目的:比较分析虹膜定位引导的前弹力层下准分子激光角膜磨镶术( SBK)和虹膜定位引导的超薄瓣准分子激光原位角膜磨镶术( LASIK)治疗超高度近视的疗效。<br> 方法:超高度近视患者行虹膜定位引导的SBK治疗的患者32例64眼,行虹膜定位引导的超薄瓣LASIK治疗的患者42例84眼,年龄22~35岁,术前等效球镜屈光度-9.00~-11.00D,随访6mo观察两术式的治疗效果。观察指标包括裸眼视力( UCVA)、屈光状态、裂隙灯检查、残余角膜基质床厚度、角膜地形图、角膜厚度、角膜瓣厚度并发症。<br> 结果:术后随访6mo,UCVA≥1.0者SBK组为93.8%,超薄瓣LASIK组为92.9%,两术式相比较差异无统计学意义;残余屈光度在±0.50 D以内者SBK组为89.1%,超薄瓣LASIK组为84.5%,两术式相比较差异无统计学意义;SBK组角膜后表面 Diff 值为0.046±0.012μm,超薄瓣LASIK组为0.056±0.015μm,两术式相比较差异无统计学意义;术后 SBK 组角膜中央残余基质厚度为328.6±14.7μm,超薄瓣LASIK组为301.2±21.6μm,两组相比较差异有显著性( t=3.127, P=0.001);SBK 组、超薄瓣LASIK组患者泪膜破裂时间( BUT )分别为11.38±4.02 s和17.81±4.89s,两组相比较差异无统计学意义。术后两组患者均无严重并发症。<br> 结论:虹膜定位引导的SBK和超薄瓣LASIK治疗超高度近视具有良好的效果,与LASIK相比SBK制作角膜瓣的预测性更好,可以降低医源性圆锥角膜发生的概率;术后干眼症状轻、恢复更快,对于超高度近视患者来说是一种经济有效的手术治疗方式。

?AlM:To compare the effect of iris location guided sub-bowman keratomileusis ( SBK ) and iris location guided thin - flap laser in situ keratomileusis ( LASlK ) for extremely high myopia treatment. <br> ?METHODS:lris location guided SBK was performed in 64 eyes of 32 patients with extremely high myopia and 42 eyes of 84 patients were received iris location guided thin-flap LASlK. All the patients’ spherical refraction was-9. 00D ~ - 11. 00D and the age was 22 ~ 35 years. Uncorrected visual acuity ( UCVA) , refraction, split-lamp examination, topography examination, central corneal stroma thickness, thickness of central corneal flap, thickness of peripheral corneal flap and complication was examined in these patients and follow-up was 6mo. <br> ?RESULTS:At 6mo after surgery, 93. 8% of the patients received iris location guided SBK and 92. 9% received iris location guided thin-flap LASlK achieved a UCVA better than 20/20. There was no significant difference between two groups. Refraction between ±0. 5D was 89. 1% of SBK group and 84. 5% of LASlK group. There was no significant difference. Corneal rear surface height of SBK was 0. 046±0. 012μm and LASlK was 0. 056±0. 015μm. Thickness of corneal stroma after surgery was 328. 6±14. 7μm in SBK group, while it was 301. 2±21. 6μm in LASlK group and there was significant difference ( t =3. 127, P=0. 001). BUT was 11. 38±4. 02s and 17. 81±4. 89s in SBK and LASlK group respectively, with no statistical difference. There was no serious complication in two groups.?CONCLUTlON:Both iris location guided SBK and thin-flap LASlK are effective for extremely high myopia, but SBK is safer and more predictive than thin-flap LASlK.
