【摘要】 目的 评价小光斑飞点扫描式准分子激光LASIK治疗高度近视的效果。方法 采用德国SCHWIND ESIRIS准分子激光机对364例（721眼）高度近视进行了LASIK治疗。切削模式采用单区或多区切削，切削总量为78～187μm。随访3～12个月，观察术后视力、屈光度和并发症等情况。结果 术后裸眼视力≥1.0者，术后1天、3个月时分别为72.0%（519/721）、81.7%（589/721）；术后屈光度在±1.00D以内者，术后1天、3个月时分别为：89.7%（647/721）、90.7%（654/721）。主要的并发症有：偏中心切削3眼(0.42%)、瓣位置偏离5眼(0.69%)、角膜上皮植入5眼(0.69%)、眩光15眼(2.08%)。结论 小光斑飞点扫描式准分子激光LASIK治疗高度近视的临床效果安全有效，但是需要切削较多的角膜组织。

【Abstract】 Objective To evaluate the clinical effect of high myopia treated with LASIK by a small optical zones flying-spot scanner machine.Methods 364 cases (721 eyes) of high myopia were treated with LASIK by the SCHWIND ESIRIS laser machine with small optical flying-spot scanner.The ablation zone was single-zone or multi-zone.The ablation depth was range of 78～187μm.All cases were followed up for 3～12 months.The changes of their visual acuities，subjective manifest refraction and complications were observed.Results Postoperatively，at one day and 3 month the visual acuities were 1.0 or better in 72.0%（519/721） and 81.7%（589/721）.The diopter within ±1.00 was 89.7%（647/721） and 90.7%（654/721）respectively.The complications include:decentral ablation 3 eyes (0.42%)，decentral flap 5 eyes (0.69%)，epithelial ingrowth 5 eyes(0.69%)，glare 15 eyes(2.08%).Conclusion The clinical effect of high myopia treated with LASIK by a small optical zones flying-spot scanner machine was safety and efficacy，although it needs more corneal tissues.
