目的:探讨近视患者配戴角膜塑形镜( orthokeratology, Ortho-K镜)前后视觉质量的变化情况。<br> 方法:选取江苏省溧阳市中医院眼科验配角膜塑形镜55例110眼青少年近视患者,在戴镜前、戴镜后7d,1、3、6mo五个时间点利用 OQASTMⅡ视觉质量分析系统和Topolyzer角膜地形图进行检测,分别获得各参数:眼散射指数( optical scattering index,OSI)、MTF 截止频率( MTF cut off )、斯特列尔比( Strehl ratio )、OQAS 值( OV100%、OV20%、OV9%)、高度不对称性指数( index of highest asymmetry, IHA )、高度离心指数( index of highest decentration,IHD)和不规则指数( aberration coefficient, ABR)。<br> 结果:角膜塑形镜戴镜前裸眼视力为0.21±0.13,戴镜后7d,1、3、6mo分别为0.48±0.15、0.72±0.14、0.93±0.13、1.02±0.13,差异有统计学意义(P<0.05)。 OSI配戴前与配戴后1、3、6 mo比较具有统计学差异( P<0.05)。 MTF cut off配戴前与配戴后1、3、6mo比较具有统计学差异( P<0.05)。 Strehl ratio配戴前与配戴后1、3、6mo比较具有统计学差异( P<0.05)。 OV9%配戴前与配戴后1、3、6 mo比较具有统计学差异(P<0.05)。 IHA配戴前与配戴后1、3、6mo分别为4.13±3.59、19.11±15.38、17.78±17.12、34.18±23.34,与配戴前相比差异均有统计学意义( P<0.05)。 IHD配戴前与配戴后7d,1、3、6mo分别为0、0.02±0.01、0.02±0.02、0.03±0.02、0.03±0.01,与配戴前相比差异均有统计学意义(P<0.05)。 ABR配戴前与配戴后7d,6mo分别为0.29±0.51、1.23±0.71、2.10±0.59,与配戴前相比差异均有统计学意义(P<0.05)。<br> 结论:夜戴型角膜塑形镜可引起视觉质量的下降,但下降程度轻微。角膜塑形镜治疗青少年初发性近视效果确切,角膜塑形镜能快速、有效地提高裸眼视力,在控制青少年近视发展方面是值得肯定的。

?AIM:To explore the changes of visual quality in myopic eyes undergoing overnight orthokeratology. <br> ?METHODS:Fifty-five myopia adolescents ( 110 eyes ) were recruited .Optical scattering index ( OSI ) , MTF cut off, Strehl ratio, OQAS value ( OV100%、OV20%、OV9%) , index of highest asymmetry ( IHA ) , index of highest decentration ( IHD ) , aberration coefficient ( ABR ) were performed before and 1wk, 1, 3 and 6mo after wearing orthokeratology with OQASTMⅡand corneal topography.?RESULTS:The uncorrected visual acuity ( UCVA) before wearing orthokeratology lens was 0.21±0.13,but at 1wk,1, 3 and 6mo after wearing were 0.48 ±0.15,0.72 ±0.14,0.93 ± 0.13 and 1.02±0.13,respectively,and there were statistical differences before and after wearing ( P<0.05 ) .On OSI after wearing at 1,3 and 6mo compared with that before wearing, there were significant differences ( P<0.05 ) .On MTF cut off after wearing at 1,3 and 6mo compared with that before wearing, there were significant differences( P<0.05 ).On Strehl ratio after wearing at 1, 3 and 6 mo compared with that before wearing, there were significant differences(P<0.05).On OV9% after wearing at 1,3,6 mo compared with that before wearing, there were significant differences(P<0.05).IHA were 4.13 ±3.59, 19.11 ±15.38, 17.78±17.12, 34.18±23.34 before and 1, 3 and 6 mo after wearing. Compared with that before wearing, IHA significantly increased (P<0.05).IHD were 0, 0.02±0.01, 0.02±0.02, 0.03±0.02, 0.03±0.01 before and 1wk,1, 3 and 6mo after wearing.Compared with that before wearing, IHD were significantly increased (P<0.05).ABR were 0.29± 0.51, 1.23±0.71, 2.10±0.59 before and 1wk and 6mo after wearing.Compared with that before wearing, ABR were significantly decreased (P<0.05). <br> ? CONCLUSION: Orthokeratology deteriorates vision quality.But the loss is acceptable.Orthokeratology can improve UCVA quickly and effectively. It is worth of affirmation on control of myopia.
