To compare the surgical workload, complications, and visual outcomes using the three-dimensional visualization system with the conventional microscope in phacoemulsification cataract surgery.
Prospective, non-randomized, open-label interventional study.
All patients underwent phacoemulsification cataract surgery using the three-dimensional visualization system or conventional microscope.
Of the 203 eyes, 80 underwent surgery with the three-dimensional system while 123 underwent with the conventional microscope. No difference was noted in the total surgical duration, complication rates, and visual outcomes between the two groups. However, capsulorhexis was significantly faster using the conventional microscope while posterior chamber intraocular lens insertion was quicker using the three-dimensional system. In terms of cognitive workload comparison, no difference was seen in the surgeons' heart rate, oxygen saturation levels, and surgery task load index total workload score and workload score for all six dimensions of the questionnaire, between the three-dimensional system and conventional microscope groups. As compared to baseline, the heart rate increased significantly during all surgical steps and at the end in both groups. When compared to baseline, the oxygen saturation levels were significantly raised during capsulorhexis, irrigation, and aspiration and posterior chamber intraocular lens insertion and at the end of the surgery in the three-dimensional group and during incision and at the end of the surgery in the conventional microscope group.
The duration of surgery, complications, and visual acuity outcomes remain unaffected while performing phacoemulsification cataract surgeries with the three-dimensional viewing system when compared to the conventional microscopes. Moreover, the surgeons' cognitive workload too remains unaffected while utilizing this revolutionary three-dimensional surgical technology.
比较三维可视化系统与传统显微镜在白内障超声乳化手术中的手术工作量、并发症和视觉效果。
前瞻性、非随机、开放标签的干预性研究。
所有患者均采用三维可视化系统或传统显微镜行白内障超声乳化手术。
203 只眼中，80 只眼行三维系统手术，123 只眼行传统显微镜手术。两组患者的总手术时间、并发症发生率和视觉效果无差异。然而，在囊膜切开和后房型人工晶状体插入方面，传统显微镜明显更快，而在三维系统中则更快。在认知工作量比较方面，三维系统组和传统显微镜组的心率、血氧饱和度水平以及手术任务负荷指数总工作量评分和问卷的六个维度的工作量评分无差异。与基线相比，两组患者的心率在所有手术步骤和手术结束时均显著增加。与基线相比，三维组在囊膜切开、冲洗、抽吸和后房型人工晶状体插入以及手术结束时，以及传统显微镜组在切口和手术结束时，血氧饱和度水平显著升高。
与传统显微镜相比，使用三维观察系统进行白内障超声乳化手术时，手术时间、并发症和视力结果保持不变。此外，在使用这项革命性的三维手术技术时，外科医生的认知工作量也不受影响。
