Abstract:
AIM: To discuss the effect of wearing customized curvature soft corneal contact lens to dry eye degree of flight attendants.
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.
