AIM: To evaluate flight attendants' ocular surface after different refractive corrections.

METHODS: Forty-two flight attendants(84 eyes)were enrolled in the study. Those flight attendants, who were followed up from September 2014 to September 2016, all followed the doctor's orders. According to different refractive corrections, those flight attendants were divided into 4 groups: corneal refractive surgery group, soft contact lens group, rigid gas permeable contact lens(RGP)group and control group without any refractive corrections. OSDI scores, tear meniscus heights, BUTs, fluorescein staining scores and Schirmer's tests were taken and analyzed.

RESULTS: Compared with the control group, OSDI scores were worse, tear meniscus heights(TMH)were reduced, BUTs were shortened, fluorescein staining(FS)scores were worse, Schirmer's Tests(SⅠt)were shorter in soft contact lens group and corneal refractive surgery group(P<0.05). However, the above parameters did not change significantly in RGP group(P>0.05). There was no significant difference in lid margin abnormalities among the four groups(F=3.82, P=0.45).

CONCLUSION: RGP can improve flight attendants' ocular surface micro-environment.
