysis by age and SE showed:In the younger subgroup and the low myopia subgroup,the AL change in the DISC group at 3 months after lens wear was significantly lower than that in the Ortho-K group,and the differences were statistically significant(both P＜0.05),but these differences disappeared at 6 and 12 months after lens wear(all P＞0.05);in the older subgroup and the moderate myopia subgroup,the differences in AL change between the two groups at 3,6,and 12 months after lens wear were not statistically significant(all P＞0.05).At 12 months after lens wear,there were no statistically significant differences in the incidence of conjunctivitis,incidence of corneal staining,corneal endothe-lial cell density,or corneal thickness between the DISC and Ortho-K groups(all P＞0.05).Conclusion DISC demon-strates superior myopia control efficacy in the short term(3 months)for younger children and those with low myopia,but its medium-term(6 months)and long-term(12 months)efficacy converges with that of Ortho-K.Furthermore,the long-term safety of DISC is not significantly different from that of Ortho-K.
