摘要
目的探讨准分子激光小光斑飞点扫描联合主动眼球跟踪系统矫正近视的治疗效果及优越性。方法采用鹰视Allegretto准分子激光治疗仪及MORIA-2角膜切削刀(130μm刀头)对415例(815眼)近视眼患者行LASIK治疗。按术前屈光度将患者分为4组I组-1.25～-3.00D(105眼),II组-3.25～-6.00D(446眼),III组-6.25～-10.00D(233眼),IV组-10.25～-14.00D(31眼)。术后追踪观察6～12mo。结果所有患者术后的裸眼视力(UCVA)均达到0.6以上,其中97.7%达到1.0,84.2%达到1.2,38.8%达到1.5,6.7%达到2.0。110眼(13.5%)的术后裸眼视力和150眼(18.4%)的术后最佳矫正视力分别大于术前最佳矫正视力。术后屈光度在预期矫正度±1.0D以内者为91.6%,在预期矫正度±0.5D以内者为85.2%。结论准分子激光小光斑飞点扫描联合主动眼球跟踪系统矫正近视的临床效果良好,是一种安全、有效的技术,值得在临床积极推广应用。
AIM: To explore the clinical efficacy of correcting myopia using a scanning-spot excimer laser combined with active eye tracking system.· METHODS: A total of 415 cases (815 eyes) with myopia were treated by LASIK using allegretto excimer system (wavelight laser technologie AG) and Moria-2 cornea ablation knife (130μm). All of the cases were divided into 4 groups according to their diopters: Group I: -1.25- -3.00D (105 eyes), Group II: -3.25- -6.00D (446 eyes), Group III: -6.00- -10.00D (233 eyes) and Group IV: -10.25-14.00D (31 eyes). The follow-up was 6-12mo.· RESULTS: The postoperative uncorrected visual acuity (UCVA) for all cases was 0.6 or better, and 6.7%, 38.8%, 84.2% and 97.7% of cases had UCVA 2.0, 1.5, 1.2 and 1.0 respectively. The rate of the postoperative UCVA and best-corrected visual acuity (BCVA) better than the preoperative BCVA were 13.5% (110 eyes) and 18.4% (150 eyes) respectively. The residual refractive error within ±0.50D, ±1.00D were 85.2% and 91.6% respectively.· CONCLUSION: The clinical efficacy of correcting myopia using a scanning-spot excimer laser combined with active eye tracking system was good. It is a safe, effective and valuable technique for clinical application. ·
