摘要:
目的　观察飞秒激光辅助准分子激光原位角膜磨镶术（FS-LASIK）术中调整不同屈光度治疗高度近视的疗效，找到切削屈光度的最佳调整方案。方法　选择2018年3月至2018年5月于新乡医学院第一附属医院眼科行FS-LASIK治疗92例高度近视患者为研究对象，将其右眼纳入研究。根据术中切削屈光度不同将-6.00 D≤等效球镜度<-7.00 D 32眼分为全矫组和-0.25 D组、-7.00 D≤等效球镜度<-8.00 D 34眼分为-0.25 D组和-0.50 D组、-8.00 D≤等效球镜度<-9.00 D 26眼分为-0.50 D组和-0.75 D组。3组患者术中给予不同的切削屈光度。观察各组患者术后1、3、6个月的裸眼视力及屈光度。结果　术后1、3、6个月，全矫组和-0.25 D组患者裸眼视力和屈光度均显著优于术前（P<0.05），-0.25 D组患者裸眼视力及屈光度均优于全矫组（P<0.05）；-0.25 D组和-0.50 D组患者裸眼视力和屈光度均显著优于术前 （P<0.05），-0.50 D组患者裸眼视力及屈光度均优于-0.25 D组（P<0.05）；-0.50 D组和-0.75 D组患者裸眼视力和屈光度均显著优于术前（P<0.05），-0.75 D组患者裸眼视力及屈光度均优于-0.50 D组（P<0.05）。 结论　SCHWIND AMARIS 500E准分子激光仪治疗高度近视时，-6.00 D≤等效球镜度数<-7.00 D患者的切削屈光度减去-0.25 D、-7.00 D≤等效球镜度<-8.00 D患者的切削屈光度减去-0.50 D、-8.00 D≤等效球镜度<-9.00 D患者的切削屈光度减去-0.75 D，术后可获得满意的裸眼视力及屈光度。
Abstract:
Objective　To observe the effects of femtosecond laser-assisted excimer laser in situ keratomileusis(FS-LASIK) in the treatment of high myopia adjusted cutting diopter and to find the best adjustment scheme of the cutting refraction.Methods　From March 2018 to May 2018，92 patients with high myopia treated with FS-LASIK in the Department of Ophthalmology，the First affiliated Hospital of Xinxiang Medical University were selected as the subjects，and their right eyes were included in the study.According to the intraoperative cutling diopter,32 eyes with -6.00 D ≤ equivalent spherical lens <-7.00 D were divided into total correction group and -0.25 D group,34 eyes with - 7.00 D ≤ equivalent spherical lens <-8.00 D were divided into -0.25 D group and -0.50 D group,26 eyes with - 8.00 D ≤ equivalent spherical lens <-9.00 D were divided into -0.50 D group and -0.75 D group.The patients in the three groups were given different intraoperative cutting diopter.The uncorrected visual acuity and diopter of the patients in each group were observed at 1，3 and 6 months after operation.Results　At 1,3,6 months after operation,the uncorrected visual acuity and diopter of the patients in the total correction group and -0.25 D group were significantly better than those preoperation (P<0.05)，and the uncorrected visual acuity and diopter of the patients in the -0.25 D group were significantly better than those in the total correction at 1，3 and 6 months after operation (P<0.05).The uncorrected visual acuity and diopter of the patients in the -0.25 D group and -0.50 D group at 1，3 and 6 months after operation were significantly better than those preoperation (P<0.05).And the uncorrected visual acuity and diopter of the patients in the -0.50 D group were better than those in the -0.25 D group at 1，3 and 6 months after operation (P<0.05).The uncorrected visual acuity and diopter of the patients in the -0.50 D group and -0.75 D group at 1,3 and 6 months postoperation were significantly better than those preoperation (P<0.05)，and the uncorrected visual acuity and diopter of patients in the -0.75 D group were better than those in the -0.50 group at 1,3 and 6 months postoperation (P<0.05).Conclusion　Satisfactory results are obtained in patients with high myopia treated with SCHWINDAMARIS 500E excimer laser instrument with -6.00 D≤equivalent spherical lens<-7.00 D minus -0.25 D，patients with -7.00 D≤equivalent spherical lens <-8.00 D minus -0.50 D，patients with -8.00 D≤equivalent spherical lens<-9.00 D minus 0.75 D.
