SBK技术多光区切削治疗高度近视

Multi-step SBK Technologies District Cutting Rule Efficacy of Treatment of High Myopia

目的探讨准分子激光前弹力层下角膜磨镶技术(SBK)治疗高度近视的疗效。方法应用德国SCHWIND公司生产的AMARIS 500Hz准分子激光仪,采用多光区切削治疗>6.00D高度近视患者156例(310眼)。术后随访1年。结果术后1年,裸眼视力≥0.6者129例(82.69%),≥1.0 71例(45.51%)。术后最佳矫正视力大于术前54例(34.62%),术后1年实际矫正度在预测矫正度±1.00D内130例(83.33%),±2.00D内146例(93.59%)。激素性高眼压2例(1.28%)。结论 SBK技术多光区切削治疗高度近视伴薄角膜及超高度近视是一种安全、有效,且稳定性较好的方法,能有效预防屈光回退的发生,同时可以减少术后眩光和暗视力下降等现象。

Objective To study the effect of laser sub-bowman keratomileusis Technology（ SBK） effect in the treatment of high myopia. Methods AMARIS 500Hz excimer laser instrument produced by Germany SCHWIND company was used, the cut-ting treatment of high Results One year postoperative uncorrected visual acuity≥0. 6 1a accounted for 82. 6%,≥1. 0 accoun-ted for 45. 6%. Best corrected visual acuity after surgery than the total of 34. 1%, 5. 4% less than the total of surgery, postopera-tive best corrected visual acuity accounted for 92. 6% of the same or increased. 1 year after correction of the actual degree of cor-rection in the forecast within ± 1. 00D accounted for 82. 9%,± 2. 00D accounted for 93. 2% within. Hormone ocular hyperten-sion accounted for 1. 28%. Conclusion SBK technology multi-zone step cutting method for high myopia with thin corneas and high myopia is a safe, effective, and good stability of the method can effectively prevent the occurrence of refractive regression, while reducing glare and after Dark vision loss and so on. Conclusion SBK technology multi-zone step cutting method for high myopia with thin corneas and high myopia is a safe, effective, and good stability of the method can effectively prevent the occurrence of re-fractive regression, while reducing glare and after Dark vision loss and so on.
