AIM:To investigate the effect of orthokeratology on stereopsis, accommodation parameters and ocular biological parameters in myopic patients.

METHODS: The clinical data of 65 patients(130 eyes)with myopia in our hospital from January 2016 to May 2017 were analyzed and they were divided into high myopia group, moderate myopia group and slight myopia group. The changes of stereopsis, accommodation parameters and ocular biological parameters were compared between the myopic patients before and after the operation.

RESULTS: The difference of distant vision, stereo acuity, accommodation range and accommodation sensitivity between the three groups were statistically significant(P<0.05). The uncorrected visual acuity, the degree of spherical equivalent and the diopter of cylindrical power in the myopic eyes were significantly lower than those before treatment, and the difference was statistically significant(P<0.05). The intraocular pressure and central corneal thickness were not different compared with before treatment(P>0.05). After treatment, the corneal curvature was lower and axial length were higher than those before treatment, the difference was statistically significant(P<0.05).

CONCLUSION: Orthokeratology can obviously improve the distance and near vision and stereoscopic vision function of myopic patients, which may slow the increase of axis and reduce the corneal curvature.
