目的观察准分子激光原位角膜磨镶术(excimerlaserinsitukeratomileusis,LASIK)的术中术后并发症,探讨其发生的种类,原因,处理方法及预防措施。方法对523例(1011眼)LASIK术中术后并发症的发生、发展及影响进行了6个月的观察。结果LASIK术中并发症有角角膜血管翳出血,角膜瓣不规则游离,角膜瓣偏位,角膜瓣形成不全和角膜层间异物;术后出现多种并发症如切削区明显偏位,中心岛形成,瓣下中央区感染,不规则散光,角膜瓣皱褶,角膜瓣下上皮植入,屈光过矫,欠矫,屈光回退,眩光,激素性高眼压和干眼症。多数并发症经治疗和处理后,未对视功能产生明显影响。结论LASIK治疗近视安全、有效,但存在许多并发症,应引起重视。手术技巧的提高、手术设计的完善和手术设备的改进以及有效及时处理各种并发症是保证手术成功的关键。
Objective To observe the intraoperative and postoperative complications of excimer laser in situ keratomileusis (LASIK) and discuss the types, causes, treatments and preventive measures. Methods The incidence, development and impact of postoperative complications in 523 cases (1011 eyes) of LASIK were observed for 6 months. Results The complications of LASIK were keratoconjunctival hemorrhage, irregular corneal flap release, corneal flap deviation, corneal flap insufficiency and corneal intercostal foreign body. There were various complications such as significant deviation of the cutting area and central island Formation, sublatum central area infection, irregular astigmatism, corneal flap folds, corneal flap epithelialization, refractive correction, undercorrection, refractive regression, glare, elevated intraocular pressure and dry eye syndrome. The majority of complications after treatment and treatment did not significantly affect the visual function. Conclusions LASIK is safe and effective in the treatment of myopia, but there are many complications that deserve attention. Improve the surgical skills, surgical design and improvement of surgical equipment and effective treatment of various complications in a timely manner to ensure the success of surgery is the key.
