摘　　要：目的评价VERION数字导航系统行散光矫正型人工晶状体(Toric intraocular lens,Toric IOL)轴位标记的准确性和有效性。方法回顾性分析2016年6月至2017年5月行白内障超声乳化摘出联合Toric IOL植入术的患者75例(75眼),所有患者术前应用VERION数字导航系统采集眼前节图像并设定IOL预设植入轴位(目标轴位),并于裂隙灯下采用1 m L注射器针头标记水平轴位。术中随机参考VERION导航下的IOL目标轴位或裂隙灯下标记的目标轴位植入IOL,记为VERION组(42眼)和裂隙灯组(33眼),术后1 d、1周、1个月、3个月记录患者最佳矫正视力,散瞳后进行眼前节照相,应用Photoshop软件进行图像分析,比较两组患者术后不同时间点的最佳矫正视力以及IOL实际轴位与目标轴位的偏差值。结果 VERION组术后1 d、1周、1个月、3个月最佳矫正视力≥0.8氉的眼数所占比例分别为61.9%、78.6%、71.4%、76.2%,裂隙灯组分别为69.7%、78.8%、81.8%、75.8%,各时间点两组相比差异均无统计学意义(均为P>0.05)。VERION系统标记的IOL目标轴位与裂隙灯下针头标记的IOL目标轴位的差值为(3.04±1.99)°。两组患者术后不同时间点IOL实际轴位与目标轴位的偏差值均无统计学意义(均为P>0.05)。结论应用VERION数字导航系统行Toric IOL轴位标记,术后效果准确稳定。Objective To evaluate the accuracy and validity of Toric intraocular lens(IOL)alignment by VERION image guided system.Methods In this retrospective study,75 eyes of 75 patients who underwent phacomulsification combined with Toric IOL implantation were enrolled from June 2016 to May 2017.Before operation,anterior segment images of all patients were collected using VERION image guided system,and target axis of IOL implantation was set.Horizontal axis was marked using 1 mL syringe needle under the slit lamp.During the procedures,the IOL was implanted referring to the target axis under VERION system or the slit lamp randomly,and there were 42 eyes with IOL implantation guided by VERION system(VERION group),and 33 eyes guided by slit lamp(slit lamp group).The best corrected visual acuity(BCVA)of each patient was recorded at day 1,1 week,1 month,and 3 months after operation.Anterior segment images were taken after mydriasis,and all the images were analyzed by Photoshop software.Finally,the BCVA at various time points after operation and the deviation value of actual axis and target axis was compared in both groups.Results The proportion of eyes with BCVA≥0.8 at day 1,1 week,1 month,and 3 months after operation was 61.9%,78.6%,71.4%and 76.2%in VERION group,respectively,and 69.7%,78.8%,81.8%and 75.8%in slit lamp group,respectively,and there was no statistical significance between VERION group and slit lamp group(all P>0.05).The difference value of target axis marked by VERION system and by slit lamp was(3.04±1.99)°.No significant differences were seen in the IOL actual axis and target axis between the two groups at various time points(all P>0.05).Conclusion It is accurate and stable of VERION image guided system for toric IOL axis marking.
