摘要
目的探讨准分子激光原位角膜磨镶术（laser in situ keratomileusis ，LASIK）术后发生丝状角膜病变的病因。方法对439例869眼的近视患者行LASIK手术，术前根据泪膜破裂时间（the tearfilm break-up time ,BUT）分为两组，A组BUT为5—10s共187例370眼，B组BUT≥10s共252例499眼。结果术后两组均有丝状角膜病变的发生，A组中有10例14眼，双眼发病4例，占3．7％。BUT≥10s组中有2例，无双眼发病者，占0．4％。结论A组发病率明显高于B组，说明泪膜和丝状角膜病变的发生有密切联系。
Objective To analyze the. cause of filamentary keratopatlry after Iaser in situ keratomileusis （LASIK） for myopia. Methods 869 eyes of 439 patients were treated with LASIK who were divided into two groups according to the. tear film break-up time （BUT）. There were 370 eyes of 187 patients in group A （BUT 5＂- 10＂） and 499 eyes of 252 patients in group B （BUT≥ 10＂）. The morbidity of filamentary kerntopathy in two groups was compared. Results We find the. occurence of filamentary keratopathy in each group. The morbidity in group A is 2.7% and the morbidity in group B is 0.4%. Conclusion Obviously the morbidity of filamentary keratopathy in group A is higher than that in group B. There is a close relationship between the BUT and the happening of filamenttary deratopathy . So effective treatment of dry eye before and after LASIK can reduce the. rate of the. occurence of the. filamentary keratopathy
