目的评价小光斑飞点扫描准分子激光原位角膜磨镶术治疗LASIK术后残余近视的疗效及安全性.方法对75例93只眼LASIK术后残余近视的患者行二次LASIK手术,全部采用掀瓣的手术方式,两次手术间隔(7.18±3.56)个月.术后平均随访超过6个月.结果二次LASIK术后平均裸眼视力较术前显著提高(P＜0.01),术后裸眼视力与术前最佳矫正视力比较,差异无显著意义(P＞0.05);术后6个月时屈光度在±0.5 D以内者为90只眼(96.8%),20只眼(21.5%)术后裸眼视力大于术前最佳矫正视力.无危及视力的并发症出现.结论小光斑飞点扫描准分子激光原位角膜磨镶术治疗LASIK术后残余近视安全、效果好.

Objective To evaluate the effectiveness and safety of laser in situ keratomileusis (LASIK) for residual myopia and astigmatism using ascanning-spot laser.Methods Ninety-three myopia eyes (from 75 patients) underwent secondary LASIK at (7. 18 ?3. 56) months after primary LASIK procedure. Following up was 6 months. The statistical analysis of the data was made by the paired sampleit test.Results After retreatment, the uncorrected visual acuity (UCVA) improved significantly (P < 0. 01 ) , the UCVA after secondaryLASIK and the best corrected visual acuity (BCVA) after primary LASIK were with no significant difference(P>0. 05). At 6 months,the residual refractive error within ?. 5 D was 96. 8% (90 eyes). The rate of postoperative UCVA was 21. 5% (20eyes) , better than the preoperative BCVA . Severe complications were not observed.Conclusions The secondary LASIK is an effective and safe method to treat regression after primary LASIK using a flying spot scanningexcimer laser system.
