准分子激光原位角膜磨镶术治疗近视临床分析

目的 分析近视眼准分子激光原位角膜磨镶术(LASIK)治疗近视眼的效果.方法 对101例(197眼)近视眼行LASIK手术,按屈光度分为三组,Ⅰ组:<-6.00 D(57眼);Ⅱ组:-6.25～-10.00 D(109眼);Ⅲ组:>-10.25～-15.00 D(31眼).检查术前和术后1年的视力(裸眼视力和矫正视力)、屈光度、眼压、角膜厚度和角膜地形图.结果 术后裸眼视力≥1.0者在各组分布的比率分别是94.3%、80.3%、42.0%;残余屈光度≤±0.50 D分别是99.3%、85.7%、59.7%.屈光度在术后3个月稳定,术后并发症少.结论 LASIK是治疗近视艰较理想的手术方法之一.

Clinical analysis of the patients with myopia after LASIK

Objective To analyze the clinical effects aftet one year of LASIK for myopia. Methods According to the preoperative diopters of the myopia, the patients were divided into three groups, group Ⅰ: 57 eyes( < - 6.00D), group Ⅱ: 109 eyes( - 6.25～ - 10.00D) ,group Ⅲ :31 eyes( > - 10.25D～ - 15.00D). The patients were followed up 1 year. Re- sults In groups,the percentage of the uncorrected visual acuity equal or more than 1.0 was 94.3%,80.3%,42.0% re- spectivdy. The percentage of there sidual refractive error within ±0.50D was 99.3% ,85.7% ,59.7%. The spherical e- quivalent was stable in 3 months after LASIK. The complications are few. Conclusion LASIK is a safe,effective and good predictable method for treatment of myopia.
