摘　　要：目的比较飞秒激光辅助角膜原位磨镶术(FS-LASIK)与角膜塑形镜(OK)治疗后中低度近视患者的客观视觉质量。方法招募2018年10月至2019年12月收治的中低度成人近视患者98例,根据患者要求选择OK或FS-LASIK矫正近视各49例,均采用右眼作为研究对象,即OK组49例49眼,FS-LASIK组49例49眼,在治疗前和治疗3个月,采集两组的裸眼视力(UCVA)及散射指数(OSI),调制传递函数(MTF)、斯特列尔比值(SR)和光学质量分析系统(OQAS)值(OVs)的客观视觉质量参数。结果两组治疗前和治疗3个月UCVA组间比较差异无统计学意义(均P>0.05)。与治疗前相比,两组治疗3个月UCVA组内差异均有统计学意义(均P<0.01)。两组治疗3个月的OSI分别较基线值增加,而MTF、SR、OV100、OV20及OV9分别较基线值下降,组内差异均有统计学意义(均P<0.01)。治疗3个月,FS-LASIK组的OSI较OK组降低,而MTF、SR、OV100、OV20及OV9均较OK组增加,组间差异均有统计学意义(均P<0.01)。结论FS-LASIK与OK镜改善中低近视患者的裸眼视力无差异,但FS-LASIK组客观视觉质量效果更优。Objective To compare the objective visual quality of patients with low to moderate myopia after femtosecond laser assisted laser in situ keratomileusis(FS-LASIK)and orthokeratology(OK)lens.Methods From October 2018 to December 2019,98 patients with low to moderate adult myopia were recruited.According to the requirements of patients,49 cases corrected by OK,and 49 cases by FS-LASIK.Right eyes were used as the research objects,that was,49 eyes in OK group,and 49 eyes in FS-LASIK group.Before treatment and 3 months after treatment,uncorrected visual acuity(UCVA)and ocular scattering index(OSI)as well as objective visual quality parameters including modulation transfer function(MTF),Strehl ratio(SR)and optical quality analysis system(OQAS)values(OVs)were collected.Results There was no statistically significant difference in UCVA before treatment and 3 months after treatment between the two groups(all P>0.05).3 months after treatment,difference of UCVA within group was all statistically significant while comparing with those before treatment(all P<0.01).After 3 months of treatment,the OSI of the two groups respectively increased while comparing with the baseline value,but MTF,SR,OV100,OV20,and OV9 respectively decreased while comparing with the baseline value,difference within group was all statistically significant(all P<0.01).The OSI of the FS-LASIK group was significantly lower than that of the OK group,while MTF,SR,OV100,OV20 and OV9 were significantly higher than those of the OK group at 3 month after treatment,difference within group was all statistically significant(all P<0.01).Conclusion There is no significant difference between FS-LASIK and OK in improving UCVA of patients with low to moderate myopia,but the FS-LASIK group have better effects on objective visual quality.
