摘要
目的探讨用ZeimerFemtoLDV飞秒激光制作角膜瓣准分子激光原位角膜磨镶术（LASIK）的安全性和效果。方法同期行LASIK治疗的近视198例（396眼）。根据角膜瓣制作方法分为两组：I组120例（240眼）用ZeimerFemtoLDV飞秒激光制作角膜瓣，Ⅱ组78例（156眼）用Mo—riaM：90Ixm机械刀制作角膜瓣，比较两组术后1d、1个月、6个月裸眼视力、最佳矫正视力、屈光度及高阶像差。结果两组角膜瓣制作都顺利；术后不同时间，两组的裸眼视力、最佳矫正视力的差异无统计学意义；术后1个月、6个月两组的屈光度比较，球镜的差异无统计学意义，但I组的残余散光低于Ⅱ组，差异有统计学意义；术后6个月，两组的总高阶像差、慧差、球差都较术前增加，但I组的总高阶像差和慧差的增加少于Ⅱ组，差异有统计学意义。结论FemtoLDV飞秒激光制瓣的LASIK与机械刀制瓣LASIK相比，术后视力无差别，但术后残余散光低，总高阶像差、慧差增加较少，视觉质量可能优于后者。
Objective To investigate the efficacy and safety of laser in situ keratomileusis （LASIK） with flap made by Zeimer Femto LDV. Methods There were 198 cases （396 eyes） envolved. The patients were divided into 2 groups： 120 patients （240 eyes） whose LASIK flaps were made with Zeimer Femto LDV femtosecond laser in group I,and 78 patients（ 156 eyes） whose flaps were created with Moria M2 90 μm microkeratome in group II. Uncorrected visual acuity, corrected visual acuity, refractive diopter, high order aberrations were checked and recorded preoperatively, and 1 day, 1 month and 6 months postoperative- ly. Results All flaps were made very well in the 2 groups. The uncorrected visual acuity and corrected visual acuity had no significant difference between the 2 groups at all time points measured. At the 1 st month and sixth month postoperative timepoint, the residual astigmatism was significantly lower in group I than that in group II,but there was no significant sphere differene between the 2 groups. Sixth month postoperatively, the high order aberrations,spherical aberration and coma aberration increased in the 2 groups, but the high order aberration and coma aberration were significantly lower in group I than that in group II. Conclusion It is safe and efficacious to correct myopia and astigmatism with LASIK flap made by Zeimer Femto LDV, with less high order aberration and less coma aberration. It might improve postoperative visual quality.
