A Comparison of the Effects of Orthokeratology Lens, Medcall Lens, and Ordinary Frame Glasses on the Accommodative Response in Myopic Children
To observe and compare changes in accommodative response between myopic children wearing ordinary frame glasses (OFG), Mouldway orthokeratology lenses (M-OK), and medcall lenses (ML).Methods:
A total of 240 myopic children were divided into three groups: OFG [n=90]; M-OK [n=90]; and ML [n=60]). The diopter, accommodative lag, and binocular accommodative facility before wearing glasses (T0) and 1-year after wearing glasses (T1) were compared among the three groups.Results:
Commercially available software was used to perform statistical analysis, and the data were expressed as mean±SD. There were no significant differences among the three groups at T0. The accommodative lags in M-OK and ML at T1 were significantly lower than those at T0; this finding was most evident in M-OK. Although accommodative facility increased in all three groups, the increase was most evident in M-OK and ML.Conclusion:
Mouldway orthokeratology lenses and ML can reduce the accommodative lag and increase the accommodative facility in myopic children. Compared with ML, M-OK showed considerably more marked effects to myopia progression in children.
