METHODS: Feasibility was assessed in synthetic eye models in two stages: Stage I, nonimplantable robot-assisted goniotomy; and Stage II, robot-assisted stent implantation using a trabecular bypass stent. Robot-assisted interventions were subsequently compared to the manual approach.
RESULTS: Stage I: Two surgeons completed 10 trials each of ab-interno sectoral goniotomy with and without robotic assistance for at least 3 clock hours using a standard goniotomy knife and more than 10 clock hours of extended goniotomy using a flexible, guided goniotomy instrument. Stage II: Trabecular bypass stent deployment was successfully achieved in 100% of the attempts with and without robotic assistance. Surgical time was recorded and compared between the robotic-assisted and the manual approach.
CONCLUSIONS: A system for robot-assisted microinvasive glaucoma surgery can successfully achieve implantable and nonimplantable interventions in the anterior segment. This is the first known demonstration of the feasibility of robot-assisted glaucoma surgery.
方法:在合成眼模型中评估了两个阶段的可行性:第一阶段,非植入式机器人辅助性腺切开术;第二阶段,使用小梁旁路支架的机器人辅助支架植入。随后将机器人辅助干预与手动方法进行了比较。
结果:第一阶段:两名外科医生完成了10项试验,每次进行有或没有机器人辅助的ab-interno部门性腺切开术至少3个小时,使用标准性腺切开术刀和超过10个小时的延长性腺切开术使用灵活,引导性腺切开术器械。阶段II:在有和没有机器人辅助的情况下,在100%的尝试中成功实现了小梁旁路支架部署。记录手术时间,并在机器人辅助和手动方法之间进行比较。
结论:机器人辅助的微创青光眼手术系统可以成功地在眼前段实现植入式和非植入式干预。这是机器人辅助青光眼手术可行性的第一个已知证明。
