This study aimed to evaluate the usefulness of a new wet laboratory (wet lab) system using porcine eyes with eyelids.
Teaching device trial.
Porcine eyes with orbital tissues and eyelids.
Twenty porcine eyes with orbital tissues and eyelids were enucleated from pigs butchered at age 6 months. These eyes were positioned in the eye sockets of a model head and stabilized with a pin. Eye draping, dressing with tape, and speculum placement were conducted. The vertical and horizontal widths of the palpebra under the speculum setting were compared with those of 55 patients who underwent cataract surgery. The rotation and torsion of the porcine eye in the new wet lab system were also compared with those of a conventional wet lab system. For comparison with actual cataract surgery, 5 ophthalmologists, including residents, were asked to respond to a questionnaire survey.
The horizontal widths of the palpebra under the speculum setting were 27.5 ± 3.1 mm in porcine eyes and 28.6 ± 5.1 mm in human eyes, and the vertical widths were 16.9 ± 1.3 mm and 16.1 ± 1.5 mm (p = 0.53, 0.05). The amounts of rotation and torsion were significantly greater with the new wet lab system. Ophthalmologists evaluated the new wet lab system as being more realistic than the conventional system, in terms of both natural eye movement and restriction of the surgical field by the eyelid and the speculum.
Wet lab training using porcine eyes with eyelids is more practical than older systems as it reproduces an ocular surgical field very similar to that of humans.
本研究旨在评估一种使用带有眼睑的猪眼的新型湿实验室系统的实用性。
教学设备试验。
带有眼眶组织和眼睑的猪眼。
从6个月大的屠宰猪身上摘除20只带有眼眶组织和眼睑的猪眼。将这些眼睛放置在模型头部的眼窝中，并用销钉固定。进行眼部覆盖、用胶带包扎以及放置窥器。将窥器设置下眼睑的垂直和水平宽度与55例接受白内障手术的患者的相应宽度进行比较。还将新型湿实验室系统中猪眼的旋转和扭转与传统湿实验室系统中的情况进行了比较。为了与实际白内障手术进行比较，邀请了包括住院医师在内的5名眼科医生进行问卷调查。
窥器设置下猪眼睑的水平宽度为27.5±3.1毫米，人眼睑的水平宽度为28.6±5.1毫米；垂直宽度分别为16.9±1.3毫米和16.1±1.5毫米（p = 0.53，0.05）。新型湿实验室系统的旋转和扭转量明显更大。眼科医生认为，就自然眼球运动以及眼睑和窥器对手术视野的限制而言，新型湿实验室系统比传统系统更逼真。
使用带有眼睑的猪眼进行湿实验室训练比旧系统更实用，因为它能再现与人类非常相似的眼部手术视野。
