To design and validate a feasible simulation to address an identified training gap in the management of intraoperative vitreous loss.
Our simulation consists of a two-part non-toxic mixture that polymerises upon contact within a silicone training eye, to resemble the appearance of vitreous after staining with triamcinolone. This gel can be cut and aspirated with an anterior vitrectomy probe. Experienced consultant ophthalmic surgeons were invited to assess the simulation and anonymously complete validity questionnaires.
Seven senior surgeons participated. Four (57%) strongly agreed and three (43%) agreed that the tissue behaved like vitreous. Six (86%) strongly agreed and one (14%) agreed that instrument handling was realistic. Three (43%) strongly agreed and four (57%) agreed that simulated triamcinolone staining was realistic. Four (57%) strongly agreed and three (43%) agreed that the simulation was visually convincing. Six (86%) strongly agreed and one (14%) agreed that this simulation is useful for training. No participants disagreed with any validity statements.
This novel simulation of anterior vitrectomy has good face and content validity, with unanimous agreement among experienced surgeons of its utility for training in the management of intraoperative vitreous loss.
设计并验证一种可行的模拟方案，以解决术中玻璃体丢失管理方面的一个已确定的培训差距。
我们的模拟方案由两部分组成，它们在硅酮训练眼球内接触时会聚合，类似于用曲安奈德染色后的玻璃体外观。这种凝胶可以用前玻璃体切除术探头切割和抽吸。我们邀请了经验丰富的顾问眼科外科医生来评估模拟方案，并匿名填写有效性调查问卷。
有 7 名资深外科医生参与了研究。其中 4 人（57%）强烈同意，3 人（43%）同意该组织的行为类似于玻璃体。6 人（86%）强烈同意，1 人（14%）同意仪器操作具有现实性。3 人（43%）强烈同意，4 人（57%）同意模拟曲安奈德染色具有现实性。4 人（57%）强烈同意，3 人（43%）同意该模拟方案在视觉上具有说服力。6 人（86%）强烈同意，1 人（14%）同意该模拟方案对于培训术中玻璃体丢失的管理非常有用。
这种新型的前玻璃体切除术模拟具有良好的表面和内容有效性，经验丰富的外科医生一致认为其在培训术中玻璃体丢失管理方面非常有用。
