AIM: To observe the effectiveness and safety of orthokeratology in juvenile myopia patients.

METHODS: There were 204 eyes of 102 myopic patients, whose average diopter was -3.36±1.07D(spherical equivalent). The changes of mean myopia diopter, uncorrected visual acuity(UCVA), axial length, corneal thickness, visual quality and complications during two years of receiving orthokeratology treatment by the way of clinical diagnosis, general examination, slit lamp examination and corneal thickness examination were observed.

RESULTS: After receiving orthokeratology treatment for half a year, one year and two years, the naked vision and the mean myopia diopter had significant difference(P<0.05), the mean myopia diopter of all patients were decreased, and their naked vision were improve. There was no significant difference in corneal thickness and axial length(P>0.05). The corneal of patients were in good health. Discomfort symptoms due to wearing glasses can disappear after reasonable medication and adjustments with the glasses lenses.

CONCLUSION: Orthokeratology is a kind of method of effectively correcting eyesight and controlling growth of myopia. In the premise of security products, standard processes, qualified fitting technology and rigorous review, Long-term wearing orthokeratology lens is safe.
