摘　　要：目的: 探究2种不同类型单焦点人工晶状体(IOL)经睫状体平坦部巩膜缝线固定术后视觉质量的差异。方法: 回顾性系列病例研究。选取2019年6月至2020年6月就诊于潍坊眼科医院因外伤导致无法囊袋内植入IOL的患者42例(42眼), 所有患者均接受二期经睫状体平坦部IOL巩膜缝线固定术, 其中植入Zeiss CT Lucia 601PY单焦点后房型IOL 25例(25眼)作为601PY组;植入AQBH单焦点后房型IOL 17例(17眼)作为AQ组。术后随访6~12个月, 观察2组患者手术前后的最佳矫正视力(BCVA)、调制传递函数截止频率(MTF cutoff)、客观散射指数(OSI)、等效球镜度(SE)等差异。数据采用Mann-WhitneyU秩和检验、独立样本t检验进行分析。结果: 601PY组、AQ组患者手术前、后BCVA差异均无统计学意义(Z=-1.39, P=0.164;Z=-0.36, P=0.721)。2组术后BCVA差异无统计学意义(Z=-1.24, P=0.215)。2组术后MTF cutoff、OSI值差异有统计学意义(t=2.15, P=0.043;t=-2.22, P=0.038)。2组术后SE差异无统计学意义(Z=-0.65, P=0.517)。结论: 单焦点IOL经睫状体平坦部巩膜缝线固定术可获得较好的视力和视觉质量, 但不同类型单焦点IOL术后视觉质量存在差异, 其中Zeiss CT Lucia 601PY IOL略优于AQBH IOL。Objective:To evaluate the difference in visual acuity and visual quality after pars plana sutured fixation of two different sonofocal intraocular lens(SIOL).Methods:This was a retrospective case-observational study.Forty-two patients(42 eyes)unable to implant an intraocular lens(IOL)in the capsular due to trauma at Weifang Eye Hospital from June 2019 to June 2020 were enrolled in the study.All patients underwent IOL sutured scleral fixation via pars plana.Among them,25 patients(25 eyes)implanted with Zeiss CT Lucia 601PY IOL in group 601PY,17 patients(17 eyes)implanted with AQBH IOL in group AQ.Followup time was 6-12 months.Best corrected visual acuity(BCVA)before and after surgery,modulation transfer function cut off frequency(MTF cutoff),objective scatter index(OSI)and spherical equivalent(SE)after surgery were analyzed by the Mann-Whitney rank test,independent sample t-test.Results:In group 601PY,there was no significant difference in BCVA before and after surgery(Z=-1.39,P=0.164).In group AQ,there was no significant difference in BCVA before and after surgery(Z=-0.36,P=0.721).There was no difference in postoperative BCVA between the two groups(Z=-1.24,P=0.215).Significant differences existed between the two groups in MTF cutoff and OSI(t=2.15,P=0.043;t=-2.22,P=0.038).There was no significant difference in postoperative SE between the two groups(Z=-0.65,P=0.517).Conclusions:Sonofocal IOL sutured scleral fixation via pars plana can obtain good visual acuity and visual quality,but the postoperative visual quality differences exist due to different IOL,The Zeiss CT Lucia 601PY IOL was slightly superior to the AQBH IOL.
