目的：通过将行准分子激光原位角膜磨镶术( LASIK)后的飞行员与正视眼和戴镜飞行员的对比敏感度( CS)进行比较,为手术后的体检鉴定标准提供依据。 　　方法：选择正视眼飞行员13例26眼、中低度近视飞行员12例24眼、LASIK术后6 mo以上飞行员10例20眼,分别进行明视、暗视、暗视+眩光3种环境下4种空间频率(3,6,12,18 cpd )的对比敏感度检测,并对结果进行统计学分析。 　　结果：明视下除在低频(3 cpd )下,三组CS无统计学差异(P>0.05),其他中高频下对照组均高于戴镜组和手术组(P<0.05),戴镜组与手术组间比较差异无统计学意义(P>0.05)；暗视低频(3cpd)下,三组 CS 无统计学差异( P>0.05),中高频率下对照组和手术组CS值高于戴镜组,差异有统计学意义(P<0.05),对照组CS值高于手术组,差异无统计学意义(P>0.05)；暗视+眩光环境下各个空间频率时对照组明显高于戴镜组和手术组,差异有统计学意义(P<0.05),戴镜组高于手术组,但两者间差异无统计学意义(P>0.05)。 　　结论：准分子原位角膜磨镶术后飞行员的对比敏感度较正视眼有所降低,在暗视+眩光环境下更为明显,需建立更为完善的术后鉴定和放飞标准。

AIM: To observe the changes in contrast sensitivity (CS) between emmetropic pilots, glasses wearing, and after laser in situ keratomileuses ( LASIK) surgery pilots, provide the basis for the physical examination standard after operation. METHODS:The CS of 13 emmetropic pilots (26 eyes), 12 glasses wearing pilots (24 eyes) and 10 with LASIK (20 eyes) , under photopic, scotopic and scotopic with glare environments at four different spatial frequencies ( 3, 6, 12 and 18cpd ) were measured and the resluts were analyzed by statistics. RESULTS:Under photopic environments, there was no significant difference in the low spatial frequency (3cpd) among the three groups (P>0. 05). The CS of emmetropic pilots was better than that of the myopic and with LASIK, and there was significant difference (P<0. 05). There was no significant difference in CS between myopic and with LASIK (P>0. 05). Under scotopic environments, there was no significant difference in the low spatial frequency (3cpd)among the three groups (P>0. 05). The CS of emmetropic and with LASIK pilots were better than that of the myopic, and there was significant difference ( P<0.05). There was no significant difference in CS between emmetropic and with LASIK (P>0. 05). Under scotopic with glare environments, the CS of emmetropic and myopic pilots were better than that of the with LASIK, and there was significant difference (P<0. 05). There was no significant difference in CS between myopic and with LASIK (P>0. 05). CONCLUSION: The CS after LASIK is decreased compare with emmetropic pilot, specially under scotopic with glare environments. A perfect identification standard should be set up.
