方法：将80例160眼南航空中乘务员分为两组：对照组配戴现成博士伦软性角膜接触镜(曲率为8.4)40例80眼； 试验组配戴定制角膜曲率博士伦软性角膜接触镜40例80眼。测量试验前后泪膜破裂时间(BUT)、泪液分泌试验(SⅠt)和荧光素染色(FL)作为干眼症评估指标并对结果进行统计分析。

结果：BUT、SⅠt平均值缩短量试验组均比对照组较少，有显著统计学意义(P<0.01)。FL阳性增加数试验组比对照组较少，有统计学意义(P<0.05)。

结论：配戴定制曲率软性角膜接触镜较固定曲率现成品更有效预防空中乘务员干眼发生。

METHODS: Eighty cases(160 eyes)of flight attendants from China Southern were divided into two groups: control group 40 cases(80 eyes)wearing ready-made Bausch soft corneal contact lens(curvature 8.4); the experiment group 40 cases(80 eyes), wearing Bausch soft corneal contact lens with customized curvature. Tear break-up time(BUT), Schirmer Ⅰ test(SⅠt)and fluorescein(FL)staining were as dry eye evaluation index. The results was statistically analyzed.

RESULTS: BUT, SⅠt average shortening value of the experimental group were less than that of the control group, there was statistical significance(P<0.01). FL staining positive increase, the number of experimental group was fewer than that of control group, with statistical significance(P<0.05).

CONCLUSION: Wearing customized curvature soft corneal contact lens can prevent the flight dry eye more effectively than fixed curvature product.
