目的观察准分子激光上皮瓣下角膜磨镶术(LASEK)后丝状角膜病变的发病情况,探讨其发病相关因素及防治方法。方法将接受LASEK的263例(526眼)近视按术前有无角膜接触镜配戴史分为两组,观察术后丝状角膜病变的发生及治疗情况。结果术后发生丝状角膜病变共15例(27眼),发病率为5.13%,有角膜接触镜配戴史组及无角膜接触镜配戴史组术后丝状角膜病变的发病率分别为7.59%、3.31%,两者有显著差异(P<0.05)。丝状角膜病变的治疗可采取将丝状物剔除及使用人工泪液。结论LASEK术后丝状角膜病变发生的相关因素包括:术前角膜接触镜的配戴、术中角膜上皮层及前弹力层的损伤、术后用药等。对于术后丝状角膜病变,应采取积极的预防及处理。
Objective To observe the incidence of filamentous keratopathy after excimer laser epithelial keratomileusis (LASEK) and to explore the related factors and prevention and treatment methods. Methods Totally 263 cases (526 eyes) of myopia undergoing LASEK were divided into two groups according to the history of contact lens wear before surgery. The occurrence and treatment of fibroids after operation were observed. Results The incidence of postoperative filamentous keratopathy in 15 cases (27 eyes), the incidence rate was 5.13%, with contact lens wear history group and non-contact lens wear history group the incidence of fibroaltic lesions were 7.59% and 3.31%, respectively (P <0.05). Treatment of filamentous keratopathy can take the filament removed and the use of artificial tears. Conclusion The related factors of fibrogenesis after LASEK include: preoperative contact lens wear, intraoperative corneal epithelial and anterior elastic layer of injury, postoperative medication. For postoperative filamentous keratopathy, should take active prevention and treatment.
