This study aimed to compare the efficacy of robot-assisted and manual cannula insertion in simulated big-bubble deep anterior lamellar keratoplasty (DALK). Novice surgeons with no prior experience in performing DALK were trained to perform the procedure using manual or robot-assisted techniques. The results showed that both methods could generate an airtight tunnel in the porcine cornea, and result in successful generation of a deep stromal demarcation plane representing sufficient depth reached for big-bubble generation in most cases. However, the combination of intraoperative OCT and robotic assistance received a significant increase in the depth of achieved detachment in non-perforated cases, comprising a mean of 89% as opposed to 85% of the cornea in manual trials. This research suggests that robot-assisted DALK may offer certain advantages over manual techniques, particularly when used in conjunction with intraoperative OCT.
本研究旨在比较机器人辅助与手动套管插入在模拟大泡深板层角膜移植术（DALK）中的疗效。对之前没有进行DALK经验的新手外科医生进行培训，使其使用手动或机器人辅助技术来实施该手术。结果显示，两种方法均可在猪角膜中形成气密隧道，且在大多数情况下能成功形成深基质分界平面，表明达到了足以产生大泡的深度。然而，在未穿孔的病例中，术中光学相干断层扫描（OCT）与机器人辅助相结合使得分离深度显著增加，手动操作试验中平均分离深度为角膜的85%，而在联合使用术中OCT与机器人辅助的试验中，这一比例为89%。本研究表明，机器人辅助的DALK可能比手动技术具有某些优势，尤其是在与术中OCT联合使用时。
