  风沙迷眼主要是指角膜和结膜异物,其自觉眼内有异物感,有怕光流泪、磨痛等症状,如风沙迷眼后迅速眨眼,异物可被推向上睑沟或穹窿处隐藏起来,或被泪水给冲至睑结膜囊内而使症状消失;如症状一直存在可用手将眼皮翻转看见小异物后用湿棉签拭去;如较深居的异物,可先点0.5%地卡因作表面麻醉后,翻转眼睑用生理盐水冲洗出或用棉签拭去异物。

  角膜异物不及时取出可继发角膜感染而影响视力,取角膜异物要在良好的照明条件下进行严格的无菌操作,先点地卡因表面麻醉,用湿棉签拭去角膜异物,涂消炎油膏单眼遮盖,次日复诊检查;若异物在前弹力层或浅层基质内,可令患者眼球不动,用异物针或注射针头将异物剔去;若异物深至角膜层间,可做角膜板层切开剔除异物。
