摘　　要：目的:探究角膜/屈光分析仪OPD-Scan Ⅲ评估后发性白内障患者行Nd∶YAG激光术后视觉质量。方法:回顾性研究。选取2021-05/2023-04于我院行Nd∶YAG激光后囊膜切开术治疗的后发性白内障患者98例98眼,采用角膜/屈光分析仪OPD-Scan Ⅲ获取患者高阶像差参数(彗差、球差和三叶草像差)和视觉质量参数[斯特列尔比(SR)和人眼调制传递函数(MTF)曲线中4 mm面积比(AR)],比较患者术前,术后1 wk,3 mo时视力、高阶像差和视觉质量。结果:纳入患者手术前后裸眼远视力(UDVA)、裸眼中视力(UIVA)、裸眼近视力(UNVA)、彗差、球差、三叶草、SR和AR比较均有差异(均P<0.001)。术后1 wk,3 mo UDVA、UIVA、UNVA、彗差、球差、三叶草、SR和AR与术前比较均有差异(均P<0.05)。术后3 mo UDVA、UIVA、UNVA、SR和AR与术后1 wk比较均有差异(均P<0.05),术后3 mo彗差、球差、三叶草与术后1 wk比较均无差异(均P>0.05),术后3 mo球差、三叶草与SR均呈负相关(r_(s)=-0.427,P=0.009;r_(s)=-0.436,P=0.010),三叶草与AR呈负相关(r_(s)=-0.406,P=0.015)。结论:后发性白内障患者Nd∶YAG激光术后视力改善,使用角膜/屈光分析仪OPD-Scan Ⅲ系统反映患者视觉质量具有较高的临床价值。AIM:To explore the value of the corneal/refractive analyzer OPD-Scan Ⅲ in assessing visual quality after Nd∶YAG laser_(s)urgery in patients with posterior capsular opacification.METHODS:A total of 98 patients(98 eyes)with posterior capsular opacification who underwent Nd∶YAG laser posterior capsulotomy in our hospital from May 2021 to April 2023 were retrospectively selected as the research subjects,and higher-order aberration parameters(coma,spherical aberration and trefoil aberration)and visual quality parameters[Strehl ratio(SR)and 4 mm area ratio(AR)in the human eye modulation transfer function(MTF)curve]were obtained using the corneal/refractive analyzer OPD-Scan Ⅲ.The patient’s visual acuity,higher-order aberration parameters and visual quality before surgery,and at 1 wk and 3 mo after_(s)urgery were compared.RESULTS:There were statistically significant differences in uncorrected distance visual acuity(UDVA),uncorrected intermediate visual acuity(UIVA)and uncorrected near visual acuity(UNVA),coma,spherical aberration,trefoil aberration,SR and AR before and after_(s)urgery(all P<0.001),and there were statistically significant differences in UDVA,UIVA,UNVA,coma,spherical aberration,trefoil aberration,SR and AR at 1 wk and 3 mo postoperatively(all P<0.05).Additionally,there were differences in the UDVA,UIVA,UNVA,SR and AR at 3 mo postoperatively compared with those parameters at 1 wk postoperatively(all P<0.05),while there were no statistical significance in coma,spherical aberration,trefoil aberration at 3 mo postoperatively and those at 1 wk postoperatively(all P>0.05).Furthermore,the spherical aberration,trefoil aberration were negatively correlated with SR(r_(s)=-0.427,P=0.009;r_(s)=-0.436,P=0.010),and the trefoil aberration was negatively correlated with AR(r_(s)=-0.406,P=0.015).CONCLUSION:The visual acuity of patients with posterior capsular opacification improved after Nd∶YAG laser_(s)urgery,and the corneal/refractive analyzer OPD-Scan Ⅲ system has a high clinical value in reflecting patie
