摘要
目的:观察高度近视患者在行准分子激光原位角膜磨镶术(LASIK)后不同时间泪膜及泪液分泌功能减弱的发生率。方法:对本院眼科行准分子激光治疗的82例(164眼)轻中度近视患者,54例(108眼)高度近视患者在行LASIK术后1周、1、3、6月作BUT及SchirmerⅠ泪液分泌检查。结果:高度近视患者在行LASIK术后6个月内泪膜稳定性下降的发生率及术后3个月内泪液分泌功能减弱的发生率均较轻中度近视患者显著增高(P<0.05),但两组的发生率均随时间的推移而减少。结论:高度近视患者在LASIK术后泪膜稳定性及泪液分泌功能降低持续时间较长,但最终可随着时间的推移而缓解。
Objective：To investigate the incidence of oligodacrya and tear film stability after LASIK for high myopic eyes at different time spots.Methods：164 eyes with low and moderate myopia and 108 eyes with high myopic after LASIK were randomly checked with Schirmer tear test,and studied for tear break-up time before and at 1 week,1 month,3 months,6 months after the operation.Results：The incidence of oligodacrya in high myopic eyes was obviously higher than that in low and medium myopic ones 6 months after the operation,and the incidence of decreased tear film stability in high myopic eyes was obvious higher than that in low and medium myopic ones 3 months after the operation.However,the incidences of these findings declined over time.Conclusion：The duration of the oligodacrya and decreased tear film stability after LASIK lasted longer with high myopic eyes,but the both improved over time.
