摘　　要：目的 :探讨准分子激光原位角膜磨镶术 (laserinsitukeratomileusis,LASIK)中角膜血管翳的出血位置 ,以避免和减少术中出血。方法 :对 48例 84眼LASIK中角膜血管翳出血的位置进行分析。全部瓣采用MoriaCB旋转式角膜板层刀进行角膜瓣制作 ,角膜瓣直径为 9.5mm ,角膜瓣蒂位置右眼留在上方 ,左眼留在内侧 ,蒂宽为 4～ 5mm。结果 :5 2 8例中有 48例发生了角膜血管翳出血 ,发生率为 9.1%。角膜缘上方、下方、上下方、鼻侧、颞侧出血的眼数分别为 31眼(占 36 .9% ) ,2 3眼 (占 2 7.4% ) ,14眼 (占 16 .7% ) ,9眼 (10 .7% ) ,7眼 (占 8.3% ) ;上方蒂和鼻侧蒂角膜瓣发生出血的眼数分别为 35眼和 49眼。结论 :LASIK中角膜血管翳出血的部位以角膜上下方为多见 。Objective:To investigate the location of intraoperative corneal pannus hemorrhage during laser in situ keratomileusis(LASIK).Methods:The location of intraoperative corneal pannus hemorrhage during LASIK was analyzed in 48 cases(84 eyes). A 9.5 mm diameter superior hinge in the right eye or nasal hinge in the left eye allowing a corneal flap with a 4～5 mm wide pedicle was created using a moria CB microkeratome.Results:Of the 528 cases that underwent LASIK,there were 48 intraoperative corneal pannus hemorrhage cases(84 eyes),an incidence rate of 9.1%. The corneal pannus hemorrhage was located on the superior,inferior,superior and inferior,nasal and temporal corneal limbus,with an incidence of 31(36.9%),23(27.4%),14(16.7%),9(10.7%) and 7(8.3%),respectively. There were 35 eyes with an upper pedicle and 49 eyes with a nasal pedicle in which corneal pannus hemorrhage occurred.Conclusion: Intraoperative corneal pannus hemorrhage during LASIK is more common on the superior and inferior corneal limbus.
