【摘要】：目的观察低中度近视患者行准分子激光原位角膜磨镶术(LASIK)后4~5年对比敏感度(CS)的变化。方法选择正视眼飞行员22例(44眼)、低中度近视飞行学员33例(64眼)、LASIK术后4~5年飞行学员15例(29眼)。应用CSV-1000 CS仪分别进行单眼明视、暗视、暗视+眩光3种环境下不同空间频率(3、6、12、18 cpd)CS的检测,分别对其进行单因素方差分析比较。结果低空间频率(3 cpd)在3种环境下3组人群CS值无统计学差异(P0.05);除6 cpd、18 cpd暗视+眩光下飞行员CS值优于LASIK术后和近视眼外,其他各种情况LASIK术后的CS值均与正视眼飞行员之间无统计学差异(P0.05),而飞行员CS值明显优于低中度近视学员,差异有统计学意义(P0.05)。结论低中度近视患者行LASIK术后远期CS值基本能够达到飞行员水平。
[Abstract]:Objective to observe the changes of contrast sensitivity (CS) in low and medium myopia patients after laser in situ keratomileusis (LASIKI) for 4 ~ 5 years. Methods A total of 22 pilots (44 eyes) with positive vision and 33 pilots with low and moderate myopia (33 / 64 eyes) were enrolled in this study. 15 flying cadets (29 eyes) from 4 to 5 years after LASIK underwent LASIK. CSV-1000 CS was used to detect monocular vision and dark vision glare in three environments. The spatial frequency was 61212 ~ (18 cpd)CS), and the variance analysis of single factor was carried out. Results there was no significant difference in CS value among the three groups under three conditions except for 6 cpdfg 18 cpd dark vision glare, the CS value of the pilots was better than that of LASIK and myopia, except for 6 cpdfg 18 cpd dark vision glare, there was no significant difference in CS value between the three groups. There was no significant difference in CS value between LASIK and positive vision pilots (P 0.05), but the CS value of pilots was significantly better than that of low moderate myopia students (P 0.05). Conclusion the long-term CS of low and moderate myopia patients after LASIK can reach the pilot level.
