Abstract:
Objective To observe the effect and safety of orthokeratology in myopia patients.Methods Sixty-eight(136 eyes)young patients with myopia wore orthokeratology lens as research group,and 55 cases(110 eyes)young patients with myopia wore glasses as control group,clinical data of both groups were retrospectively analyzed to evaluate the role of orthokeratology lens on controlling the progression of myopia.Results After treatment,uncorrected visual acuity of research group significantly improved (0.76 ± 0.15 vs.0.40 ± 0.13,P < 0.05),while spherical equivalent(SE)and corneal curvature significantly reduced[(-2.63 ± 1.06)D vs.(-3.52 ± 1.25)D,(42.30 ± 1.25)D vs.(43.21 ± 1.28)D,P < 0.05].After treatment,SE of control group significantly increased[(-4.65 ± 1.29)D vs.(-3.55 ± 1.27)D,P < 0.05],axis oculi significantly prolonged[(25.16 ± 0.55)mm vs.(24.30 ± 0.53)mm,P < 0.05].Research group had no serious corneal infection happened during the treatment.Conclusion Orthokeratology lens can effectively reduce the degree of myopia and slow down the axis oculi growth,and it is used convenient with high security.
