目的探讨角膜塑形镜矫治青少年近视疗效.方法观察2010年5月至2011年6月配戴夜戴型角膜塑形镜且资料完整的患者45例,88只眼.其中男20例,女25例,年龄9～22岁,平均(14.21±1.19)岁.近视度数:球镜1.00～6.25 D,平均(3.34±1.55)D；柱镜0.25-1.00D,平均(0.57±1.32)D.采用夜间配镜8～10 h.戴镜后1周、1月、3月、6月随访,观察视力、角膜曲率、屈光度及眼轴长度变化.结果与戴镜前相比,戴镜1周后,角膜曲率明显变平,差异有统计学意义(P＜0.01).视力,戴镜前0.190±0.16,戴镜后1周及1、3、6月分别提高至0.75±0.27、0.95±0.11、0.96±0.13、0.95±0.13,戴镜前比较差异显著有统计学意义(P＜0.01),屈光度与戴镜前比亦下降,差异显著有统计学意义(P＜0.01).眼轴长度较戴镜前有所增长,但差异无统计学意义(P＞0.05).戴镜后少数患者有点状角膜上皮剥脱,结膜炎等,经治疗后均恢复.角膜塑性镜治疗近视达到矫治稳定状态后,停戴则裸眼视力回退明显.屈光度一般3个月恢复.结论角膜塑形镜矫治青少年近视疗效确切、安全、快速,可控制近视的发展.是一种可逆非根治性矫治近视的方法.

Objective To investigate the effect of orthokeratology in treatment of yang people with myopia.Methods Totally forty-five patients (88 eyes,20males and 25 females,aged from 9 to 22 years old) with-1.00 ～-6.25DS and astigmatism-0.25 ～-1.00DC received orthokeratology lens treatment in our hospital from August 2009 to July 2011 were observed.All patients were fitted with overnight orthokeratalogy for 8-10 hours at night.The visual acuity,corneal curvature,refraction and the axial length were measured at 1 week,1 month,3 months,6 months after wearing orthokeratalogy.Results Compared with the past,the corneal curvature became lower after 1 week's wearing and the difference was significant (P ＜0.01).Uncorrected visual acuity was 0.75±0.27,0.95±0.11,0.96±0.13,0.95±0.13 at 1 week,1 month,3 months,6 months after wearing orthokeratalogy,respectively.The refraction was 1.33±0.97(D),0.89±0.54(D),0.80±0.35(D),0.73±0.25(D),respectively.The difference was significant (P ＜0.01) compared with the past.The axial length increased (0.09±0.25)mm after wearing orthokeratalogy for 6 months but without a significant difference (P ＞0.05).Only a few patients had a mirror patch corneal epithelium desquamation,conjunctivitis,etc and all could be restored after therapy.Bared visual acuity went back obviously if stop wearing orthokeratology lens.Diopter would recover in 3 months.Conclusions Overnight orthokeratology is an effective and safe for the treatment of adolescent myopia.It is a reversible treatment of myopia.
