Abstract:
Objective:To compare the effect of different orthokeratology lenses in controlling the progression of low myopia in children, and to provide a reference for exploring effective prevention measures for eyesight of children.
Methods:A total of 175 cases (350 eyes) aged 8-12 years old who were fitted with orthokeratology lenses were collected in this retrospective study. The differences in the changes of the axis length (AL) and the spherical equivalent refraction (SER) were analyzed after wearing different orthokeratology lenses for one year, and the relationship between the change of AL, SER and gender, age was also analyzed.
Results:In the Mouldway group, Alpha group, Lucid group and CRT group, the Median ( P 25 , P 75 ) of AL changes were 0.23 ( 0.12 , 0.41), 0.30 (0.17, 0.45), 0.35 (0.16, 0.41) and 0.33 (0.23, 0.41)mm, and there were no statistical significant difference between four groups ( Z =7.70, P >0.05); The Median ( P 25 , P 75 ) of SER changes were -0.31 (-1.00, 0.28), -0.38 ( -1.22 , 0.13), -0.25 (-0.84, 0.13) and -0.63 (-1.13, 0.25)D, and there were no statistical significant difference between four groups ( Z =2.15, P >0.05). The age had negative correlation with the change of AL ( r =-0.26, P <0.05), but has nothing to do with the change of SER ( r =0.10, P >0.05). There was no statistically significant difference in the change of AL ( Z =2.25, P > 0.05 ) and SER ( Z =-1.50, P >0.05) among children of different genders.
Conclusion:Different orthokeratology lenses have no differences in controlling the growth of the AL and changing the SER.
