超高度近视行准分子激光上皮下角膜磨镶术治疗远期疗效观察

目的探讨准分子激光上皮下角膜磨镶术（LASEK）治疗超高度近视（≥-10.00D）的远期效果。方法收集2003年12月～2006年1月在我院行LASEK的超高度近视患者83例151只眼，观察25～49个月，平均（35.34±6.45）月；术前裸眼视力0.01～0.1，平均0.053±0.025，最佳矫正视力0.5～1.2；平均0.998±0.145，术前屈光度－10.00～－14.50D，平均（－11.01±1.19）D。 结果术后25～49个月回访，裸眼视力0.2～1.5，平均1.01±0.26，≥1.0者120眼占79.47%，≥0.6者142眼占94.04%，haze 6眼，0.5级5眼，1级1眼。结论LASEK治疗超高度近视的远期疗效安全可靠，疗效稳定，并发症少，是治疗超高度近视较好的术式之一。

Long-term effect of laser subepithelial keratomileusis in the treatment of super-high myopia

To evaluate the long term effect of laser subepithelial keratomileusis(LASEK) for super high myopia(≥-10.00?D). MethodsEighty three cases (151 eyes)of super high myopia who had been treated with LASEK in our hospital from December 2003 to January 2006 were followed up from 25 to 49 months (mean 35.34±6.45 months). Before the operations, visual acuity, the best corrected visual acuity, and diopter was 0.01 0.1(mean 0.053±0.025), 0.5 1.2(mean 0.098±0.145), and -10.00～-14.50D(mean -11.01±1.19D), respectively. ResultsAfter the operations, visual acuity was 0.2 1.5 (mean 1.01±0.26), and was 1.0 or better in 120 eyes (79.47%), and 0.6 or better in 142 eyes (94.04%). In addition, 5 eyes had a 0.5 level Haze and 1 eye had a 1 level Haze. ConclusionLASEK is an effective and good method to correct super high myopia and is stable and safe with satisfactory visual acuity and less complication.
