目的。目的比较两种不同类型人工晶状体在带凸缘人工晶状体固定术中的近期临床效果。方法：研究方法。这项研究是一项回顾性病例系列研究，包括2017年6月至2018年7月在广岛大学医院接受法兰人工晶状体固定术的患者。使用两种不同的三片人工晶状体(NX-70和PN6A)。将植入NX-70人工晶状体和植入PN6A人工晶状体的患者分为1组(15只眼)和2组(25只眼)。分析患者特点、手术结果及术后并发症。我们排除了有术后随访结果的患者。平均随访时间为13.3+/-11.7周。术后最佳矫正视力1组为0.10±-0.33，2组为0.26±-0.42。平均手术时间分别为11.2±-4.54min和7.00±2.20min(P=0.0024)。未行周边虹膜切开术的13只眼中有3只眼(23%)发生虹膜夹持。组1未行周边虹膜切开术，未行周边虹膜切开术，但未发生虹膜夹持。结论。使用NX-70人工晶状体有减少术中、术后并发症的趋势。PN6A人工晶状体在前房内操作方便，手术时间短。选择合适的人工晶状体用于带凸缘的人工晶状体固定术需要了解其术中和术后并发症的特点。
Purpose. To compare short-term clinical outcomes between two different intraocular lens (IOL) types in the flanged IOL fixation technique. Methods. This study was a retrospective case series and included the patients who underwent flanged IOL fixation between June 2017 and July 2018 at the Hiroshima University Hospital. Two different 3-piece IOLs (NX-70 and PN6A) were used. Recipients of NX-70 and PN6A IOLs were classed into groups 1 (15 eyes) and 2 (25 eyes), respectively. Patient characteristics, surgical results, and postoperative complications were analyzed. We excluded patients with a postoperative follow-up of Results. The mean follow-up period was 13.3 +/- 11.7 weeks. The postoperative best corrected visual acuity, in logarithm of the minimum angle of resolution (logMAR), was 0.10 +/- 0.33 in group 1 and 0.26 +/- 0.42 in group 2. The mean operation times for groups 1 and 2 were 11.2 +/- 4.54 minutes and 7.00 +/- 2.20 minutes, respectively (p=0.0024). Detachment of the IOL haptic from the optic during surgery occurred in four eyes in group 2 (16%), but did not occur in group 1. Iris capture of the optic was observed in 3 of the 13 eyes (23%) without a peripheral iridotomy in group 2. No peripheral iridotomies were performed on group-1 eyes, but iris capture did not occur in that group. Conclusions. There was a trend to fewer intraoperative and postoperative complications when using NX-70 IOLs. On the other hand, PN6A IOLs was easy to maneuver within the anterior chamber, and the operation time was shorter when using PN6A IOLs. Selection of optimal IOLs for flanged IOL fixation necessitates an understanding of their characteristics in terms of intraoperative and postoperative complications.
