摘　　要：目的 :评价使用飞点扫描技术的准分子激光原位角膜磨镶术 (LASIK)治疗首次术后残余近视的疗效及安全性 .方法 :对 75例 93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 (7.2±3.6 )mo.术后平均随访超过 6mo .采用配对t检验对数据进行统计学处理 .结果 :二次LASIK术后平均裸眼视力较术前显著提高 (P <0 .0 1 ) ,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 .0 5 ) ;术后 6mo时屈光度在±0 .5D以内者为 96 .8% (90眼 ) ,有 2 1 .5 % (2 0眼 )的术后裸眼视力大于术前矫正视力 .无危及视力的并发症出现 .结论 :使用飞点扫描技术的准分子激光设备行二次LASIK治疗残余近视安全。AIM: To evaluate the effectiveness and safety of laser in situ keratomileusis for residual myopia and astigmatism using a scanning spot laser. METHODS: Ninety three myopia eyes (from 75 patients) underwent secondary LASIK at (7.18±3.56) months after primary LASIK procedure and following up was over 6 months. The statistical analysis of the data was made by the paired test. RESULTS: After the reteatment, the average uncorrected visual acuity (UCVA) improved significantly ( P <0.01) but compared with the best corrected visual acuity (BCVA) after primary LASIK, the UCVA after secondary LASIK had no significant difference ( P >0.05). At 6 months, the residual refractive error within ±0.5D were 96.8% (90 eyes). Compared with the preoperative BCVA, 21.5% (20 eyes) had better postoperative UCVA and no severe complications were observed. CONCLUSION: Secondary LASIK, using a scanning spot excimer laser system, is an effective and safe method to treat regression after primary LASIK.
