1、智慧型光斑LASIK治疗近视临床分析作者：冯华章，张建华，郑磊，樊琪，王红英【摘要】目的：探讨智慧型光斑LASTK治疗近视或近视散光可预测性、稳定性、有效性及术后残留屈光度危险因素分析。方法：回顾性分析200810/200910在我中心行LASIK病例,术前最佳矫正视力(BCVA)N0.8,随访时间球镜<10.00D纳入统计分析病例,共768例。按激光切削模式及屈光度分组，对术后裸眼视力，术后1,3,6mo；la残留等效球镜，屈光回退患者术前术后数据行统计学分析。结果：10例BCVA术后未达术前；预测性：术后常规组98.0%SE<0.50D,99.2%SE<1
2、.00D；波前组97.4%SE<0.50D,99.3%SE<1.00D；术后残留屈光度，常规组:lino：0.01±0.10D；3mo：0.02±0.20D；6mo：0.07±0.31D；la：0.15±0.38DO波前组：Imo：0.01±0.08D；3mo：0.01±0.09D；6mo：0.03±0.150；la：0.08土0.19D；视力改变，常规组：0±0.05,波前组：0.01±0.04o23例术后残留屈光度危险因索分析，术后残留球镜与年龄，术前球镜有关，术后球镜=1.3550.034年龄+0.142术前球镜；术后残留柱镜与术前柱镜，术前中央角膜厚度有关，
3、术后柱镜二3.489+0.238术前柱镜0.007术前中央角膜厚度。结论：智慧型光斑LASTK预测性，稳定性，有效性均较好,波前像差引导LASTK在预测性及有效性方血更优，两种术式均有较好的稳定性；术后残留球镜危险因索：年龄、术前球镜，术后残留柱镜危险因素：术前柱镜、术前中央角膜厚度。【关键词】近视；LASIK；屈光度AbstractAIM:Toevaluatethepredictability,stability,efficacyoflaserinsitukeratomi1eusis(LASTK)usingvariedsizespotlaserforthetreatmento
