准分子激光原位角膜磨镶术治疗高度近视的并发症

Complications of excimer laser in situ keratomileusis for high myopia

目的 :分析准分子激光原位角膜磨镶术 ( L ASIK)治疗近视的并发症 ,探讨其发生原因及预防和处理措施。方法 :182例 ( 3 60眼 )近视患者 ( 6.0 0～ - 10 .0 0 D)行 L ASIK,术后随访 12月 ,观察并分析其并发症。结果 :术中负压吸引失败 4眼 ( 1.1% ) ,角膜瓣形成不全 1眼 ( 0 .2 8% ) ,游离瓣 2眼 ( 0 .5 6% ) ,角膜血管翳出血 8眼 ( 2 .2 % ) ,角膜瓣层间异物残留 7眼 ( 1.9% ) ,结膜下出血 60眼 ( 16.7% ) ;术后眩光及夜驶困难 9眼 ( 2 .5 % ) ,偏中心切削 >0 .5 mm15眼( 4 .2 % ) ,中央岛形成 2眼 ( 0 .5 6% ) ,术后 12月屈光回退 >1.0 0 D者 9眼 ( 2 .5 % )。结论 :L ASIK治疗高度近视安全有效 ,但仍存在并发症。提高手术技巧和完善手术设计 ,有助于进一步减少并发症和提高手术的安全性和准确性。

Objective: To analyze the complications of excimer laser in situ keratomileusis (LASIK) for high myopia. Methods: LASIK was run on 360 eyes in 182 patients with high myopia. All of them were followed up for a period of 12 months. Results: In 360 eyes, there were intraoperative inadequate suction 4 eyes (1.1%), incomplete cap 1 eye (0.28 %), free cap 2 eyes (0.56 %), corneal pannus hemorrhage 8 eyes (2.2%), interface debris 7 eyes (1.9%), subconjunctival hemorrhage 60 eyes (16.7%), postoperative night glare: 9 eyes (2.5%), eccentric ablation (> 0.5mm) 1 5 eyes (4.2 %), central inlands 2 eyes (0.56 %), and refraction regression (>1.00D) at postoperative 12 months 9 eyes (2.5%). Conclusions: LASIK was a safe effective method for correcting high myopia, although there were complications
