有晶状体眼后房型人工晶状体植入与FS-LASIK术后视觉质量分析

Analysis of visual quality after posterior chamber ICL implantation and FS-LASIK

目的:比较有晶状体眼后房型人工晶状体(ICL)植入与FS-LASIK术治疗中高度近视术后的视觉质量。方法:前瞻性研究。选取2018-06/12分别行ICL植入术和FS-LASIK术的近视患者58例116眼(ICL组)和48例96眼(FS-LASIK组)。分析比较两组患者手术前后屈光度、视力和视觉质量情况。结果:术后3mo,ICL组患者球镜度数高于FS-LASIK组(0.19±0.22D vs 0.09±0.29D,P<0.05),但两组患者视力、柱镜度数和等效球镜度数无差异(均P>0.05);ICL组患者调制传递函数截止频率(MTF cut off)、客观散射指数(OSI)和OV9%均明显优于FS-LASIK组,而SR较FS-LASIK组降低,且与术前相比,ICL组患者MTF cut off明显增高,SR、OSI值降低,FS-LASIK组患者SR值降低(均P<0.05)。结论:ICL植入和FS-LASIK术均可有效改善患者视力和屈光度,对于中高度近视患者ICL植入术可提供相对较好的视觉质量。

AIM: To compare the visual quality between implantable collamer lens (ICL) implantation and FS-LASIK for correcting moderate and high myopia. METHODS: Prospective study. Choose in June 2018 to December 2018 for ICL implantation of 58 patients (116 eyes) and 48 patients (96 eyes) underwent FS-LASIK. The diopter, visual acuity and visual quality of the two groups before and after surgery were analyzed and compared. RESULTS: After 3mo operation, the degree of spherical mirror in the ICL group was higher than that in the FS-LASIK group (0.19±0.22D vs 0.09±0.29D, P <0.05), but there was no difference in visual acuity, lenticule degree and spherical equivalent between the two groups ( P >0.05). The modulation transfer function cut off frequency (MTF cut off), objective scatter index (OSI) and OV9% were significantly better in the ICL group than in the FS-LASIK group, while the SR was lower than the FS-LASIK group. Compared with the former, the MTF cut off was significantly increased in the ICL group, the SR and OSI values were decreased, and the SR value was decreased in the FS-LASIK group (all P <0.05). CONCLUSION: Both ICL implantation and FS-LASIK can effectively improve the visual acuity and diopter of patients, ICL implantation for patients with moderate and high myopia provides relatively good visual quality.
