【摘要】 目的:分析准分子激光原位角膜磨镶术(laserinsitu keratomileusis,LASIK)治疗近视的并发症,探讨其发生的机制及预防措施。方法:2648例(5060眼)近视患者(-1.00～-21.00D),行LASIK后随访12mo,观察其并发症的发生,并分析其原因。结果:术中角膜血管翳出血416眼(8.22%),角膜瓣游离6眼(0.12%),不完全角膜瓣13眼(0.26%),角膜瓣偏位62眼(1.22%),角膜瓣层间异物106眼(2.09%),结膜下出血1274眼(25.18%),下睑皮肤划伤52眼(1.03%)。术后并发症:偏中心切削102眼(2.02%),角膜瓣皱褶和移位9眼(0.18%),弥漫性板层角膜炎43眼(0.85%),中央岛形成11眼(0.22%),屈光回退275眼(5.10%),眩光76眼(1.5%),激素性高眼压23眼(0.45%),最佳矫正视力下降6眼(0.12%),过矫63眼(1.24%),干眼症41眼(0.81%)。结论:LASIK治疗近视安全、有效,但仍存在并发症,手术设计的完善和手术技巧的提高可减少并发症的发生。更多还原

【Abstract】 AIM: To analyze the complications of laser in situ keratomileusis for myopia, and to discuss the causes and prevention of these complications.· METHODS: LASIK was run on 5 060 eyes in 2 648 patients with myopia. All of them were followed up for 12mo.· RESULTS: Among the 5 060 eyes, there were intraoperative corneal pannus hemorrhage in 416 eyes (8.22%), free cap in 6 eyes (0.12%), incomplete cap in 13 eyes (0.26%), decentered cap in 62 eyes (1.22%), interface debris in 106 eyes (2.09%), subconjunctival hemorrhage in 1 274 eyes (25.8%), sick of eyelid skin in 52 eyes (1.03%), postoperative eccentric ablation in 102 eyes (2.02%), ruffly cap in 9 eyes (0.18%), interface stromal infiltration in 43 eyes (0.85%), central inlands in 11 eyes (0.22%), refraction regression in 275 eyes (5.08%), night glare in 76 eyes (1.50%), intraocular hypertension in 23 eyes (0.45%), best corrected visual acuity decrease in 6 eyes (0.12%), overcorrection in 63 eyes (1.24%) and dry eyes in 41 eyes (0.81%).· CONCLUSION: LASIK was a safe and effective method for correcting myopia. Its complications can decrease with the improvement of operative technique and better designed procedure.更多还原
