Background: To determine whether there is a significant saving of time when using a digital cataract workflow for digital data transfer compared to a manual approach of biometry assessment, data export, intraocular lens calculation, and surgery time. Methods: In total, 48 eyes of 24 patients were divided into two groups: 24 eyes were evaluated using a manual approach, whereas another 24 eyes underwent a full digital lens surgery workflow. The primary variables for comparison between both groups were the overall time as well as several time steps starting at optical biometry acquisition until the end of the surgical lens implantation. Other outcomes, such as toric intraocular lens misalignment, reduction of cylinder, surgically induced astigmatism, prediction error, and distance visual acuity were measured. Results: Overall, the total diagnostic and surgical time was reduced from 1364.1 ± 202.6 s in the manual group to 1125.8 ± 183.2 s in the digital group (p < 0.001). The complete time of surgery declined from 756.5 ± 82.3 s to 667.3 ± 56.3 (p < 0.0005). Compared to the manual approach of biometric data export and intraocular lens calculation (76.7 ± 12.3 s) as well as the manual export of the reference image to a portable external storage device (26.8 ± 5.5 s), a highly significant saving of time was achieved (p < 0.0001). Conclusions: Using a software-based digital approach to toric intraocular lens implantation is convenient, more efficient, and thus more economical than a manual workflow in surgery practice.
为了确定与生物测量评估、数据导出、人工晶状体计算和手术时间的手动方法相比，使用数字白内障工作流程进行数字数据传输时是否能显著节省时间。方法：总共24例患者的48只眼被分为两组：24只眼采用手动方法进行评估，而另外24只眼采用完整的数字晶状体手术工作流程。两组之间进行比较的主要变量是总时间以及从光学生物测量采集开始到手术晶状体植入结束的几个时间步骤。还测量了其他结果，如散光人工晶状体的偏心、柱镜减少、手术引起的散光、预测误差和远距离视力。结果：总体而言，手动组的总诊断和手术时间从1364.1±202.6秒减少到数字组的1125.8±183.2秒（p<0.001）。手术总时间从756.5±82.3秒降至667.3±56.3秒（p<0.0005）。与生物测量数据导出和人工晶状体计算的手动方法（76.7±12.3秒）以及将参考图像手动导出到便携式外部存储设备（26.8±5.5秒）相比，实现了显著的时间节省（p<0.0001）。结论：在手术实践中，使用基于软件的数字方法进行散光人工晶状体植入比手动工作流程更方便、更高效，因此更经济。
