Abstract

Objective To investigate the effects of orthokeratology lenses and frame glasses on anisometropia in children with low myopia in one eye. Methods Between January 2017 and January 2018, 120 children of primary and secondary school age with myopic anisometropia low myopia in one eye presenting to the Second People's Hospital of Yunnan Province were selected as research objects, with average refractive error of(-1.00, -2.50)D in one eye and(-0.50, 0.50)D in another eye. Participants were divided into an experimental group and a control group (60 cases per group), according to a random number grouping method. The control group were given frame glasses, while the experimental group were given orthokeratology lenses. A prospective study was conducted to compare and analyze the lengths of the posterior eye axis (AL) and spherical equivalent (SE), measured at different time intervals between the two groups. Results There were some initial differences in AL and SE between the two groups before the experiment began; however, this difference was not statistically significant (P>0.05). After 12 months, participants myopic eyes given the orthokeratology lenses had shorter AL[(24.91±0.11)mm] compared to the control group[(25.02±0.09)mm], participants health eyes had longer AL[(24.58±0.24)mm] compared to the control group[(24.20±0.13)mm]. One month after the subjects stopped wearing plastic mirrors, participants myopic eyes had higher SE[(-2.22±0.78)D] compared to the control group[(-2.64±0.21)D], and had lower that in the control group[(-0.96±0.84)(-0.37±0.54)D](t=4.02, -4.58, P < 0.05). Conclusion In children with low myopia in one eye, compared with wearers of frame glasses, wearing corneal shape lenses can effectively restrain AL-extend and control the progression of eye myopia. At the same time, wearing corneal shape lenses can promote contralateral healthy-eye axial extension and an increase in diopter, reduce the anisometropia value, solve the problems of a binocular visual axis development imbalance, and promote coordinated eye development.
