摘要 目的:应用双通道客观视觉质量分析系统(OQAS)测量区域折射型(SBL-3)和衍射折射型(SN6AD1)多焦点人工晶状体(MIOL)植入术后患者的视觉质量。方法:选取2017-03/2018-04在我院行白内障超声乳化吸除联合人工晶状体植入术的年龄相关性白内障患者47例47眼。根据植入MIOL的不同分为SBL-3组(22例22眼)和SN6AD1组(25例25眼)。术后随访3mo,比较两组患者的裸眼及矫正远、中、近视力,并采用OQAS检查客观视觉质量。结果:术后3mo,SBL-3组患者裸眼中视力优于SN6AD1组[0.14(0.04,0.26)vs 0.26(0.12,0.40),P<0.05],客观散射指数[2.52(2.35,3.86)vs 1.89(1.39,2.28)]和人工晶状体眼伪调节力(2.47±0.88D vs 1.25±0.70D)均显著高于SN6AD1组,MTF-cut/off、SR及模拟对比度视力均显著低于SN6AD1组(P<0.01)。结论:SBL-3和SN6AD1 MIOL植入术后患者均能够获得较好的主观视觉质量,但OQAS系统能够反映二者产生的客观视觉质量差异。 AIM: To measure the optical quality after implantation of SBL-3 and SN6 AD1 multifocal intraocular lens(MIOL) in patients by a double-pass optical quality analysis system(OQAS).METHODS: Totally 47 cases of age-related cataract who received phacoemulsification and the implantation of MIOL were enrolled from March 2017 to April 2018 in Chengdu Aier Eye Hospital. According to the difference of implanted MIOLs, patients were divided into SBL-3 group(22 patients, 22 eyes) and SN6 AD1 group(25 patients, 25 eyes). Three months postoperatively, uncorrected distant visual acuity(UDVA), uncorrected intermediate visual acuity(UIVA), uncorrected near visual acuity(UNVA), corrected distant visual acuity(CDVA), corrected intermediate visual acuity(CIVA), corrected near visual acuity(CNVA), and objective optical quality measured by OQAS were all compared between two groups.RESULTS: Three months postoperatively, significant difference was found in UIVA [0.14(0.04, 0.26) vs 0.26(0.12, 0.40), P<0.05] which was better in SBL-3 group. Moreover, significantly higher values of OSI [2.52(2.35, 3.86) vs 1.89(1.39, 2.28)] and pseudophakic accommodation(2.47±0.88 D vs 1.25±0.70 D) were found in SBL-3 group. Significantly lower values of MTF-cut/off, SR, OV 100%, OV 20% and OV 9% were found in SBL-3 group(P<0.01).CONCLUSION: Both SBL-3 and SN6 AD1 MIOL could provide patients with good subjective visual quality, but OQAS could find the differences in visual quality after implantation of different MIOLs objectively.
