Abstract
Objective To evaluate corneal epithelium damage in teenagers undergoing overnight orthokeratology treatment.Methods 201 teenagers(375 eyes) who accepted overnight orthokeratology treatment from September 2009 to December 2010 were observed.The relationship between the degree of myopia before treatment(-1.00——2.00 D,-2.25——4.00 D and-4.25——6.00 D),the occurrence time and the incidence rate of corneal epithelium damage after orthokeratology treatment were statistically analyzed.Results The incidence rate of corneal epithelium damage was 17.1%,31.4% and 42.4% in the three groups respectively,and the difference was significant(χ2=13.439 4,P=0.001).The occurrence time of the corneal epithelium damage among the three groups was also statistically significant(χ2=12.45,P=0.002).Conclusion Myopia degree is positively related with incidence rate and time of corneal epithelium damage.Therefore,earlier orthokeratology treatment should be given in order to get better control of myopia.
