准分子激光原位角膜磨镶术治疗近视眼391例疗效分析

Clinical observation of laser in situ keratomileusis in treatment of 391 patients with myopia

目的评价准分子激光原位角膜磨镶术(LASIK)治疗不同程度近视眼的疗效。方法对接受LASIK治疗391例772眼近视眼患者按屈光度不同分为低度(<-3.00D)、中度(-3.00D^-6.00D)、高度(-6.00D^-9.00D)、超高度(>-9.25D)近视4组。术后1年观察其视力、屈光度的变化。结果低度近视组100%、中度近视组98.6%、高度近视组95.7%患者术后1年的裸眼视力≥1.0,超高度近视组90.2%患者裸眼视力在1.0~0.8,与术前视力相比较有极显著差异(P<0.01);近视度数在±1.00D内,散光度数在±1.00D内,术后视力96.1%无下降,术后有6.3%的患者视力有回退,均为中度以上近视眼,经检验无显著差异(P>0.05)。术中无并发症出现。结论准分子激光原位角膜磨镶术治疗不同程度近视眼均有良好效果,是一种有效的、可预测的、安全的屈光手术。

Objective To investigate the clinical effect of laser in situ keratomileusis（LASIK） for treatment of different degree srnyopia. Methods According to the diopters（D） of myopia, 391 patients were divided into 4 groups： low myopia（ 〈 - 3.00D） ,moderate myopia（ - 3.00D-- - 6.00D）, high myopia （ - 6.00D-- - 9.00D）and extremely high myopia（ 〉 - 9. 25D）, follow - up was 1 year postperatively. Results The naked vision ≥1.0 on 1 year after operation in low myopia, moderate myopia and high myopia were 100 %, 98.6 % and 95.7 %, respectively, but was 1.0 - 0.8 in extremely high myopia（90. 2% ）. The vision regression was observed in 6.3% patients with preoperative higher astigmia（ 〈± 1.00D） and myopia（ 〈 ±1.00D）. Conclusion Using LASIK to treat different myopia is an effective,divinable and safe operation.
