目的:探讨准分子激光原位角膜磨镶技术(laser in situker-atomileusis,LASIK)治疗高度近视的疗效。方法:应用日本Nidek EC5000Ⅱ准分子激光仪,采用多步分区切削法治疗高度近视。按屈光度分为两组,I组:-6.00～-9.00D,128眼;II组:-9.00～-...目的:探讨准分子激光原位角膜磨镶技术(laser in situker-atomileusis,LASIK)治疗高度近视的疗效。方法:应用日本Nidek EC5000Ⅱ准分子激光仪,采用多步分区切削法治疗高度近视。按屈光度分为两组,I组:-6.00～-9.00D,128眼;II组:-9.00～-14.00D,147眼。术后随访1a,并对结果进行分析。结果:两组患者术后1a裸眼视力≥0.6者占89.6%,≥1.0者占55.6%(其中I组≥0.6者占95.1%,Ⅱ组≥0.6者占88.9%)。术后最佳矫正视力大于术前者占38.1%,小于术前者占6.0%,94.0%术后最佳矫正视力不变或上升。术后1a实际矫正度在预测矫正度±1.00D内者占81.3%,±2.00D内者占90.2%。激素性高眼压占0.04%。结论:准分子激光原位角膜磨镶技术多步分区切削法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。展开更多

Methods According to the preoperative diopters of the myopia, patients, undergoing LASIK, were divided into three groups, group Ⅰ: 140 eyes ( -1. 25D ~ -6. 00 D) , group Ⅱ : 205 eyes ( -6. 25D ~ -10. 00D) , group Ⅲ: 226 eyes ( -10.25D- -15.00D). The patients were followed up at least I year. Results By groups, the percentage of the uncorrected visual acuity equal or more than 1. 0 were 94. 29% , 80. 30% , 42. 04% respectively. The residual refractive error within 0. 5D were 99. 29% , 85. 71% , 59. 70%. The spherical equivalent was stable 3 months after LASIK. The complications were few. Conclusion LASIK is a safe, effective and good predictable method for the treatment of myopia. It is one of the best choices to treat myopia below -10. 00D.展开更多
