摘　　要：目的：探讨Visu Max飞秒激光制瓣准分子激光原位角膜磨镶术（laser in situ keratomileusis,LASIK）对近视的疗效。方法：应用Visu Max飞秒激光制瓣LASIK术治疗160眼近视患者,比较治疗后1 d、1周、1月、3月、6月及1年时的裸眼视力,角膜厚度≤500μm 20眼术中设计厚度与术后实际厚度,治疗前及治疗后1月、6月时的泪膜破裂时间（BUT）,观察术中及术后并发症。结果：治疗后,患者裸眼视力≥1.0的比例随着时间的推移而逐渐升高,达到手术预期效果;角膜厚度≤500μm 20眼术中设计的角膜瓣厚度与术后实测厚度比较,差异无统计学意义（t=-1.991,P=0.061）;治疗1月及6月时的BUT显著高于治疗前（t=-5.183、-3.062,P〈0.05）;治疗1月与6月比较,差异无统计学意义（P〉0.05）;术中有1眼发生结膜下出血,1~2周逐渐吸收。结论：Visu Max飞秒激光制瓣LASIK术治疗近视效果良好,对薄角膜瓣的预测性强。Objective： To evaluate the clinical effect of laser in situ keratomileusis （LASIK） by Vi- suMax femtosecond laser for myopia. Methods： A total of myopic patients （ 160 eyes） were treated with VisuMax LASIK femtosecond laser. The uncorrected visual acuity （UCVA） was compared be- tween patients of I day, 1 week, 1 month, 3 months, 6 months and 1 year after treatment. The postop- erative corneal flap thickness and preoperative design corneal flap thickness was compared in 20 eyes operation of 500 μm or less of corneal flap thickness. The postoperative breakup time of tear film （BUT） 1 month and 6 month after operation was compared with that of preoperative data. Results： Af- ter treatment, the proportion of patients＂ visual acuity of more than 1.0 gradually increased with the passage of time, and reached the expected effect of surgery. There was no statistically significant differ- ence between the postoperative corneal flap thickness and preoperative design corneal flap thickness in 20 eyes operation of 500μm or less of corneal flap thickness （ t = - 1. 991, P = 0.061 ）. After treat- ment for 1 month and 6 months, BUT was significantly higher than before treatment （t = -5. 183, - 3.062, P 〈 0.05） and there was no statistically significant difference in BUT between 1 month treat- ment and 6 months treatment （P 〉 0.05 ）. During the operation, there was 1 eye of conjunctival hem- orrhage, which was gradually absorbed within 1 to 2 weeks. Conclusion： VisuMax LASIK has a good effect in the treatment of myopia, and the prediction of the thin corneal flap is very strong.
