方法：前瞻性非随机对照研究。选取2020-01/06在我院行白内障超声乳化联合IOL植入术治疗的年龄相关性白内障患者100例103眼，根据患者自主选择的手术方式进行分组：术中使用传统双目显微镜为对照组52例53眼； 术中使用Ngenuity 3D设备为3D组48例50眼，3D组根据病例纳入时间分为2020-01/03为3D-1组24例25眼，2020-04/06为3D-2组24例25眼。记录三组患者的总手术时间及各步骤(撕囊、超声乳化、吸除皮质、IOL植入、吸除黏弹剂)操作时间、超声乳化时间(UST)、累计能量复合参数(CDE)、液流损耗、并发症情况。比较三组患者术前和术后1mo裸眼视力(UCVA)、最佳矫正视力(BCVA)、眼压(IOP)和角膜内皮细胞计数(CECC)。

结果：3D-1组总手术时间、撕囊时间、超声乳化操作时间、吸除黏弹剂时间显著高于对照组(均P<0.01)。3D-2组总手术时间和手术各步骤时间与对照组相比均无差异(均P>0.05)。3D-1组术中UST、液流损耗、CDE显著高于对照组(均P<0.05)。3D-2组术中各参数与对照组相比无差异(均P>0.05)。三组间患者术后1mo UCVA、BCVA、IOP、CECC比较均无差异(均P>0.05)。

结论：3D可视化技术下行白内障超声乳化联合IOL植入术安全有效，经过一定的学习曲线后，其手术效率与传统双目镜相比无显著差异。

METHODS: Prospective non-randomized controlled clinical study. A total of 100 patients(103 eyes)who underwent phacoemulsification combined with IOL implantation were enrolled in the study. Among them, according to the way of surgery chosen by the participants, 24 cases(25 eyes)were enrolled from January to March 2020(3D-1 group), 24 cases(25 eyes)were enrolled from April to June 2020(3D-2 group), and 52 cases(53 eyes)were enrolled from January to June 2020(binocular microscope group)as the control group. Total operative time, capsulorhexis time, phacoemulsification operation time, cortical aspiration time, IOL implantation time, viscoelastic agent aspiration time, ultrasound time(UST), cumulative dissipated energy(CDE), fluid flow loss, intraoperative and postoperative complications were recorded in the three groups. Uncorrected visual acuity(UCVA), best corrected visual acuity(BCVA), intraocular pressure(IOP)and corneal endothelial cell count(CECC)were recorded preoperatively and 1mo postoperatively.

RESULTS: The total operative time, the time of capsulorhysis, the operation time of phacoemulsification, and the time of removing viscoelastic agent between 3D-1 group and control group were statistically significant(all P<0.01). There were no significant differences in the total operation time and each operation step time between the 3D-2 group and the control group(all P>0.05). The differences of UST, liquid flow loss, and CDE between 3D-1 group and the control group were statistically significant(all P<0.05). There were no significant differences between the 3D-2 group and the control group in intraoperative parameters(all P>0.05). There were no statistical significances in UCVA, BCVA, IOP, and CECC among the three groups 1mo after surgery(all P>0.05).

CONCLUSION: Phacoemulsification combined with IOL implantation using 3D visualization technology is safe and feasible. After a certain learning curve period, there is no significant difference in the surgical efficiency compared with traditional binocular surgery.
